Description of the HC8W miniBOOSTER hydraulic intensifier
The HC8W is a high pressure stainless steel unit delivering pressure up to 2.000 bar. Operating like the HC2W, the HC8W is a unique, self contained device which boosts inlet pressure by up to a 20:1 ratio without the use of external power.
In addition, the HC8W maintains high pressure by automatically compensating for consumption of media on the high pressure side. High pressure is directly proportional to inlet pressure. The HC8W is compact in size. The HC8W works at inlet pressure from 20 to 200 bar. On standard versions maximum outlet pressure is 2,000 bar. Higher pressure is available on special request.

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.
