PROPER PUMP SELECTION Careful selection and installation of the correct GREENLINE Premium Slurry Pump will result in a unit that will provide long-lasting and dependable service. Selecting a pump with excessive pressure capability means extra horsepower expense. Premium Slurry pumps have much different horsepower input characteristics than positive displacement pumps. However, if the pressure requirements on the discharge side are indefinite, or if for some reason the discharge pressure is much lower than expected, the pump will handle considerably more fluid and require more horsepower than originally selected to drive the pump. A valve or flow restriction will then be required to increase the discharge pressure and reduce the horsepower needed to drive the pump. To assure proper pump selection, the following information is required: 1. Suction conditions: A. Size of suction piping B. Length of suction line C. Flooded suction (positive) D. Suction lift (negative) 2. Total discharge head required. 3. Rate of flow desired. 4. Type of driver desired and RPM (electric motor or engine) 5. Specific gravity or weight of fluid to be pumped. 6. Temperature of fluid. 7. Any information available as to the corrosiveness or abrasiveness of the fluid to be handled. Once this information is obtained it is used to calculate: GPM = (Rate of flow desired) HD. FT. = (Total required head in feet) SP. GR. = (Specific gravity of fluid) PUMP SIZE AND HORSEPOWER SELECTION FROM PERFORMANCE CURVES Using the desired GPM and head feet, find the pump size and speed by looking at the performance curves. Make the desired operating point on the performance curve. This operating point may appear on more than one curve because of different speeds and impeller sizes available. Use the variable speed curves for gasoline or diesel engines. If an electric motor is to be used, remember the lower the RPM, the longer the service-life of the pump. Now, decided on the curve that best suits the application of desired GPM, head feet, and RPM. This curve will designate the proper pump size. Refer to the desired operating point and take an impeller size reading. 1. Select the impeller size: A. For speeds of 1750 RPM and below read to the nearest i/i inch above the operation point. B. For speeds above 1750 RPM, read to the nearest i/g inch above the operation point. 2. Calculate the required horsepower: A. Read horsepower from curve at operating point on impeller (selected as accurately as possible) then: Brake Horsepower Required=Curve HPxSp.Gr. of Fluid B. Alternate method: Read Efficiency at the operation point. Brake Horsepower = (GPM) (Hd. Ft.) (Sp. Gc.) (3960) (Efficiency) 3. Calculate your systems NPSH available in feet: NPSH available = P^ - Friction loss + Elevation - Vapor Pressure P^ = Absolute pressure above liquid in feet of fluid Absolute Pressure = Gauge Pressure + Atmospheric Pressure Elevation = Distance from Surface of liquid on suction side to center line of pump in feet (above +: Below -). Vapor Pressure = Vapor Pressure fluid at pumping temperature in feet of fluid. 4. Read NPSH required from curve. A. NPSH available must be equal to or greater than NPSH required or the pump will cavitate. B. If NPSH required is greater than NPSH available, consider: (1) Using larger suction pipe to lower losses (2) Raising the fluid level (3) Over sizing the pump (4) Lowering pump speed and increasing impeller diameter to meet the same operating point. 2 WWW.DARITECH.COM 4

START-UP AND OPERATION BEARING LUBRICATION: Standard pumps are shipped pre-lubed with grease. They should be lubricated monthly. PRIMING: Vent air from suction line and pump housing to allow them to fill completely with fluid while priming. For pumps with a flooded suction, slightly open the discharge valve and fully open the suction valve. This will allow the pump and suction line to fill completely. START-UP: The pump needs to be flooded on start-up to protect the mechanical seal. Caution to be given on high pressure systems that the pump does not draw too much power until system is flooded. GreenLine s Mechanical Seal Our GreenLine Mechanical Seal is a Tungsten Carbide Rotating Assembly manufactured in the USA. Plus a 316 stainless steel cage assembly machined from solid stock with silicone carbide stationary for greater wear life. 4 WWW.DARITECH.COM 6

PREMIUM 250 GREENLINE SLURRY PUMP The concentric housing is 35% thicker for extra strength and extended service life and reduces the radial load of the bearings. Open-vaned impeller is designed to reduce turbulence, eliminate recirculation, lower radial and thrust load, and provide a smooth flow of fluids. The larger diameter shaft gives heavy-duty performance with minimum shaft deflection. Heavy-duty outboard bearing assembly consists of a pair of angular contact bearings with high thrust load rating and zero end play. The heavy-duty inboard bearing is a double row ballbearing with high radial load rating to compensate for the larger size impeller and heavy-duty applications.

Understanding pump performance curves: The head vs flow curves on the following pages give your the performance of GreenLine 250 series pumps at various speeds and with various impeller sizes. The horsepower (hp) rating is based on pumping water with a specific gravity of 1.0. The flow is measured in US liquid gallons per minute (GPM). The total differential head is measured in feet. There are also a series of Efficiency and Net Positive Suction Head Required (NPSHr) lines showing the pump hydraulic efficiency and minimum NPSHr. The performance curves are plotted based on actual test results for each size of pumps running at various RPM and with various impeller sizes. To determine the HP required for your system you will need to determine the Specific Gravity (Sp. Gr.) of the fluid being transferred and then multiply the Sp. Gr. by the HP shown on the curve. To determine Sp. Gr.: Specific Gravity = ppg of fluid 8.34 250 Series GreenLine Pump Performance Curves 13 1-800-701-3632 11

PREMIUM 118 GREENLINE SLURRY PUMP Concentric housing design is available in right hand operation. It reduces turbulence within the pump to minimize cavitation, shaft deflection, and excessive wear. The semi open impeller is designed to handle water or heavy slurries with equal efficiency. Replaceable wear plates protects the pedestal from wear and corrosion caused by fluids being pumped, therefore, extending the life of the pump. The beefed-up frame design is stronger and more rigid in all wear areas utilizing mechanical seal system for low service. Heavy duty bearings are well protected by spring type oil seals and water slinger designed to keep fluid and dirt out of the bearing cavity. Eccentric locks are used so the shaft can be easily removed without special tools. The oil bath lubrication system is designed with a larger oil reservoir, that provides free circulation of oil and better heat dissipation for longer bearing life.

Understanding pump performance curves: The head vs flow curves on the following pages give your the performance of GreenLine 118 series pumps at various speeds and with various impeller sizes. The horsepower (hp) rating is based on pumping water with a specific gravity of 1.0. The flow is measured in US liquid gallons per minute (GPM). The total differential head is measured in feet. There are also a series of Efficiency and Net Positive Suction Head Required (NPSHr) lines showing the pump hydraulic efficiency and minimum NPSHr. The performance curves are plotted based on actual test results for each size of pumps running at various RPM and with various impeller sizes. To determine the HP required for your system you will need to determine the Specific Gravity (Sp. Gr.) of the fluid being transferred and then multiply the Sp. Gr. by the HP shown on the curve. To determine Sp. Gr.: Specific Gravity = ppg of fluid 8.34 118 Series GreenLine Pump Performance Curves 29 1-800-701-3632 27
