Mat. Certificate 3.1 on request

 

Description

The HC2D-D is a high flow dual acting unit which is capable of up to 11.0 l/min flow on the high pressure end. Like other miniBOOSTER models, the HC2D-D 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-D is a compact unit weighing 3.5 kg. The hole pattern is a miniBOOSTER design.

Functions

The basic operation is illustrated in the function diagram. Oil is fed through the directional valve CV to the IN port, flowing freely trough 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 there is 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.
