Highland Variable Piston Pump for Hydrostatic Drive

Highland variable displacement axial piston pumps are designed for closed-loop hydrostatic transmission systems in mobile machinery. 

In a hydrostatic drive system, Highland variable piston pump supplies hydraulic oil to a compatible hydraulic motor through a closed circuit. By adjusting the pump's swashplate angle, the system can regulate oil flow and control the motor's speed and direction.

Key Features

1. Variable Displacement Design

Adjustable displacement allows hydraulic output flow to change according to machine speed and operating requirements.

2. Closed-Loop Hydrostatic Operation

Designed to work with compatible hydraulic motors in closed-circuit transmission systems for mobile machinery.

3. Multiple Servo Control Options

Available control configurations include:

• Manual servo control

• Hydraulic servo control

• Electric proportional servo control

Typical Applications

Highland PV variable piston pumps can be used in compatible hydrostatic drive systems for:

• Forage harvesters and silage harvesters

• Combine harvesters

• Road rollers and compactors

• Asphalt pavers

• Concrete mixer trucks

• Underground mining loaders (LHD)

• Other self-propelled agricultural and construction machinery
