HC8: 5 different intensification factors
Visit our website for more details.
A Model = Without Dump Valves
B Model = With Dump Valves
G Model = Direct Proportionally Controlled
The HC8 is developed for applications where intensified pressure up to 2,000 bar are required. Operating like the HC2, the HC8 is a unique, self-contained device which, boosts inlet pressure by up to a 20:1 ratio without the use of an external power source.
In addition, the HC8 maintains high pressure by automatically compensating for consumption of oil on the high-pressure side. High pressure is directly proportional to inlet pressure. The HC8 is a compact unit weighing 4.5 kg. The HC8 works at inlet pressure from 20 to 200 bar. Higher pressure is available on special request.
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.
