What is a Hydraulic Vane Pump Unit?

A Hydraulic Vane Pump Unit is a power system driven by an electric motor that uses a fixed-displacement vane pump to deliver a continuous and stable hydraulic oil flow. As the vanes rotate along the cam ring surface, the internal chamber alternates between suction and discharge phases—expanding during suction and contracting during discharge—to create a smooth oil flow.

This unit is composed of:

  • Vane Pump

  • Accumulator

  • Unload Valve

  • Control Valves and Gauges

Together, these components maintain optimal hydraulic pressure through load/unload cycling, ensuring stable performance during repeated load and no-load operation.

Key Features of the Nakakita Seisakusho Hydraulic Vane Pump Unit (Hydraulic Power Unit – Fixed Displacement Vane Pump Unit)

Stable Pressure Control with Fixed Displacement

The fixed-displacement vane pump provides smooth, pulsation-free operation. Its consistent displacement makes it ideal for applications requiring stable and repeatable hydraulic output.

Integrated Accumulator System

The accumulator ensures continuous pressure supply, helps absorb shock during hydraulic transitions, and supports efficient load/unload operation.

Optimized for Marine Operation Systems

The system can operate pneumatic-hydraulic control valves, remotely actuated butterfly valves, and other shipboard mechanisms requiring dependable hydraulic pressure.

Remote Operation Capability

From a control panel or machine-side interface, operators can remotely control valve actuation. Position signals can also be fed back to the control panel for precise monitoring and execution.
