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

Description & Features

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).
Fluid Viscosity	80-180 SSU is optimum. 60 SSU is low intermittent limit. 10,000 SSU is high intermittent limit (cold start-up).
Peak Pressure	6000 PSI (Peak Pressure should not exceed 1% of operating time).
Recommended Filtration	ISO 4406 Cleanliness Level 18/13 or cleaner.
System Temperature	180°F Normal Continuous Limit, 220°F Maximum Intermittent Limit.

Question by: Tammy B on Jul 1, 2025, 7:24 PM

What kind of upkeep do these motors need to keep them running smooth?

Answer by: Customer Support on Jul 3, 2025, 6:18 AM

Keeping your hydraulic fluid clean is key; shoot for an ISO 4406 Cleanliness Level 18/13 or better to avoid problems down the road. Also, keep an eye on the temperature, try not to let it run over 180°F for too long or exceed 220°F even for short bursts.
