HC9 version: 8 intensification factor
PIN: 20 – 207 bar
PH: 5,000 bar maximum
PRETURN: As low as possible (return pressure to tank)
POUTLET: PH = (PIN – PRETURN) I (intensification)
Mounting: Inline tube
Weight: 9.9 kg.
The HC9 is an ultra high-pressure unit which is capable of delivering up to 5,000 bar and 0.4 l/min flow on the high-pressure end. Like other miniBOOSTER models, the HC9 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 HC9 is a compact unit weighing only 9.9 kg.

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 and KV2 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 and KV2 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.
