Product Description

The HC7 – 9.0 – G – 9 is a lightweight, compact high-pressure unit, weighing just 1.3 kg/ 2.8 lbs, capable of delivering pressures up to 2,000 bar. Designed for easy mounting on manifolds, cylinders, or other devices, it automatically adjusts outlet pressure to maintain high pressure levels by compensating for oil consumption. Outlet pressure can be adjusted by varying the supplied pressure.

Additional information

Function description

The basic operation is illustrated in the function diagram. Oil is fed through the directional valve CV to the IN port, flowing freely through the check valves KV1, KV2 and DV to the high-pressure side H. In this condition maximum flow through the booster is achieved, giving a fast-forward function. When pump pressure is reached on the high-pressure side H, valves KV1, KV2 and DV will close. The end pressure will be achieved by the oscillating pump unit OP. The unit will automatically stall when end pressure on the high-pressure side H is reached. If a pressure drop on the high-pressure side exists due to consumption or leakage, the OP valve will automatically operate to maintain the end pressure.

Ordering an HC7-9

Ordering example of an HC7-9 with i = 4.0 DV incorporated: HC7 – 9.0 – G – 9

Attention note!

The G-model is available in 2 variants, when ordering please specify accordingly:

  • Dynamic – low hysteresis: Ordering example of an HC7-9 with i = 9.0 RV incorporated: HC7 – 9.0 – G – 9.
  • Fail safe – high hysteresis: The RV valve opening ratio is to be determined on individual basis. Contact our technical support.

Ordering example of an HC7-9 with i = 9.0 RV with opening ratio x.x incorporated: HC7 – 9.0 – G – x.x – 9
