MiniBOOSTER Hydraulic Intensifier HC7-10.3-G

Product Description

The HC7 – 10.3 – G is a remarkably compact high-pressure unit, weighing just 1.5 kg yet capable of delivering pressures of up to 2,000 bar. Designed for portable applications such as power packs, it efficiently elevates supplied pressure to a higher outlet pressure while automatically adjusting for oil consumption to sustain the desired high pressure. Outlet pressure adjustment is achieved by modifying the supplied pressure. With adaptable high-pressure adapters, various thread types can be accommodated, starting from the M22x1.5 thread in the HP port. Higher pressure options are also available upon request.

Functions Desctiption

This system utilizes a directional valve (CV) to regulate the flow of oil, allowing it to pass through check valves (KV1, KV2, and DV) to reach the high-pressure side (H). Initially, maximum flow through the booster is attained for rapid forward motion. Once pump pressure is attained on the high-pressure side, the valves (KV1, KV2, and DV) close. The oscillating pump unit (OP) then maintains the end pressure automatically, stalling when the desired pressure is reached. Should there be a pressure drop due to consumption or leakage, the OP valve adjusts accordingly to uphold the end pressure.

Ordering an HC7

Ordering example of an HC7 with i = 13.0, H1 M22 x 1.5 and H2 9/16-18 UNF, DV incorporated and BSPP connections: HC7 – 13.0 – B – 12

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 HC7 with i = 13.0 RV incorporated, H1 M22 x 1.5 and H2 9/16-18 UNF and BSPP connections: HC7 – 13.0 – G – 12.
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 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 – 12 .
