HC2D2 versions: 8 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)
The intensification ratio is related to the inlet pressure on media 2, the values in the table are measured at 1 bar on media 2.
Drain connections: Max. 5 bar
Mounting: Inline tube
Weight: 4.2 kg.
A model = no dump valve
Material certificate 3.1 on request
The HC2D2 is a dual media unit which is capable of delivering up to 4.2 l/min flow on the high-pressure end. Like other miniBOOSTER models, the HC2D2 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 HC2D2 is a compact unit weighing 4.2 kg.

The basic operation is illustrated in the function diagram. Media 1 is fed through the IN port flowing freely through the bistable valve BV1 driving the LP pistons. From the suction inlet IN Media 2 is drawn through the check valves 2 x KV1, and pumped through the 2 x KV2 to the high-pressure side H. In this condition, maximum flow through the booster is achieved giving a fast-forward function.
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 HP1 and HP2 units will automatically operate to maintain the end pressure.
