Baker SPD CENTRIFUGAL PUMP PARTS CENTRIFUGAL PUMP PARTS CENTRIFUGAL PUMP SHAFT Since the impeller end of the shaft is exposed to the fluid in the 1-7/8 in. pump, Baker SPD has chosen a Stainless Steel shaft to prevent corrosion. The shaft is designed to transmit the required horsepower for maximum output in the most severe applications. Other specialized shaft designs are available upon request. CENTRIFUGAL PUMP IMPELLER A semi-open design has been selected for all sizes from the 2 x 3R x 13 in. to the 6 x 8R x 13 in. The semi-open vane design provides efficient fluid intake and discharge through the power side of the Impeller. The Impeller is designed with back vanes, which reduces wear on the Stuffing Box face. The back vanes also reduce the wear by limiting the inflow of solids to the Stuffing Box, thus enhancing the life of the sealing mechanism. CENTRIFUGAL PUMP BEARINGS Baker SPD specifies bearings of the highest quality from premier bearing manufacturers. The bearings are interchangeable with other popular 1-7/8 in. pump models. Both the Inboard and the Outboard Bearings are single row angular contact configuration for maximum run life. The bearings have an eccentric locking ring design which eliminates the need for a shrink fit installation. WEAR PLATE REPLACEMENT Baker SPD has incorporated the wear plate into its new Stuffing Box Cover design. However, for preexisting pumps in the field which have a removable wear plate, Baker SPD still offers a separate wear plate as a repair part, thus giving our valued customers the option to choose between the new all in one design or continuing with their existing configuration. INJECTABLE PACKING OPTION In our tireless effort for continuous improvement, Baker SPD is proud to offer an injectable packing option on our pumps. For the 1-7/8 in. MUD HOG pump, this option comes with a modified shaft comprising of a 17-4PH sleeve, shrink fitted onto the fluid end of the shaft. The packing itself is a mixture of non hazardous, high tech fibers and lubricants, which eliminate the need for external lubrication during operation. The injectable packing thus provides a leak free and cheaper alternative to mechanical seals and a more maintenance friendly substitute for the conventional packing rings. The packing can be installed initially by conventional means but can then be easily replenished using a hydraulic hand gun, even during pump operation. Ask your nearest Baker SPD Customer Representative for more information about this exciting product. 6 Baker SPD Centrifugal Pump, The MUD HOG

CENTRIFUGAL PUMP PARTS Baker SPD CENTRIFUGAL PUMP PARTS (CONTINUED) CENTRIFUGAL PUMP LABYRINTH SEALS The Labyrinth Seal or Isolator is a two-piece device used to isolate the Bearings from harmful contaminants, while keeping the Bearings lubricated. Labyrinth Seals use two different components; a rotor and a stator. The rotor is attached to the shaft through a ring and rotates with it, thus decreasing shaft wear. The stator portion of the Labyrinth Seal is stationary and press fit into the Housing. These two pieces lock with an O-ring to form a single working unit. This configuration, while turning, is free from mechanical contact. The Labyrinth Seals are abrasion and corrosion resistant for longer life. CENTRIFUGAL PUMP FRAME The MUD HOG's frame is made from cast iron for strength and durability. The frame has been designed to withstand high piping loads that can adversely affect bearing life. The MUD HOG frame is built to handle various applications and working conditions. MECHANICAL SEALS Mechanical Seals are available for the 1-7/8 in. Centrifugal Pump. However, there is a shaft failure history of the mechanical seal configuration, caused by the inherent bending and vibration that come with a smaller diameter shaft. That is why mechanical seals are not recommended on this pump. Assemblies with Mechanical Seals are NOT warranted. STUFFING BOX BOLTS Two Stuffing Box Bolts are set up 180 degrees apart to hold the Stuffing Box in place. The positioning of the bolts allows the Casing to be replaced without interfering with the Stuffing Box or hampering removal of the Casing. JACK BOLTS The MUD HOG uses two [2] 3/4 in. stainless steel Jack Bolts to assist in the replacement of the Casing. There is a build up of material between the Casing and Stuffing Box during normal operation. This build up can make it difficult to remove the Casing. Conventional pry bars, crow bars and other tools do not distribute an even force and may cause bending. The Jack Bolts allow an even distribution of pressure to the Casing for ease in removal. STAINLESS STEEL CASING NUTS Casing replacement has been made easier by utilizing stainless steel Casing Nuts. Stainless steel is more corrosion resistant than conventional steel. The use of stainless steel material minimizes the need for frequent replacement of the Casing Nuts which are otherwise worn out by rust and/or removal tools. GENERAL INFORMATION 7

