The HC7W miniBOOSTER

HC7W versions: 5 different intensification factors PIN: 20 – 200 bar (inlet pressure) PH: 2000 bar maximum (outlet pressure) PRETURN: As low as possible (Return pressure to tank) Intensification ratios: PH = (PIN – PReturn) i (Intensification) Mounting: Inline tube Accessories: Pilot operated dump valve incorporated A model = no dump valve B model = with dump valve G model = direct proportionally controlled

  Description of the HC7W miniBOOSTER hydraulic intensifier

The HC7W is a very compact high pressure unit capable of delivering pressure up to 2000 bar with an weight of only 1.5 kg. It is ideal for use with very thin (low viscosity) medias. It is ideal for use in portable applications like on power packs.

The HC7W 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. With the choice of different high pressure adapters a variety of threads can be obtained from the M22x1.5 thread in the HP port.

  Functions

The basic operation is illustrated in the function diagram. Media 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 high pressure side H is reached. If there is a pressure drop on the high pressure side due to consumption or leakage, the OP valve will automatically operate to maintain the end pressure.
