5 1 - Introduction 1.1 DESCRIPTION The Gamajet PowerFlex is a fluid-driven (turbine-driven) 360 rotary nozzle machine designed for cleaning the interior surfaces of a wide variety of process vessels with a minimum opening of inches (174.7 mm) in diameter for a pin drive machine or inches (98.5 mm) for a clutch machine and the nozzles in the vertical position and inches (97.3mm) for the low profile machine regardless of nozzle position. It is powered entirely by the cleaning solution and it requires no electricity, compressed air or lubricant for operation. The Gamajet PowerFlex is designed for both portable and CIP (Clean In Place) applications. If the Gamajet PowerFlex is permanently mounted inside a tank, we strongly recommend inspecting the unit every few hundred hours of operation. (See Section 3 - Preventative Maintenance for more information.) WARNING: In some conditions, the Gamajet PowerFlex may be allowed to be immersed while left in the tank. It is strongly recommended that you have prior approval from Gamajet Cleaning Systems, Inc. to ensure this will not harm the machine in any way. Failure to comply with this restriction may void the warranty!!! In order to handle the broadest possible range of applications, the stainless steel Gamajet PowerFlex is available with an extensive selection of nozzle sizes, stators (non-rotating turbine), and O-ring materials. The nozzles are available in several interchangeable sizes that range from 1/4 to 3/8. The Gamajet wash cycle time can be adjusted for special applications by changing the stator and/or nozzle size. Interchangeable stators and nozzle sizes are available for either low or high pressures and/or flow rates. The performance capabilities of these options are detailed in Appendix D. A three-view cut sheet of the Gamajet PowerFlex is contained in Appendix A. 1.2 ICONS USED IN THIS MANUAL Warning! - The information associated with this icon could cause damage to the machine, vessel it is contained within, or the operator. Note - A useful piece of information worth remembering. Assembly/Disassembly Tip - The following information is a tip from Gamajet that will aid you in working on the machine. Flow-Thru PowerFlex Owner s Manual v.10/13 1

6 1.3 INSTALLATION OF NEW MACHINES ASSEMBLY Every Gamajet is operationally tested before shipment and is ready to run after unpacking. No assembly is required prior to use. The Gamajet has been configured to meet the operating conditions (at the Gamajet, not at the pump) given to us, e.g. pressure, flow, temperature, cycle time, chemical adders, etc. Note: Any change to the original operating conditions will affect the Gamajet accordingly. WARNING: Do not force Tee Housing, # PF to rotate. Doing so may cause damage to the internal components INLET CONNECTIONS The standard inlet connections for the Gamajet PowerFlex are a 1-1/2 slip-fit or a 1-1/2 Tri- Clover. Others inlets are available. It is recommended that when using the pipe thread the mating male thread should be wrapped with PTFE pipe joint tape prior to mounting. This will minimize any chance of leakage and will make subsequent removal much easier MOUNTING Before mounting the Gamajet PowerFlex, make sure the supply line has been adequately flushed. It can be mounted on a rigid 1-1/2 pipe using appropriate mounting methods. In most applications, the Gamajet PowerFlex will be mounted with the inlet connection pointing up; however, the PowerFlex will function at any orientation. The Gamajet PowerFlex can be suspended from the top of the tank via a flexible hose. The dual nozzle machine is designed to have balanced forces in order to keep it centered even while hanging. We do not, however, recommend attaching the machine to a flexible hose while in the inverted or horizontal orientation. This form of mounting is not rigid and, thus, will not maintain the Gamajet s position in the tank. WARNING: When attaching the Gamajet PowerFlex onto the supply pipe, ALWAYS apply the wrench to the Inlet Collar # PF at the top/inlet of the unit. Never use a wrench on Stem # PF, Tee Housing # PF, or Tee Housing Cap # PF to tighten the unit onto the pipe. Doing so risks internally damaging the machine. Refer to Step 18 in Appendix C for an illustration LOCATION INSIDE TANK Generally, a single Gamajet will be positioned in the approximate center of the vessel in order to equalize the cleaning radius in all directions. Some vessels, however, may have specific cleaning problems such as coils or heavy deposits such as the liquid level line (bathtub ring). In these situations the Gamajet should be located closer to the difficult area for the best cleaning results. Flow-Thru PowerFlex Owner s Manual v.10/13 2