Baker SPD NOTES 24

PUMP SIZING Baker SPD HOW TO SELECT YOUR BAKER CENTRIFUGAL PUMP 1. Before sizing your Baker pump, one needs to know the following: 1.1 The pump speed which depends on the kind of drive that will be coupled to the pump, (i.e., 3500, 1750 or 1150 RPM for 60 Hz motor or 3000, 1500 or 1000 RPM for 50 Hz motor). 1.2 The Total Head (TH) required which is the summation of Vertical elevation Head (H e ), and Friction head (H f ), (i.e., TH = H e + H f + any head required at of the end of piping). Use negative suction head when the source of supply is above the pump. 1.3 The flow requirement in GPM or (m 3 /hr). 1.4 The specific gravity of the fluid or weight of the fluid to be pumped, such as the mud weight, in lb/gal. 2. After you get all of the above data, refer to the Baker pump curves and obtain the following information. 2.1 Find the required flow rate on the bottom or top scale, depending on whether you want to measure your Flow rate in GPM or (m 3 /hr), respectively, and draw a straight line up or down. 2.2 Find the Total Differential Head at the left or right hand scale, depending on whether you want to measure your Total Differential Head in Feet or (meters), respectively, and draw a straight line to the right or left. 2.3 Locate the intersection of the above two lines and pick the nearest larger Impeller size. For speeds below 2,900 RPM select Impeller size to next larger 1/4 in. diameter and for speeds above 2900 RPM select Impeller to next larger 1/8 in. diameter. Also a set of horsepower lines gives you the horsepower requirement for pumping water. It is best to choose a motor size larger than the minimum required. If you pump fluid other than water, you have to adjust the required HP (kw) by multiplying the specific gravity to the HP (kw) rating based on water. 3. NPSH Net Positive Suction Head means the useful pressure existing at the inlet of the pump to push the liquid into the impeller vanes. It is measured in feet (meters) of Head and is called NPSH Available (NPSH A ). NPSH Required (NPSH R ) is read from the pump curve at the designed pump impeller RPM and flow rate. NPSH on the curve is the minimum NPSH that will prevent vapor bubbles from forming and causing cavitation. A number of rigs run into NPSH problems which are due in part to high mud temperatures and poor suction design. That is why it is very important to check your Net Positive Suction Head (NPSH). PUMP SIZING NPSH A = H a ± H e - H f - H vp Where: H a = atmospheric head (ft) H e = elevation head (ft) H f = friction head (ft) H vp = Vapor pressure of fluid at pumping temperature (ft). Refer to Page 29. The NPSH R as shown on curves is the minimum NPSH required by pumps. If the NPSH A is larger than NPSH R ; the pump is all right. If the NPSH A is less than NPSH R, then the pump will cavitate. In such a case, some or all of the following changes to the suction conditions might be necessary: 1. Reduce flow rate 2. Increase suction pipe size 3. Lower pump speed 25

Baker SPD PUMP SIZING 4. Formulae: 4.1 To Convert Head in Feet to Pressure in Pounds Per Square Inch Feet of Head x Specific Gravity 2.31 = PSIG 4.2 To Convert Pressure in Pounds Per Square Inch (PSI) to Head in Feet PSIG x 2.31 Specific Gravity = Feet of Head 4.3 Specific Gravity of Mud = Mud Weight (lb/gal) 8.34 4.4 HP required = Curve HP x specific gravity kw required = Curve kw x specific gravity 5. Pump Terms 5.3 Pressure of Head in Feet (meters) When the pump is running, pressure will build up. Pressure developed by the Centrifugal Pump is always specified as Head in Feet or (meters) of liquid. The relation between PSI and head is shown in 4.1-4.2. 5.4 Centrifugal Pump Rotation You have to stand at the drive end to determine the pump rotation. A right-hand rotation pump turns clockwise looking from the motor end. The MUD HOG 1-7/8 in. has a right-hand rotation.

