Heavy Duty Hydrostatic Motors, Up To 7.62 cu in/rev, Up To 6000 PSI, Up To 4500 RPM

CAUTION

 Before the motor is started, fill the case through the uppermost drain port with hydraulic fluid of the type to be used. (The typical installation has the excess charge pump flow from the motor's charge pressure relief valve flushing the case on the pump. The motor's upper case drain line connects to the lower case port on the pump. The upper case port on the pump returns back to tank, often through a heat exchanger). The case of the pump and motor must remain full at all times.

Features

 6000 PSI Pressure Rating. 10,000 Hour B10 Bearing Design Life. Advanced cylinder barrel design permits high speed and pressure. Pistons have long engagement with cylinder bore resulting in low leakage. High strength cast iron housings provide greater noise damping and wall strength. Bi-metal bearing plate has steel for high speed and pressure and bronze for greater bearing properties. A wide variety of configurations and options are available (Contact us for additional information).
