HC7 miniBOOSTER

Description

The HC7 is a very compact high- pressure unit capable of delivering pressure up to 2,000 bar weighing only 1.5 kg. It is ideal for use in portable

applications like on power packs.

The HC7 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. Higher pressure is available on request.

Functions

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 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 the high- pressure side H is reached. If a pressure drop on the

high- pressure side exists due to consumption or leakage, the OP valve will automatically operate to maintain the end pressure.

HC7 versions: 5 different intensification factors