MAINTENANCE MANUAL Baker SPD INSTALLATION, OPERATION AND MAINTENANCE MANUAL FOR BAKER SPD MUD HOG 1-7/8 IN. CENTRIFUGAL PUMPS MAINTENANCE MANUAL 47

Baker SPD MAINTENANCE MANUAL INTRODUCTION This manual contains instructions for the installation, operation, and maintenance of the Baker SPD MUD HOG 1-7/8 in. Centrifugal Pump. After going through this manual, if you feel that some of your questions or situations that you are dealing with, have not been addressed, please contact your local Baker SPD Distributor or Salesman for further assistance. Baker SPD's MUD HOG 1-7/8 in. is a pump designed to replace some older and existing 1-7/8 in. pumps, with a similar but superior product. We have designed this pump keeping in mind a longer life, reliability and easier maintenance. Some of its outstanding features that contribute towards its popularity and success are: 1. Stainless steel shaft 2. Stainless steel casing nuts 3. Grease or Oil lubricated bearings 4. Leakage and contamination prevention through labyrinth seals 5. Stainless Steel Jack Bolts for easy removal of casing It is very important to closely follow proper installation, operation and maintenance guidelines in order to ensure a smooth and efficient pumping operation and longer equipment life. GENERAL INSTRUCTIONS 1. The motor/driver must operate the pump in a manner that the rotation of the pump impeller when viewed from the suction (front) side of the pump is COUNTER-CLOCKWISE. The pump must not be operated in the reverse direction if damage to the pump is to be avoided. 2. The suction and discharge valves must not be completely closed when operating the pump. 3. The packing should be adjusted in a manner that a small amount of leakage remains for lubrication and cooling purposes. 4. For drilling mud operations, care must be taken to prevent seepage from the packing to dry out and coagulate in the areas of the inboard labyrinth seal and the slinger. 5. Do not operate the pump outside its designed performance envelope. SECTION A: INSTALLATION Compatibility The MUD HOG 1-7/8 in. has been designed to ensure that it can replace existing pumps of the same nominal size. To this end, its mounting and overall dimensions have been selected to match up to the existing bases, piping, couplings etc. Location To eliminate the need for priming, the pump suction should be at a lower level than the level of the liquid in the supply tank/reservoir. Foundation It is recommended to pour a concrete foundation on a solid base and it should be big enough to support the whole pump unit. The rigidity of the base plate will play an important role in damping out structural vibrations. The foundation must be thick enough to adequately support the unit. Refer to Hydraulic Institute's Standard ANSI/HI 1.4-2000 for guidelines on this subject. Care must be taken to level the base plate in a horizontal position. Also, when the application dictates the use of a fabricated base, the foundation design must account for it properly, so that it can effectively dampen the resulting resonant vibrations. Alignment For any rotating machinery, the alignment of power transmitting and power consuming parts is critical for its safe and long lasting service. Even if the motor and the pump were aligned before shipping, it is very important to check the alignment after installation to ensure that the arrangement has not moved during transportation or handling. We cannot overemphasize proper alignment since it can mean the difference between a smooth and long lasting pump operation as opposed to high vibrations and even failure of bearings, coupling, pump or the motor. It should be noted that one must not try to align the pump and the motor until its flange and mounting bolts have been tightened. To perform the coupling alignment with dial indicators, which are the instruments of choice for such procedures, the dial indicator is attached to one coupling half with the indicator dial button resting on the outside diameter (OD) of the other coupling half. This will give the offset misalignment between the two shafts. In order to find out the angular misalignment, let the dial indicator button ride on the face of the other coupling half, instead of its OD. A TIR of 0.005" or less is usually considered acceptable by most manufacturers. If the TIR is more than that, it can be adjusted by loosening the pump or driver mounting bolts, adding or removing shims accordingly and then tightening down the bolts again. See figures 1 and 2 below. 48

