Closed Loop Hydrostatic Pump for Agricultural Machinery

Highland variable displacement axial piston pumps are designed for closed-loop hydrostatic drive systems used in agricultural machinery. They provide adjustable hydraulic flow for machine travel and drive functions, helping equipment maintain smooth speed control under changing field conditions.

In a closed-loop hydrostatic transmission, the hydraulic pump supplies pressurized oil to a hydraulic motor, and the oil returns from the motor directly to the pump. By adjusting pump displacement, the system can regulate motor speed and change the direction of travel.

Typical Agricultural Applications

Highland closed-loop variable piston pumps can be used in compatible hydrostatic drive systems for:

• Forage and silage harvesters

• Combine harvesters

• Self-propelled agricultural machinery

• Cotton pickers

• Agricultural walking machinery

• Other specialized farming equipment
