Product Information :
Parts Page (click here)The Price Pump HP75AB-450-21511 is a Close Coupled Centrifugal Pump End, type HP series, with a Bronze volute, a 4.50 inch Bronze impeller, a Bronze bracket, Type 21 EPR/Carbon/Ceramic Mechanical Seal, 3/4 Inch FNPT Suction x 3/4 Inch FNPT Discharge, and fits a NEMA 56J footless motor. This pump end is a compact close coupled centrifugal pump end. It has a Bronze bracket and a Viton volute o-ring. The Bronze impeller threads onto the motor shaft, so the pump end mounts straight to a NEMA 56J footless motor with no coupling and no alignment to hold. It handles liquid temperatures to 300 degrees F and heads to 180 feet, with a maximum solid size of 0.030 inch and a Pump Energy Index of .746 to .892. This pump end is fitted with a Type 21 EPR/Carbon/Ceramic Mechanical Seal and takes a 3/4 Inch FNPT Suction and a 3/4 Inch FNPT Discharge, and it must be run above its minimum flow of 0.5 GPM. It is also available with a different impeller diameter: HP75AB-600-21511 at 6.00 inch, HP75AB-550-21511 at 5.50 inch, HP75AB-500-21511 at 5.00 inch and HP75AB-400-21511 at 4.00 inch. The impeller can also be trimmed to 5.75, 5.25, 4.75 and 4.25 inch, cut to order from the full size impeller, as HP75AB-575-21511, HP75AB-525-21511, HP75AB-475-21511 and HP75AB-425-21511. The curve does not draw these diameters; a trimmed pump takes the motor of the next larger diameter the curve does draw.

Applications
The Price Pump HP75AB-450-21511 is a Type HP Close Coupled Centrifugal Pump, with a Bronze volute, a Bronze impeller and a Viton o-ring.
It handles liquid temperatures up to 300 degrees F and develops up to 180 feet of head. Maximum flow is 68 GPM and minimum flow is 0.5 GPM; it must be operated above the minimum flow to avoid damage. Temperature limits are based on standard seal and gasket materials, and will vary according to the liquid being pumped.
The maximum solid size is 0.030 inch, and the suction must be flooded. This pump end is fitted with the EPR/Carbon/Ceramic mechanical seal.
Typical Applications for the Price Pump HP75AB-450-21511 are chillers and liquid cooling, chemical processing, booster pumps, water purification, circulation and filtration and air conditioning and heat recovery.
The mechanical seal is chosen for the liquid being pumped. The three digits after the seal type in the model number are its elastomer, its washer and its seat. The Price Pump manual lists chemical attack of the seal parts as a cause of a leaking seal, and temperature limits vary with the liquid and the sealing materials used. Check the materials against your liquid before ordering.
