PIN: 20 – 207 bar
PH: 2,000 bar maximum
PRETURN: As low as possible (return pressure to tank)
POUTLET: PH = (PIN – PRETURN) x intensification factor
Mounting: Flange, manifold system miniBOOSTER pattern
Weight: 1.7 kg.
Description
The HC7-F is a very compact high-pressure unit capable of delivering pressure up to 2,000 bar weighing only 1.7 kg. The HC7-F is a variant of the HC7 for flange mounting on the low pressure side. The entire pattern is a miniBOOSTER design. It is ideal for use in portable applications like on power packs.
The HC7-F 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.

Ordering an HC7-F
Ordering example of an HC7-F with i = 13.0, H1 M22 x 1.5 and H2 9/16-18 UNF, DV incorporated and BSPP connections: HC7 – 13.0 – B – F2
Attention notes!
High-pressure adapter is required, please specify ordering code – see high-pressure adapter table.
High-pressure adapters will be factory mounted.
The G-model is available in 2 variants, when ordering please specify accordingly:
- Dynamic – low hysteresis: Ordering example of an HC7-F with i = 13.0 RV incorporated, H1 M22 x 1.5 and H2 9/16-18 UNF and BSPP connections: HC7 – 13.0 – G – F2
- Fail safe – high hysteresis: The RV valve opening ratio is to be determined on individual basis. Contact our technical support. Ordering example of an HC7-F with i = 13.0 RV with opening ratio x.x incorporated, H1 M22 x 1.5 and H2 9/16-18 UNF and BSPP connections: HC7 – 13.0 – G – x.x – F2
