HC7W-FF versions: 10 different intensification factors
PIN: 20-207 bar
PH: 2,000 bar maximum for media > 5 cSt (mm2/s)
PH: 1,035 bar maximum for media < 5 cSt (mm2/s)
PRETURN: As low as possible (return pressure to tank)
POUTLET: PH = (PIN – PRETURN) x i (intensification)
Mounting: Flange, manifold system miniBOOSTER pattern
Weight: 2.0 kg.
The HC7W-FF is a very compact high-pressure miniBOOSTER stainless steel 316L unit capable of delivering pressure up to 2,000 bar weighing only 2.0 kg. The HC7W-FF is a variant of the HC7W for flange mounting on both high- and low pressure side. The entire pattern is a miniBOOSTER design. It is ideal for use with very thin (low viscosity) medias and for use in various applications like on power packs.
The HC7W-FF 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.

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 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 HC7W
Ordering example of an HC7W-FF with i = 13.0, H, IN and R flanged and H2: 9/16-18 UNF and DV incorporated:
HC7W – 13.0 – B – FF2 for media < 5 cSt (mm2/s) tested in water
HC7W – 13.0 – B – FF2S for media > 5 cSt (mm2/s) tested in hydraulic oil
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 HC7W-FF with i = 13.0 RV incorporated, H, IN and R flanged and H2: 9/16-18 UNF : HC7W – 13.0 – G – FF2S
- Fail safe – high hysteresis: The RV valve opening ratio is to be determined on individual basis. Contact our technical support. Ordering example of an HC7W with i = 13.0 RV with opening ratio x.x incorporated, H, IN and R flanged and H2: 9/16-18 UNF: HC7W – 13.0 – G – x.x – FF2S
