HC8H versions: 5 different intensification factors
PIN: 20-207 bar
PH: 3,000 bar maximum
PRETURN: As low as possible (return pressure to tank)
POUTLET: PH = (PIN – PRETURN) x i (intensification)
Mounting: Inline tube
Weight: 4.7 kg.
The HC8H is developed for applications where intensified pressure up to 3,000 bar are required. Operating like the HC2, the HC8H is a unique, self-contained device which boosts inlet pressure up to a 25:1 factor without the use of an external power source.
In addition, the HC8H maintains high pressure by automatically compensating for consumption of oil on the high-pressure side. High pressure is directly proportional to inlet pressure. The HC8H is a compact unit weighing 4.7 kg. The HC8H works at inlet pressure from 20 to 207 bar.

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 HC8H
Ordering example of an HC8H with i = 13.0, DV incorporated and BSPP connections, mounted with high-pressure plate with HP-connection 1/4″ BSPP, PG-connection 9/16-18 UNF:
HC8H – 13.0 – B – 1 with 8-285
High-pressure plate is required, please specify ordering code – see high-pressure plate table.
High-pressure plate will be factory mounted.
The G-model is available in 2 variants, when ordering please specify accordingly:
- Dynamic – low hysteresis: Ordering example of an HC8H with i = 13.0 RV incorporated and BSPP connections: HC8H – 13.0 – 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 HC8H with i = 13.0 RV with opening ratio x.x incorporated and BSPP connections: HC8H – 13.0 – G – x.x – 1