MAINTENANCE MANUAL Baker SPD 1/64 in. Maximum Gap Figure 1: Offset Alignment with a Dial Indicator Figure 4: Angular Alignment with a Straight Edge More information on coupling alignment can be found in the Hydraulic Institute's Standard ANSI/HI 1.4-2000. Piping Figure 2: Angular Alignment with a Dial Indicator For situations where a dial indicator is not available, one can use a straight edge to perform a reasonable alignment. This method works better when the coupling has a rubber or a flexible drive element. To check for offset misalignment, place the straight edge on the OD of the couplings. If they are aligned there will not be any gaps under the straight edge. A max gap of 1/64 in. is allowed. This procedure should be repeated for at least one more location on the circumference of the coupling 90 degrees from the first position. To check for angular misalignment, the two coupling mating faces should not have a variation in the gap, all around the faces. A maximum variation of 1/64 in. is permissible. See figures 3 and 4 below. 1/64 in. Maximum Gap Figure 3: Offset Alignment with a Straight Edge It is important that the piping should line up to the pump without it having to be drawn closer by tightening the companion flange bolts. Also, the pump should not have to support the weight of the piping. For this to happen, it is better to have the piping anchored independently but as close to the pump as possible. It should also be pointed out that the piping should not be connected to the pump until the grout has hardened and after the motor and pump mounting bolts have been tightened. Suction Piping Suction piping can not only play a critical role in causing vibration and cavitation in centrifugal pumps, but can also be responsible for causing packing and mechanical seal failures as well as putting extreme loads on the bearings. It is therefore very important that the size of the suction piping be at least the same or larger than the suction port of the pump. To eliminate air pockets in the suction line, it is beneficial for the suction line to have a gradual slope down to the supply tank or source. It is recommended that the flow through the pump should not be controlled by adjusting a valve in the suction line. However, this does not preclude the use of a suction line shut off valve to be used when the pump has to be inspected or removed for maintenance purposes. In order to have a relatively turbulence free flow into the pump, it is good practice to have a straight length of pipe, at least twice its diameter in length e.g., a 6-inch suction pipe should have at least one foot of straight pipe just before the pump. In situations which might require a flexible hose to be used in the suction line, it is imperative that such a 49 MAINTENANCE MANUAL

Baker SPD MAINTENANCE MANUAL flexible hose be of the non-collapsing type, since it is not uncommon to have suction pressures which are below atmospheric pressure. In such a scenario, there is a real possibility of starving the pump and thus causing it to overheat. Discharge Piping Like the suction piping, a shut off valve should be used in the discharge piping as well, to enable the removal of the pump for maintenance purposes. A throttle valve can be used in the discharge line to operate the pump at it is design point, if the exact operating conditions are not known. In case of a closed pressurized loop, it is necessary to have a check valve between the pump and the throttle valve, to prevent the product from flowing back through the pump. In the absence of the check valve, such a circumstance can cause the impeller to come loose and cause damage to the pump and also result in leakage beneath the shaft sleeve. SECTION B: PREPARATION FOR OPERATION Before starting the pump, it is good practice to always go through the following simple checks; 1. Check for impeller's free rotation by turning the shaft by hand. 2. Make sure that the suction line and the pump are full of fluid and that the suction valve is fully open. 3. Slightly open the discharge valve and then open it fully once the pump is running. Preliminary Lubrication Our standard pumps come pre lubricated with grease (oil lubrication is available as an option). The operators/customers do not have to worry about lubricating the pump for the first year of operation. At that time, the pump can be lubricated through the outboard and inboard bearing cover