The HC2DHW is a dual-acting stainless unit which is capable of delivering up to 5.0 l/min flow on the high-pressure end. Like other miniBOOSTER models, the HC2DHW 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 HC2DHW is a compact unit weighing 8.0 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 trough 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 high-pressure side H is reached. If a pressure drop on the high-pressure side 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 HC2DHW
Ordering example of an HC2DHW with i = 4.0, DV incorporated, BSPP connections and H-PUR dynamic seals:
HC2DHW – 4.0 – B – 1HH for media < 5 cSt (mm2/s) tested in water
HC2DHW – 4.0 – B – 1SHH for media > 5 cSt (mm2/s) tested in hydraulic oil
High-pressure adapter is required, please specify ordering code – see high-pressure adapter table.
High-pressure adapters will be factory mounted.
