Highland Variable Piston Pumps for Forage Harvesters

Forage harvesters operate under demanding field conditions and require reliable hydraulic power for smooth machine movement and stable operation. Highland HPV series variable displacement piston pumps are designed for closed-circuit hydrostatic transmission systems in agricultural machinery.

With variable displacement control, the HPV series adjusts hydraulic output according to operating requirements. This supports smooth speed regulation and responsive driving performance during harvesting operations.

Key Features

• Variable Displacement Design: Adjusts pump displacement to meet different machine speed and load requirements.

• Closed-Circuit Operation: Designed for hydrostatic transmission systems used in mobile agricultural machinery.

• High-Pressure Capability: HPV series specifications include rated working pressure up to 35 MPa and maximum instantaneous working pressure up to 42 MPa, depending on model and operating conditions.

• Multiple Control Options: Available with manual servo, hydraulic servo, and electric proportional servo configurations.

Applications

Highland HPV variable piston pumps can be applied to compatible hydraulic drive systems in:

• Forage harvesters

• Silage harvesters

• Combine harvesters

• Agricultural machinery

• Self-propelled harvesting equipment