lubrication fittings. Usually, labyrinth seals are provided at both bearing ends, and they serve to keep the temperature from rising, by also acting as vents. But in cases where the labyrinth seals are not provided, air vent is used. The air vent must be kept clean. Mechanical Seal Pumps It is vital that these pumps are never started dry otherwise it will cause irreparable damage to the seal faces. The factory installs and adjusts the mechanical seals before shipping the pumps. The seal models currently being provided with the MUD HOG 1-7/8 in. do not require external flush. Pumps with mechanical seals come with 3 rings of backup packing which should be kept completely loose until a seal failure occurs. Only then should they be tightened down to prevent leakage. Packed Pumps When starting packed pumps, the packing should be loose and the packing gland nuts should only be hand tight. Once the pump starts running, slowly tighten the packing down. Make sure that there is some leakage through the packing, otherwise it will overheat and fail. If outside flushing is required on either pump models, the flush lines should be connected and checked for flow through them, before starting the pump Pump Rotation The direction of rotation of the pump should always be checked only when the motor is uncoupled from the pump. Once the direction of rotation of the motor shaft has been ascertained, the pump can be coupled with the motor. Pump Priming To prevent damage to the mechanical seals or packing, there must be liquid in the suction line and the casing, before the pump is started. Fill the suction line with the liquid and vent out any air that might be present in the line. The discharge valve should be barely open when the pump is started and only after the flow and pressure have stabilized that it should be adjusted to the required flow conditions. If the pressure fails to build, close the discharge valve and then reopen it to build discharge pressure. If flow difficulties continue, it may be an indication of improper installation or pump selection. Operators must not run the pump with the suction valve closed under any circumstances, as it will immediately overheat the pump and cause major damage to various components. Also, running the pump with the discharge valve closed should be allowed only for short durations as the energy being imparted to the pumped product by the impeller, will raise the temperature. If for some reason there is a need to keep the discharge valve closed for an extended length of time, then it is recommended to run a small (Ø0.25"or Ø0.50") line, starting 50

MAINTENANCE MANUAL Baker SPD between the pump and the discharge valve and going back to the fluid supply tank. SECTION C: OPERATION Operating Condition Envelope This section only applies to pumps which do not have any external insulation and are exposed to the room temperature. The maximum safe working pressure for cast iron is 175 psig at 150 F or 150 psig at 250 F. The conditions in between can be accordingly calculated. Whenever a high temperature (150 F plus) fluid is being pumped, cooling water should be passed not only through the lantern ring but also over the exposed shaft, so as to dissipate the heat being generated at the labyrinth seal or lip seal and the bearings. Documentation It is always helpful to maintain a documentation history of the pump as it can improve our response time to help you. To this end, we provide a nameplate on each pump frame which contains some information which can help us identify the pump quickly. But in addition to that, it would be helpful to keep a record of the following information; 1. Motor horsepower 2. Operation frequency 3. Maintenance records and pertinent information on any replacement parts. Lubrication Your MUD HOG comes lubricated with grease when it is shipped from the factory and it does not need to be lubricated more than once per year. The recommended grease is Lubri Plate 1200-2. When using different types of grease, care should be taken to use only those types of grease which are well suited to operate with each other. Oil Lubrication for Bearings Oil lubrication for bearings is available as an option but the pumps must be mounted in a horizontal position for oil lubricated pumps to work. This option is typically exercised when it is desired to lower the bearing temperature and hence reduce its wear. It is recommended to use 10W30-non detergent motor oil. The oil can be filled through