7 Tanks with internal mechanisms or structures such as an agitator shaft, impellers or baffles will require careful positioning to minimize the shadow on areas which do not receive direct jet impact. Sometimes, more than one machine, or, more than one placement of a single machine, may be necessary to avoid shadow problems or striping ENTRY OPENINGS When using the Gamajet PowerFlex, the vessels being cleaned must provide entry openings large enough to avoid interference during insertion and removal. The minimum opening size required for the Gamajet PowerFlex is inches in diameter (98.5 mm) for free-hand installation of a clutch driven machine and the nozzles in the vertical position. For a pin drive machine, the minimum opening size required is inches (174.7 mm). A inches (97.3mm) opening is needed for the low profile version of the PowerFlex regardless of the nozzle position VESSEL DRAINAGE If it is necessary to clean the floor of a vessel, remember that standing liquid will diminish the effectiveness of the Gamajet by covering any soils underneath. Wherever possible, the tank floor should be pitched toward the drain and the drainage opening should be large enough to eliminate or reduce any liquid buildup or puddling. If gravity alone is insufficient, a scavenger or stripper pump should be connected to the drain to suck out the excess wash fluid. In extreme cases, it may be necessary to use smaller nozzles on the Gamajet, or even to operate it intermittently to allow time for draining FILTERS AND STRAINERS All tank cleaning systems should be equipped with a filter or strainer that will trap solids 1/16 and larger, as these will not pass through the Gamajet. These particles can become caught in one of the internal passages of the machine and cause it to stop turning or reduce its cleaning effectiveness due to a loss of flow. It will then be necessary to disassemble the Gamajet and remove the blockage. In recirculated (closed-loop) cleaning or any other application where the cleaning solution may carry abrasive solids in suspension, adequate filtration is a must. These particles can be extremely destructive to the Gamajet, pumps, valves, and other system components. Filters, properly installed and maintained, will more than pay for themselves with lower overall operating costs in these applications. Furthermore, to ensure that clogged filters or strainers are cleaned, we recommend using automatic self-cleaning models CAPACITY OF SUPPLY PUMP The Gamajet PowerFlex can be used with either a centrifugal or positive displacement (constant volume), PD, style pump. In most cases, if the PowerFlex is to be used with a centrifugal pump, the PowerFlex should be configured so that the pump will operate close to its best efficiency point. The end user must, therefore, take all of the plumbing, elevation, and PowerFlex pressure/flow rate requirements into account. If a PD style pump (i.e. piston pump, plunger pump, or mechanical diaphragm pump, etc.) will be supplying the wash fluid to the Gamajet PowerFlex, a different set of rules apply. PD pumps are fixed volume pumps whose flow rate is dependent upon the rotational speed of the pump; the pumps also have a pressure rating which is the maximum operating pressure. Note: Do Flow-Thru PowerFlex Owner s Manual v.10/13 3

