Medium-Pressure Hydraulic Power Units — 0 to 50 MPa (0 to 500 bar)

Medium-Pressure Hydraulic Power Units

These units are designed to supply working fluid to the hydraulic systems of industrial and test presses, as well as to power:

  • High-load hydraulic cylinders;
  • Ship winch drives;
  • Pipeline testing and pressure-testing systems;
  • The drives of various high-power hydraulically actuated equipment (such as knuckle boom cranes).

These units also serve as a basis for creating complete hydraulic drives, which power the hydraulic systems and enable remote control of the hydraulically actuated working components of the equipment.

Hydraulic Power Units 0…50 MPa (0…500 bar)

Hydraulic power units may include the following components:

  • Additional manifolds for solenoid valves and control equipment.
  • Pressure line filter.
  • Return line filter.
  • A heat exchanger with air or water cooling.
  • Temperature sensor.
  • Oil level sensor and other sensors.

Parameters:

  • Rated tank capacity: 5 — 1000 L
  • Rated flow: 0.1 — 500 L/min
  • Rated operating pressure: 16 — 50 MPa

Hydraulic power units operating in the 16–50 MPa range perform the drive functions for hydraulic cylinders. They are used to:

  1. Supply oil to the hydraulic systems of test and pressure-testing equipment;
  2. Drive the actuators of high-load hydraulic presses;
  3. Activate the power hydraulics of ship machinery, cranes, lifting equipment, and loaders.

The pressure at which the working fluid is supplied is regulated by a relief valve.

Izhora Hydrosystems LLC offers the following solutions:

  1. Hydraulic power units for presses, with various tank capacities and operating oil flow rates from 12 to 165 L/min.
  2. Hydraulic power units for cranes and marine systems, with various tank capacities and operating oil flow rates of up to 500 L/min.