the hole provided on the top of the bearing frame. After removing the plug provided in the side of the frame, oil should be added from the top until it starts to flow out from the side hole. This will indicate that the level of oil is correct. Adding more oil than recommended can actually be harmful to the pump. Grease Lubrication for Bearings The outboard and inboard bearing covers are provided with a grease fitting. It is recommended to add five shots of grease through the grease port at least once every six months, after the first year of service. Grease Fitting Figure 5: Outboard and Inboard Bearing Covers with Grease Fitting Grease Lubrication for Packing For packed pumps, the stuffing box cover comes with a drilled hole for lubricating the packing rings. It is fitted with a grease fitting. It is recommended to lubricate the packing rings at least once a day. Baker SPD offers an optional self lubricating mechanism which only needs to be filled from time to time. Grease should be added while turning the shaft. A good indication of the sufficient grease in the packing is that it will start to come out around the packing gland. If the packing rings are worn and/or the leakage is deemed excessive, a more viscous variety of grease like the ones used in water pumps should be used rather than the general purpose grease. Water Lubrication for Packing It is recommended that whenever drilling mud is being pumped, water should be fed to the packing through the lantern ring, not only for lubrication purposes but also to prevent fluid being pumped from coming through the packing rings. Such fluids can reduce the life of the packing as well as cause abrasion of the shaft. MAINTENANCE MANUAL 51

Baker SPD MAINTENANCE MANUAL SECTION D: MAINTENANCE Refer to Figures 6-1 through 6-4 on Pages 70 and 71. Disassembly Before starting any disassembly, ensure that the pump is not running and that the coupling between the motor and the pump is disconnected. Next step should be to drain the casing and disengage the suction and discharge piping from the pump casing. If feasible and preferable, remove the pump completely away from the system to a more accessible location. The fluid end components can now be disassembled according to the following procedure: 1. Remove the Packing Gland Halves (30) by loosening the Packing Gland Nuts (29) and then swinging the Packing Gland Bolts (29) to the side. 2. Remove the Casing (16) after removing the Casing Nuts (20). 3. Now loosen the bolts on both the inside and outside Bearing Covers (6). The Bearing Covers should be slid along the shaft to expose the Bearings (10a) and their Bearing Locks (10b). 4. In order to remove the Bearings (10a), the Bearing Lock Set Screw (10c) should be loosened. Next strike the Bearing Lock at the hole provided diametrically opposite to the hole for the Bearing Lock Set Screw, with the help of a thin brass rod (or a punch) and a hammer. The Bearing Lock (10b) should be struck so that it rotates in a direction opposite to the normal operation of the Shaft (11). The Bearing should become loose after a quarter revolution of the Bearing Lock (10b). Remember to remove any burrs on the Shaft caused by the Bearing Lock Set Screw, before attempting to slide the Shaft through the Bearings. 5. The Impeller Nuts (21) on the Impeller (23) should be removed along with the Impeller Washer (22). The Impeller can now easily slide off the Shaft (11). 6. By removing the Shaft (11) from the Frame (1), the two [2] Bearings (10) and the two Bearing Covers (6), with attached Labyrinth Seals (5), become free. The Bearings can be removed from the Frame by lightly tapping them, preferably with a piece of wood. 7. Remove the Bolts (27) and the Washer (26) for the Stuffing Box Cover (25). The Stuffing Box Cover can now be removed from the Frame (1). Remove the Packing Rings (28a) and the Lantern Ring (28b) from the Stuffing Box Cover. Inspection In general, whenever disassembling a pump, always clean the grooves for the O-rings, surfaces of the gaskets, threads and bearings. Impeller: Short of unavailability of new ones, it is always good practice to replace all the gaskets and O-rings during disassembly. Shaft and Shaft Sleeve (Optional): A maximum run out of 0.002 is allowed on the Shaft and the Shaft threads must be in a good condition. The bearing seating surfaces have to be smooth and free of scratches. If any of the above does not seem to be in good condition, the shaft