MiniBOOSTER Hydraulic Intensifier HC8-10.3-B

Product Description

The HC8 – 10.3 – B – is a compact, self-contained device designed for applications requiring intensified pressure up to 2,000 bar. Similar to the HC2, it autonomously boosts inlet pressure up to 20 times without external power. Additionally, it automatically compensates for oil consumption on the high-pressure side, maintaining consistent high pressure. Weighing just 4.5 kg, the HC8 operates at inlet pressures ranging from 20 to 207 bar, with higher pressures available upon request.

Functions Desctiption

The system operates as follows: Oil is directed through the directional valve (CV) to the IN port, where it flows freely through check valves (KV1, KV2, and DV) to the high-pressure side (H), maximizing booster flow for fast-forward functionality. Once pump pressure is attained on the high-pressure side, valves KV1, KV2, and DV close. The oscillating pump unit (OP) then achieves the desired end pressure, automatically stalling upon reaching the target pressure. If pressure drops occur due to consumption or leakage on the high-pressure side, the OP valve automatically adjusts to maintain the end pressure.

Ordering an HC8

Ordering example of an HC8 with i = 13.0, H1 M22 x 1.5 and H2 9/16-18 UNF, DV incorporated and BSPP connections: HC8 – 13.0 – B – 12U
Ordering example of an HC8 with i = 13.0, DV incorporated and BSPP connections, mounted with high-pressure plate with HP-connection 1/4″ BSPP, PG-connection 9/16-18 UNF:
HC8 – 13.0 – B – 1 with 8-285

Attention note!

High-pressure plate is required, please specify ordering code – see high-pressure plate table.
High-pressure plate will be factory mounted.

The G-model is available in 2 variants, when ordering please specify accordingly:

Dynamic – low hysteresis: Ordering example of an HC8 with i = 13.0 RV incorporated and BSPP connections: HC8 – 13.0 – G – 1
Fail safe – high hysteresis: The RV valve opening ratio is to be determined on individual basis. Contact our technical support. Ordering example of an HC8 with i = 13.0 RV with opening ratio x.x incorporated and BSPP connections: HC8 – 13.0 – G – x.x – 1.
