Proper Pump Selecton

Inside Front Cover Proper Pump Selecton

Careful selection and installation of the correct Dragon Centrifugal 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. Centrifugal 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 other reason the discharge pressure is much lower than expected, the pump will handle considerably more fluid and require more horsepower thanoriginally 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 dynamic head 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. Mark 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, decide 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 operating point. B. For speeds above 1750 RPM, read to the nearest i/g inch above the operating 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 operating 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 Surf ace 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) Oversizing the pump (4) Lowering pump speed and increasing impeller diameter to meet the same operating point. Start-Up and Operation BEARING LUBRICATION: All Dragon pump bearings are prelubricated when assembled. We use Mystic JT-6 HT #2 when assembling and recommend that the same or a compatible NLGI #2 high temp be used. It is recommended that 5-10 shots of grease are injected into both the inboard and outboard bearing lubrication fittings at least monthly. Pumps assembled with the optional oil lubrication should be checked regularly with the dipstick and refilled with a good grade of non-detergent SAE 30 motor oil.

STUFFING BOX PACKING: Most Dragon 250 pumps come standard with a mechanical seal and a back-up graphite packing in case of seal failure. The back-up packing should be left loose until needed, after which the packing bland bolts should be tightened slowly until the stuffing box drips 6-10 drips per minute. The packing should be greased daily.

PRIMING: Vent air from suction line and pump housing to allow them PUMP PERFORMANCE COMPUTATIONS: to fill completely with fluid while priming. For pumps with a To compute pump performance of variations from flooded suction, slightly open the discharge valve and fully pump curves use the following formulas: (Approximate) open the suction valve. This will allow the pump and suction line to fill completely.

Premium 118 Centrifugal Pump Concentric housing design is available in right hand or left 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 pump, therefore, extending the life of the pump. The beefed-up frame design is stronger and more rigid in all wear areas.It gives a larger work area to facilitate packing the pump, which cuts repacking time. 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.

Mud Guns- The Dragon Mud Gun is designed for submerged service in pits and is available in a 3” size low-pressure gun. This unit is intended for high volume service, such as mud mixing systems that employ centrifugal pumps. All Dragon Mud Guns are available with 360°rotation handles, which aid the swivel joints. For reducing the amount of solid buildup in tank corners, Dragon Mud Guns are highly effective. They also produce flow currents, which boost fluid movements and aid in the suspension or mixing of particles. In addition, Mud Guns can create an alternate product flow when used in conjunction with agitators. Available in one and two gun configurations. Agitators