should be replaced. Similarly the surface of the optional sleeve should be checked for grooves and be replaced if necessary. Mechanical Seal: To prevent excessive leakage, the seal faces, gaskets and shaft sealing members must be checked for their condition and replaced if necessary. Ball Bearings: It is important that the bearings rolling elements be smooth and not worn out. If the bearings make noise when rotated, it is time to replace them. New bearings should not be unpacked until it is time to install them. Gaskets and O-rings: Short of unavailability of new ones, it is always good practice to replace all the gaskets and O-rings after disassembly. Assembly It is good practice to always use new gaskets and O- rings even when reassembling an old pump. The following procedure should be followed when assembling a 1-7/8 in. MUD HOG : 1. Mount the two [2] Bearings (10a) in the inboard and outboard recesses of the Frame (1). 2. Slip the Impeller (23) with the Impeller Key (13), on to the Shaft (11). Now thread on and tighten the Nuts (21) onto the Shaft after installing the Washer (22). 3. Install the Bearing Cover Gaskets (9) on the Bearing Covers (6) by using a small amount of grease to keep them in place. 4. Install the Labyrinth Seals (5) in the Bearing Covers (6). 5. Install the Stuffing Box Cover (25) in the Frame (1) with the help of the two [2] Stuffing Box Cover 52

MAINTENANCE MANUAL Baker SPD Bolts (27) and the corresponding Lock Washers (26). 6. Pass the Shaft (11) through the Stuffing Box Cover (25) bore and then slip a Bearing Cover (6) with the Bearing Cover Gasket (9) and then the Bearing Lock (AB), on to the Shaft, in the specified order. 7. Now slide the Shaft (11) into the Frame (1). When the Shaft comes out through the Outboard bearing (10a), slip the Bearing Lock (10b) and the other Bearing Cover (6) with the Bearing Cover Gasket (9), onto the Shaft. 8. After ensuring that the Outboard Bearing (10a) is pressed against the shoulder in the Frame (1) recess, push the Impeller (23) towards the Frame until there is only a 0.075" gap between the back vanes of the Impeller and the front (wear) surface of the Stuffing Box Cover (25). 9. Once again, ensure that the outboard Bearing (10a) is fully pressed against the recess shoulder in the Frame (1). Then turn the Bearing Lock (10b) in the direction of rotation of the Shaft (11) to lock the Bearing in place. 10. Now tighten the Bearing Lock Set Screw (10c). 11. Push the Inboard Bearing (10a) against the recess shoulder and then pull it back out about 0.06" to allow for axial expansion due to temperature variation. The Bearing Lock (10b) on the Inboard Bearing can now be turned in the direction of rotation of the shaft to lock it in place. 12. Tighten the Bearing Lock Set Screw (10c). 13. Both the Bearing Covers (9) can now be tightened into place with the help of the Bearing Cover Bolts (8). 14. Drive the Casing Studs (19) into the Casing (16) and then install the Casing on the Frame (1). Make sure that the Casing has the Casing Gasket (18) installed in it. Tighten the Casing Stud Nuts (20) by applying 140 ft-lb of torque on the nuts. 15. The Impeller Front Clearance should now be checked. It should be about 0.025". Stuffing Box and Components 1. The packing rings (27) will usually be either of the Teflon or King type. 2. Make sure that the Stuffing Box Cover ID is clean, smooth and free of any burrs and scratches. 3. Grease should be applied to all the packing rings. 4. Insert three [3] packing rings, taking care to align skives in the rings 180 degree apart and the skive on the first ring on the bottom side. In case of King packing, install the rings such that their lips are facing the suction side of the pump. 5. The lantern ring should be installed next, making sure that the split in the lantern ring is oriented vertically. 6. The remaining two [2] rings should now be installed such that the skive in the last ring comes on the bottom side. However, in case of King Packing, the final King ring should be mounted such that the lip is facing the coupling end and it's skive is at the top. The last square ring of packing can then be installed with the skive pointing downwards. 