The HC2D is a high-flow dual-acting unit, which is capable of delivering up to 11.0 l/min flow on the high-pressure end.
Like other miniBOOSTER models, the HC2D raises supplied pressure to a higher outlet 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. Relative to its flow capability, the HC2D is a compact unit weighing 3.4 kg.

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 2x KV1, 2x 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 units OP1 and OP2 by turns. 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 OP1 and OP2 units will automatically operate to maintain the end pressure. It is possible to change the high-pressure connection H to the opposite end of the booster.

Ordering an HC2D
Ordering example of an HC2D with i = 4.0, DV incorporated and BSPP connections: HC2D – 4.0 – B – 1
The G-model is available in 2 variants, when ordering please specify accordingly:
- Dynamic – low hysteresis: Ordering example of an HC2D with i = 4.0 RV incorporated and BSPP connections: HC2D – 4.0 – 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 HC2D with i = 4.0 RV with opening ratio x.x incorporated and BSPP connections: HC2D – 4.0 – G – x.x – 1
