HC4 versions: 10 different intensification factors
PIN: 20 – 207 bar
PH: 800 bar maximum
PRETURN: As low as possible (return pressure to tank)
POUTLET: PH = (PIN – PRETURN) i (intensification)
Mounting: Inline tube
Weight: 3.7 kg.
The HC4 is ideal for use in applications where a higher volume of high-pressure fluid is required. The HC4 is a compact unit weighing only 3.7 kg, but it delivers up to 16.3 l/min outlet flow.
Like the HC2, it raises supplied pressure and automatically compensates for consumption of oil to maintain the high pressure. Adjustment of the outlet pressure is carried out by varying the supplied pressure.

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 HC4
Ordering example of an HC4 with i = 4.3, DV incorporated and BSPP connections: HC4 – 4.3 – B – 1
The G-model is available in 2 variants, when ordering please specify accordingly:
- Dynamic – low hysteresis: Ordering example of an HC4 with i = 4.3 RV incorporated and BSPP connections: HC4 – 4.3 – G – 1
- Fail safe – high hysteresis: The RV valve opening ratio is to be determined on individual basis. Contact our technical support. Ordering example of an HC4 with i = 4.3 RV with opening ratio x.x incorporated and BSPP connections: HC4 – 4.3 – G – x.x – 1
