MiniBOOSTER Hydraulic Intensifier HC7-7.6-G-F

Product successfully added to the Quote List

Product Description

The HC7 – 7.6 – G – F is an ultra-compact high-pressure unit, weighing just 1.7 kg, designed for flange mounting on the low-pressure side. With a maximum pressure capability of 2,000 bar, it is a miniBOOSTER design, perfect for portable applications like power packs. Specifically tailored for use in confined spaces, this variant of the HC7 automatically adjusts and compensates for oil consumption to maintain high pressure. Outlet pressure adjustment is achieved by varying the supplied pressure. Featuring a range of high-pressure adapters, it offers versatility with different threads, starting from the M22x1.5 thread in the HP port, and can provide higher pressure upon request. Ideal for enhancing pressure in various hydraulic systems.

Functions Desctiption

The system operates as follows: Oil is directed through the directional valve CV to the IN port, passing through check valves KV1, KV2, and DV to the high-pressure side H, allowing for maximum flow and a fast-forward function. Once the pump pressure is attained on the high-pressure side H, valves KV1, KV2, and DV close. The oscillating pump unit OP then maintains the end pressure automatically, stalling when the desired pressure is reached. In the presence of a pressure drop due to consumption or leakage on the high-pressure side, the OP valve ensures automatic operation to sustain the end pressure.

Ordering an HC7

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 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-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.