7. The Packing Gland Halves (30) should now be put it place and pressed in slightly by tightening the Packing Gland Bolts (29). Note: Since packing can burn easily if it is too tight around the rotating element, so once the packing has been pushed and seated in, the Packing Gland Bolts (29) can be loosened and then hand tightened only. This is the recommended condition to start the pump in. Once the pump has been running for a little while, one should go back in and tighten the Packing Gland Bolts so that there is only 10-15 drops of leakage per minute. It is important to remember that if a Packing Ring does burn, it will never seal properly again GENERAL OPERATING AND STORAGE INSTRUCTIONS Some of the important factors to watch for, while operating a pump, are: 1. The packing should not be over tightened as it will become hard and brittle and will fail to perform its function. But it is also important, especially when a water flush system is being employed to lubricate the packing rings, that rings be not too loose. That can result in flush water seeping into the drilling mud and changing its density. This situation can also arise due to a gap between the shaft and the packing, which results due to the whirling of the shaft about its own axis during pump operation and thus causing deformation of the packing. This predicament can be solved by either manually shutting off the water whenever the pump is not running or installing a solenoid valve for this purpose. 2. Another factor that should be controlled to limit the amount of water from getting into the drilling mud is the pressure of water for the flush system. Pressure as small as 5 psi is usually enough to provide the required lubrication for the packing rings. A pressure regulator should be preferably incorporated into the water flush system for this purpose. 3. Bearing failure is the biggest contributor to pump maintenance costs. So it is imperative that care be taken not to run the pump if the bearing condition 53 MAINTENANCE MANUAL

Baker SPD MAINTENANCE MANUAL is suspect. A quick check that can be easily performed is to estimate the temperature of the pump housing by placing a hand on it. Usually if a person can comfortably keep his/her hand on the pump housing for a little while then the temperature is not more than 150 F. If the temperature seems more than that, then the chances are either, that the bearings have started to fail or that there is a lack of lubrication for them. Replacing bearings at this stage is more cost effective than waiting longer and then having to replace a number of other parts as well. 4. One of the most common reasons for bearing failure is misalignment between the pump and the motor. Hence it is very important to check alignment not only before starting the pump for the first time but to also do it periodically. 5. Care should be taken not to increase the suction line velocity beyond 10 ft/sec because that can result in turbulence as well as cavitation. These conditions will adversely affect the efficiency and the life of the pump, respectively 6. Perhaps the most important factor for predictable pump performance is the Available Net Positive Suction Head (NPSHA). Simply put, it means that the height of the fluid in the supply tank above the suction level of the pump should be enough to prevent the fluid from entering the pump at a pressure which is below its vapor pressure at that temperature. If such flow conditions cannot be avoided, cavitation occurs which is the boiling of that fluid at the operating temperature and then the bubbles being created during that boiling process implode and damage the various pump and system components. Thus to prolong the life of the pump always ensure that the pump has the recommended NPSHA. 7. In case of indoor storage, it is desirable to avoid temperature extremes, excessive moisture and vibrations. 8. It should be standard procedure to check the resistivity of motor windings at the time of placing them in storage and again when it is time to take the motor out and use it. A difference of more than 50% necessitates the drying of these windings before the pumps operation. 9. Whenever pulling the pump and the motor out of storage, it is recommended to remove all the old grease from the bearings and replenish them with fresh new grease. 10. It is also recommended to manually turn the shafts of the motor and the pump at least once every two months. 11. If the pumps are to be stored outdoors for an extended period of time, it is good practice to properly seal off the suction and discharge openings, to prevent rust from attacking the pump casing and impeller. Note: A written record of all the storage procedure and actions should be maintained. 54