8 not confuse the maximum operating pressure of a PD pump with the actual operating pressure, the actual operating pressure is dictated by the fixed flow rate of the pump and the Gamajet PowerFlex / plumbing system. If a PD pump is used, the Gamajet PowerFlex should be sized to, first, match the flow capability of the pump and, second, not exceed the PowerFlex s or pump's maximum operating pressure (taking the pressure rating of the plumbing system into account, also). WARNING: For high-pressure applications (over 150 psig), the pressure of the system must "ramp up" to its operating pressure. If the system experiences a pressure spike or pressure increases at a rate of more than 150 psi per second, the machine may be damaged and parts will wear out prematurely. Damage resulting from this water hammer affect is not covered by the warranty INITIAL STARTUP Every PowerFlex that ships is accompanied by a Birth Certificate. This document indicates how the PowerFlex performed in our testing tank before it shipped based on the operating conditions supplied to Gamajet. To ensure the longest possible life of the PowerFlex, please verify the operating conditions and, most importantly, the machine s cycle time. The cycle time can be measured by, first, picking a fixed point inside of a vessel as a reference and, second, timing how long it takes the same nozzle to pass back over that point in the vessel. (This, naturally, will not be the exact same spot because the spray pattern is indexing.) The measured time in seconds directly corresponds to the machines full cycle time in minutes. In other words, a single 10-second rotation translates to a 10 minute full cycle time. 1.4 SAFETY When a Gamajet is operating, there should be covers over every tank opening. These covers should be sealed well enough to withstand the full force of the jet striking the cover plate. If the cleaning solution were hot, corrosive, or toxic, a leak would present a serious hazard to any personnel in the immediate vicinity or to any exposed electrical equipment. WARNING: Any tank-cleaning machine can develop a static electricity charge while in operation. If the tank being cleaned contains a combustible liquid or vapor having a risk of ignition or explosion, it is imperative to have the Gamajet properly grounded using the provided location on the unit.

Also, for simplicity the 10- prefix to the part number has been eliminated in all of the following instructions. All threaded connections are right hand threads unless otherwise noted INLET COLLAR Step 18 Loosen the Collar Set Screw #150 with a 3/32 Hex Key, minimum 2 turns. Remove the Inlet Collar #108 and Stator #109. WARNING: Hold or turn on Stem. DO NOT hold or turn on Tee Housing or Tee Housing Cap. Doing so will damage the gear train NOZZLE HOUSING Step 17 Unscrew the Nose Plate #106-FT with a 1/2 slotted screwdriver. Pull the Nozzle Housing (Step 15) assembly from the nose of the Tee Housing with the outer Bearing #133-PF-FT. Remove the inner Bearing #133-PF-FT CAP AND GEAR TRAIN Step - 12 Using pliers or a bench vise on the flats of the Cap #102, unthread it from the body (Step 11). WARNING: Hold or turn on Stem. DO NOT hold or turn on Tee Housing or Tee Housing Cap. Doing so may cause damage to the gear train. Flow-Thru PowerFlex Owner s Manual v.10/13 5

10 Pull the Gear Train (Step 6) from the remainder of the body. Two slotted screwdrivers can be placed on either side of the Rotor E-810 and used to lift the gear train out. This is only for leverage and should not be used if the gear train is jammed or stuck inside of the body BODY ASSEMBLY Step - 11 Unthread the Tee Housing Cap #114-PF from the Tee Housing (Step 8). Note: This is a Left Hand thread. Remove the Stem Screws #146 with a 5/32 Hex Key, and Stem Base (Step 9) from the Tee Housing (Step 8). Remove the Tee Housing (Step 8) by pulling it from the Stem (Step 7). The Bearing #131-FT will pull off with the Tee Housing. Remove the lower Bearing #131-FT and Bevel Gear (Step 10). 