Piston Pump, 4000 PSI, 0.88 cubic inch/rev

Variable volume pressure compensated piston pumps match flow to system demand. Your system will generate less heat, and may not need a heat exchanger. Your system can be kept simpler too, with fewer valves and regulators, while still maintaining constant pressure. For long term reliability, and optimum performance, PowrFlowT HPV Axial Piston Pumps are your best value. Heavy Duty Construction Designed for rugged use in industrial and mobile applications. Beefed up case also contributes to reduced sound levels for quiet operation.

• PowrFlow Piston Pumps Standard SAE 2-Bolt Flange Mount Available in right or left-hand rotation.


• Readily interchangeable with other piston pumps.


• Nine Piston Rotating Group Provides smooth power and quiet operation.


• Individually replaceable pistons.


• Replaceable Port Plate Simplifies servicing.


• Ports are designed to reduce noise.

Four Compensator Options

Standard Compensator - designed for quick response. On stroke response less than 120 ms., Off stroke response 50 ms.

Remote Compensator - provides the same pressure compensated performance with the added flexibility and convenience of remote pressure adjustment or multiple pressure levels.

Load Sensing Compensator - allows the pump to maintain constant flow to the system regardless of fluctuating loads to maintain maximum system efficiency and minimum heat loss.

Horsepower Limit Compensator - Matches pump output to available input horsepower by varying system pressure as system flow demand varies.
