MiniBOOSTER Hydraulic Intensifier HC7-10.3-A-W

Product successfully added to the Quote List

Product Description

The HC7 – 10.3 – A – W a compact stainless steel 316L miniBOOSTER, delivers pressures up to 2,000 bar, weighing just 1.5 kg. Designed for thin (low viscosity) media, it’s perfect for portable applications like power packs. It elevates supplied pressure to higher outlet levels and automatically compensates for media consumption to maintain high pressure. Outlet pressure adjustment is achieved by varying the supplied pressure. Various high-pressure adapters allow for different thread options from the M22x1.5 thread in the HP port.

Functions Description

The system operates through a directional valve CV, guiding media to the IN port, then through check valves KV1, KV2, and DV to the high-pressure side H, ensuring maximum booster flow for rapid function. Once pump pressure is reached, valves KV1, KV2, and DV close, and the oscillating pump unit OP regulates end pressure. OP stops automatically at the desired pressure. It adjusts to maintain pressure if there’s a drop due to consumption or leakage.

Ordering an HC7W

Ordering example of an HC7W with i = 13.0, H1 M22 x 1.5 and H2 19/16-18 UNF.DV incorporated and BSPP connections:

HC7W – 13.0 – B – 12 for media < 5 cSt (mm2/s) tested in water HC7W – 13.0 – B – 12S for media > 5 cSt (mm2/s) tested in hydraulic oil

Attention note!

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 with i = 13.0 RV incorporated, H1 M22 x 1.5 and H2 9/16-18 UNF and BSPP connections: HC7W – 13.0 – G – 12S
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, H1 M22 x 1.5 and H2 9/16-18 UNF and BSPP connections: HC7W – 13.0 – G – x.x – 12S