2.3 INSPECTION AND SERVICE OF COMPONENTS STATOR Step - 18 Inspect the through holes of the Stator #109 to be sure that they are clear COLLAR O-RINGS Step - 12 Inspect the Small and Large Collar O-rings, #7-458 and E-862, for damage (clipped or cut) or deterioration (compression set or hardening) and replace if necessary. Inspect the Collar-Stem O-ring E-863 for damage (clipped or cut) or deterioration (compression set or hardening) and replace if necessary PLANETARY GEAR TRAIN ASSEMBLY General Disassembly and Inspection Steps 4 and 6 In Step 6: Pull the Output Shaft #112-F and the Gearhead Lower Bearing Housing (Step 2) from the Planetary Gearhead (Step 4). Pull off the top of the Planetary Gearhead (Step4) comprised of the Rotor (Step 5), the Input Shaft Bearing Housing (Step 1) and the Input Shaft (Step 3) together. What is left is the cartridge style Gearhead (Step 4). If the gear train O-rings E-175 needs to be replaced, remove them at this time. WARNING: To reduce the likelihood of scratching any sealing surface, use a pick made from brass. Inspect the E-175 for damage (clipped or cut) or deterioration (compression set or hardening) and replace as required Gearhead Internals Steps 4 Flow-Thru PowerFlex Owner s Manual v.10/13 6

11 Tip: To prevent the internal components of the Planetary Gearhead from unexpectedly spilling out, make sure that all steps are done with the input end (the end without the shaft) of the assembly facing up. Using a brass pick or a small screw driver, remove the Internal Retaining Ring E-121 and remove the Top Planetary Large Washer E-170. Remove the internal components of the gearhead. Use caution to ensure that no components get lost during this operation. If the internal components are not easily removed, they can be pushed up from the bottom of the gearhead. Also, the other Internal Retaining Ring E-121 and the Planetary Output Shaft Washer E-140 can be carefully removed and the internal components pushed through. WARNING: If you suspect that the Gearhead requires service, proceed with caution. If at any time you do not feel completely comfortable servicing Gearhead, contact Gamajet Cleaning Systems immediately. Examine the gears of the four different stages for any worn or broken teeth. Also, examine the main internal ring gear for bent or sharp teeth. If any damage is found contact Gamajet immediately. The gears in each level are interchangeable; they all have the same number of teeth Input Shaft and Housings Steps 4 cont. Take the top of the gear train that was removed prior in Step 6. To remove the Rotor E-810, grip the outside of the Rotor with smooth jaw pliers and use a 5/16 socket to remove the Output Pinion Nut The Input Pinion #512 can be gripped, but this is not recommended because of the potential of damage to the gear. Only do this if the gear is worn and is be replaced. Ensure the Carbide E-839, pressed into E-810 (Step 5), protrudes slightly, and is not chipped or cracked. Check for signs of scoring and wear on Input Shaft #822-FT (Step 3). Replace if the coating has been chipped or cracked. The carbide E-839 in the #128-FT should protrude slightly out of the top and the second E-839 should be recessed.052 (Step 1). In addition, its running surfaces should be smooth, flat, and free of chips and cracks Gearhead Lower Bearing Housing and Output Shaft Steps 2 and 6 Inspect the Carbide E-840 in the Gearhead Lower Bearing Housing #129-FT (Step 2). It should be pressed fully into the Gearhead Lower Bearing Housing #129-FT and should not be chipped or cracked. Check for signs of scoring and wear on Transition Output Shaft #112-F. Replace if the coating has been chipped or cracked NOZZLE HOUSING Steps 13 to 15 and 17 Flow-Thru PowerFlex Owner s Manual v.10/13 7

