MiniBOOSTER Hydraulic Intensifier HC7-25.0-G-H

Product successfully added to the Quote List

Product Description

The HC7 – 25.0 – G – H is a very compact high-pressure unit capable of delivering pressure up to 2,600 bar weighing only 1.5 kg. It is ideal for use in portable applications like on power packs. The HC7H 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. With the choice of different high- pressure adapters, a variety of threads can be obtained from the M22x1.5 thread in the HP port.

Flow Rate

i (Intensification factor)	Max. intensified outlet flow (l/min)	Max. inlet flow (l/min)
10.0	0.8	12.0
13.0	0.6	12.0
16.0	0.5	12.0
20.0	0.3	12.0
25.0	0.2	12.0

Functions Description

The basic operation is illustrated in the function diagram. Oil 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 HC7

Ordering example of an HC7H with i = 13.0, H1 M22 x 1.5 and H2 9/16-18 UNF, DV incorporated and BSPP connections: HC7H – 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 HC7H with i = 13.0 RV incorporated, H1 M22 x 1.5 and H2 9/16-18 UNF and BSPP connections: HC7H – 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 HC7H 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: HC7H – 13.0 – G – x.x – 12