12 Unscrew the Nozzles E-807-PF or #107-LP with pliers and inspect for debris caught on the Stream Straightener #160 or in the nozzle orifice. The inside diameter of E-807-PF or #107-LP must be smooth, round, and free of damage (especially any nicks) for maximum jet impact. Replace worn or oversized nozzles if the original flow rate and pressure are required. Verify the #160 is tight in the bore of the E-807-PF or #107-LP. Inspect the Nozzle Housing Bevel Gear #118 for wear such as sharp/pointed or worn teeth. If it needs to be replaced, remove the Bevel Gear Retaining Ring #119 with a small slotted screwdriver and pry #118 from the Nozzle Housing #105-PF or #105-D-LP. Clean any deposits from #134 and examine for excessive wear. Light scoring is acceptable, but the #134 should be replaced if they are grooved in the bearing contact area. A good maintenance program will require replacing many #134, therefore, it may be worthwhile to make or obtain press tools for pressing #134 out of #105-PF or #105-D-LP. The press tools are available from Gamajet Cleaning Systems. Before installing new #134, clean the housing bores and remove any burrs resulting from #134 removal. Press them in so that their flanges are flush against #105-PF or #105-D-LP. Inspect the Nozzle Housing Bearings #133-PF-FT. Clean any deposits from the exterior of #133-PF-FT and check their fit in the #134. While they should turn freely, #133-PF-FT should be replaced if the thickness of the flange is 0.086, or less, to avoid shortening the life of the Bevel Gears TEE HOUSING AND TEE HOUSING CAP Steps 8, 10 and 11 Check the water outlets on the nose of the Tee Housing #104-PF-FT; they should be free of debris. Inspect the Tee Housing Bearings #131-FT. Clean any deposits from the exterior of #131-FT and check their fit in the Tee Housing Cups #132. While they should turn freely, #131-FT should be replaced if the thickness of the flange is 0.095, or less, to avoid shortening the life of the Bevel Gears. Inspect the Tee Housing Cap O-ring for compression set or deterioration. Replace, if needed. Inspect the Tee Housing Bevel Gear #117 for worn, damaged or sharp/pointed teeth. Ensure that the Pin #164 is pressed firmly into #117. Clean any deposits from #132 and examine for excessive wear. Light scoring is acceptable, but the Cups should be replaced if they are grooved in the bearing contact area. A good maintenance program will require replacing many #132, therefore, it may be worthwhile to make or obtain press tools for pressing #132 out of #104-PF-FT. The press tools are available from Gamajet Cleaning Systems. Before installing new #132, clean the housing bores and remove any burrs resulting from #132 removal. Press them in so that their flanges are flush against #104- PF-FT. Ensure that the Pin #164 is pressed firmly into #104-PF-FT STEM AND STEM BASE Steps 7 and 9 The Pin #164 should be firmly pressed into the #130. Inspect the water outlets of the Stem #103-PF; they should be free of debris. The Pins E-866 and #155 should be firmly pressed into the #103-PF. Flow-Thru PowerFlex Owner s Manual v.10/13 8

13 Check O-ring #147 for signs of damage (clipped or cut), deterioration (compression set or hardening) or wear (flat edge developing or ring has thinned) and replace if necessary CLUTCH TO PIN DRIVE, PIN DRIVE TO CLUTCH Steps 7 The Pin E-866 should not be present in the stem #103-PF if the machine is a clutch machine. In order to make the machine a pin driven machine, simply push a E-866 pin into its hole in the stem #103-PF until it completely stops at the bottom of the hole. The clutch O-ring remains in place. WARNING: Once a machine is made into a pin drive, the Nozzle Housing #105- PF or #105-D-LP will no longer rotate freely. Forcing the Nozzle Housing #105-PF or #105-D-LP to rotate will result in damage to the machine. To make a pin machine into a clutch machine, use a pair of pliers to grip the pin E-866 and pull it out of the stem #103-PF. If the pin cannot be pulled out, use a grinder to grind away the exposed portion of the pin (this method will make it harder to return the machine to a pin drive if desired later). The clutch O-ring should already be installed and will run as a normal clutch machine. 2.4 REASSEMBLY GENERAL NOTES All parts must be cleaned thoroughly before reassembling. Any deposits remaining on the parts can cause difficult disassembly the next time the Gamajet needs to be serviced. Also, it may cause misalignment of parts and the potential for premature failure. Unless otherwise stated, apply a dab of a Teflon-based anti-seize compound to all threads when reassembling; this will prevent galling of threads and ease any future disassembly. To ease installation of all O-rings, they should be lubricated prior to reassembly. Lithium-based grease is acceptable, for Viton O-rings, however, Silicon based lubricant must be used for EP O-rings. Do not lubricate the clutch O-ring #147. Refer to the illustrations in Appendix C for clarification during reassembly GEAR TRAIN Steps 4 and 6 With the empty Planetary Ring Gear #125, replace the Top Planetary Large Washer E-170 and the Internal Retaining Ring E-121 into the top of the ring gear. The top is the end with the 4 holes drilled in the sides. With all the internal components assembled as in Step 4, slide the assembly into the ring gear from the bottom up. The assembly may need to be jiggled or twisted slightly in order to get the gear teeth to line up. Note: Ensure that every Planet Gear #139 has a Planet Gear Washer #896 under it on each post. Replace the Planetary Output Shaft Washer E-140 and the Internal Retaining Ring E-121 on the bottom of the gearhead. This completes the cartridge gearhead assembly. Place the Transition Output Shaft #112-F through the Gearhead Lower Bearing Housing (Step 2) and press the bottom of the gear train assembly firmly onto the bottom of the gearhead. Be sure to align the pin on the Gearhead Lower Bearing Housing with the slot on the outside of the Ring Gear #125. Flow-Thru PowerFlex Owner s Manual v.10/13 9

14 Insert the Input Shaft (Step 3) through the Input Shaft Bearing Housing (Step 1). Put the Rotor (Step 5) over the end of the shaft with the carbides of the Rotor and the Input Shaft Bearing Housing facing each other. Fasten the Rotor Lock Washer and the Output Pinion Nut onto the top of the Input Shaft and tighten with a 5/16 socket wrench. The Rotor E-810 can be held with smooth jaw pliers to keep it from rotating. Do not grip the Input Pinion #512 while tightening the nut because this will cause damage to the gear. Press the top of the gear train assembly firmly onto the top of the gearhead ensuring that the Input Pinion #512 aligns with the top layer of planet gears and the pin on the Input Shaft Bearing Housing (Step 1) is aligned with the slot on the outside of the Planetary Ring Gear # BODY ASSEMBLY Step - 11 Slide the Tee Housing Bevel Gear #117 (Step 10) over the end of the Stem #103-PF (Step 7). Align the hole in the #117 with the Pin E-866. Place the first Tee Housing Bearing #131-FT onto the #103-PF. Push the Tee Housing #104-PF-FT (Step 8) over it until it is fully seated. Install the second bearing #103. Tip: Now, Place the second Tee Housing Bearing #131-FT into Stem Base #130 (Step 9), aligning its hole with the Bearing Locating Pin #164. Now, invert the #104-PF-FT/#103 assembly and place it over #131-FT/#130 assembly. This technique ensures correct alignment of #131 and #164. Apply pressure to #130 to drive it and the #131-FT into the #104-PF-FT. Align the through holes of the #130 with the threaded holes in the top of the #103. Using a 5/32 Hex Key, thread Cap Screws #146 and Lock Washer E-847 into the #103. Tighten in a star pattern. Thread the Tee Housing Cap #114-PF to the end of the #104-PF-FT. Note: This is a Left Hand thread GEAR TRAIN INSTALLATION Step - 12 Insert the Gear Train (Step 6) from section into the Body Assembly (Step 11) of Rotate the Tee Housing #104-PF-FT until the Output Shaft #112-F falls into the slot of the Tee Housing Cap #114-PF. Continue rotating the Tee Housing until the Tapered Pins #155 are between the tabs of the Input Shaft Bearing Housing (Step 1) and the Gear Train (Step 6) is able to be seated fully down. Thread the Cap #102 into the Body Assembly. Be sure to use the flats provided on the #102. Tighten. WARNING: Hold or turn on Stem. DO NOT hold or turn on Tee Housing or Tee Housing Cap. Doing so will damage the gear train NOZZLE HOUSING Step - 17 Place the first Nozzle Housing Bearing #133-PF-FT onto the nose of the Tee Housing #104- PF-FT. Ensure the Pin #164 is aligns with the hole in the #133-PF-FT. Push the Nozzle Housing Assembly (Step 15) onto the nose of the #104-PF-FT. Flow-Thru PowerFlex Owner s Manual v.10/13 10

15 Rotate the Nozzle Housing Assembly slightly to mesh the Bevel Gears #117 and #118. Failure to ensure that the Bevel Gears have properly mated could damage them. Install the outer Bearing #133-PF-FT into the Nose Plate #106-FT (Step 16). Ensure the Pin #164 aligns with the hole in the #133-PF-FT. This will hole the bearing during installation and will keep the hole in the #133-PF-FT bearing to be properly aligned with the pin. Using a ½ slotted screwdriver, screw the #106-FT/#133-PF-FT assembly completely snug COMPLETED ASSEMBLY Step 18 Rotate the Rotor E-810 using a Hex Key, screwdriver or thin rod. It should spin easily and its veins must not strike the walls of the Cap #102. Continue turning the Rotor several dozen times. The Nozzle and Tee Housing will slowly rotate if everything has been assembled correctly. Insert the Stator #109 into the #102. Screw on the Collar #108 (hand-tight only), and tighten the Collar Set Screw #150 with a 3/32 Hex Key. WARNING: Hold or turn on Stem. DO NOT hold or turn on Tee Housing or Tee Housing Cap. Doing so will damage the gear train. Flow-Thru PowerFlex Owner s Manual v.10/13 11

16 3 - Preventive Maintenance Note: A rigorously implemented preventative maintenance program will significantly reduce repair costs over the life of the Gamajet. The foundation of such a program is regularly scheduled inspections to discover and replace worn or damaged parts before they can cause the failure of other, more costly, components. The inspection intervals required will depend on the severity of the application, but a complete internal inspection at 100 hours of operation is recommended initially. Note: Part numbers appearing below may be used to identify parts in Appendix C. 3.1 STORAGE The Gamajet should be washed out with clean water after each use to remove any foreign material or soft substances left in the machine that may harden during storage and cause the Gamajet to seize or lock up. A clean water rinse through the Gamajet will also wash out any residues of chemical cleaners or recirculated wash water that could adversely affect the seals and O-rings during prolonged contact in storage. The best position to store the Gamajet is to stand it up with the inlet connection facing down. 3.2 EXTERNAL INSPECTION INTERVALS Before every shift, the Stator # 109 and the Nozzles E-807-PF or #107-LP should be inspected for debris. Examine the #109 by loosening the Collar Set Screw #150, while holding on the flats of the Cap #102 and remove the main section of the machine from the Collar #108. Look into each Nozzle for signs of debris or build-up. 3.3 INTERNAL INSPECTION INTERVALS An interval of 100 hours is recommended initially. If all of the components are found to be in acceptable condition after the first 100 hours, the Gamajet may then be inspected and routine preventive maintenance should be performed every 600 to 800 hours of operation, depending on the severity of use. 3.4 TIPS All the Bearings, Bushings and O-rings are wear parts. Ideally, they should all be replaced, as a group, every 600 to 800 hours of operation, depending on the severity of use. If just one Bearing or Seal is worn or damaged, replace both it and its mate, not just the worn or damaged part. Verify that the mating cups #132 and #134 are not scored. Replacing new bearings and seals in scored cups may prematurely wear the new bearings and may cause premature failure of the bearings and seals. Flow-Thru PowerFlex Owner s Manual v.10/13 12

18 4.1.2 INSUFFICIENT FLOW The Gamajet was configured to meet certain operating conditions outlined at the time of the initial sale, such as flow rate (GPM), pressure (PSI), temperature, chemical content of the wash fluid, cycle time, etc. If the Nozzle size is too small and/or the opening at the bottom of the Stator is too large, the Tee Housing will not turn. Look for restrictions in the fluid supply such as a clogged filter, kinked hose, or deposits in the piping TIGHT CLEARANCES A recently overhauled Gamajet PowerFlex may fail to operate when first returned to service. If the machine seems otherwise fine, try running it with at least one Nozzle removed. The reduction in pressure and additional flow will invariably be enough to overcome the extra resistance of new Bearings and Seals. Twenty minutes of operation should loosen the machine to run normally with the Nozzles reinstalled DEBRIS INSIDE Loosen the Collar Set Screw #150, remove the Collar #108, and then lift out the Stator #109. Look for and remove any debris caught in the Stator and the vanes of the Rotor E-810. Remove any material wound around the Input Shaft #822-FT. In addition, check for any debris caught in the outlet holes of the Stem #103-PF, the nose of the Tee Housing #104-PF-FT, the Nozzle Housing #105-PF or #105-D-LP, and the Nozzles E-807-PF or #107-LP. 4.2 CLEANING SOLUTION LEAKAGE The Gamajet PowerFlex is a self-flushing machine and thus has up to 15% leakage designed into the machine. Excessive leakage may indicate a larger issue WORN BEARINGS & SEALS Excessive leakage from the Tee Housing or Nozzle Housing usually indicates worn Housing Bearings and Seals. Inspect them for wear (sealing lips are worn to a smooth surface) or damaged lips or loss of spring tension (indicated by excessive dry deposits of dirty or abrasive cleaning solution on the spring), and replace as required WORN HOUSING CUPS Inspect the Housing Cups #134 and #132 for excessive wear (grooved or scored). Replace any that show distinct grooves WORN COLLAR O-RINGS Severe leakage between the Collar #108 and Cap #102 may indicate worn or damaged Collar O- rings and E-862. Remove the Collar as described in Section 2, and inspect the O-rings for signs of damage or wear WORN CLUTCH O-RING Severe leakage above the Tee Housing may be the result of excess wear on the Clutch O-ring #147. There will be leakage through this point regardless due to the normal clutch operation, Flow-Thru PowerFlex Owner s Manual v.10/13 14

19 but severe leakage is not ordinary. Remove the Tee Housing as described in the general disassembly instructions and inspect the Clutch O-ring #147 for damage or wear. 4.3 POOR CLEANING PERFORMANCE INADEQUATE FLOW AND PRESSURE Check the pressure at the Gamajet inlet under actual operating conditions. The supply piping and hoses must be large enough to handle the flow rate required for the nozzle size being used to ensure adequate pressure. Insufficient pressure may also result from line losses when the machine is far from the pump. If this is the case, the line size must be increased accordingly for long runs. Although the Gamajet will rotate at low flow rates, effective cleaning may require considerably more flow. Proper mechanical operation (the unit turns) is NOT the same thing as effective cleaning (the soils have been removed)! Contact Gamajet if assistance is required CHEMICAL CONCENTRATION AND TEMPERATURE Verify that the cleaning solution is the correct compound and in the concentration needed for the deposit being cleaned. If heating is necessary, also check that the solution is at the proper temperature PLUGGED NOZZLES Unscrew the Nozzles E-807-PF or #107-LP and inspect for any debris SLOW OR NO ROTATION OF THE HOUSINGS This will result in partial or erratic washing coverage. Refer to previous sections for more information GAMAJET CONFIGURATION Determine if the deposit being cleaned requires greater jet impact or longer jet dwell time (slower rotation) for more thorough scrubbing. Confirm that the Gamajet nozzle size, turbine, and gearing are correct for the specific application. Refer to the machine s Birth Certificate for specific information regarding its configuration. Contact a Gamajet representative if assistance is required INADEQUATE DRAINAGE Ensure that the vessel drains the effluent (used wash fluid) as fast as it s being sprayed in through the Gamajet. The floor of the vessel should be sloped or pitched toward the drain and the drainage opening should be large enough to gravity-drain the effluent from the vessel. If you still have puddling (build-up of the wash fluid so it covers the floor and shields the residues underneath), use some form of pump to remove the effluent.
