MiniBOOSTER Hydraulic Intensifier HC22W-2.8-A-1S

Product Description

The HC22W – 2.8 – A – 1S is a compact miniBOOSTER stainless steel 316L steel unit weighing only 2.3 kg/5.0 lbs. It is ideal for use in a variety of applications where building and maintaining high pressure is required. The HC22W raises supplied pressure to a higher outlet pressure and automatically compensates for media consumption to maintain the high pressure. The HC22W incorporates a Pressure Reducing Valve (PRV) to control inlet pressure to the booster section, and an optional orifice to reduce inlet flow to the maximum allowed for the intensification ratio selected. The integrated Pressure Reducing Valve (PRV) protects both booster and high-pressure tool against too high pressure. It secures a stable high pressure regardless of changes in the tank line pressure.

Function description

The basic operation is illustrated in the function diagram. Media is fed through the directional valve (in the customer system) to the IN port, flowing freely through the PRV (pos. 5) and the internal check valves 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, the internal check valves 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 HC22W

Ordering examples of an HC22W:
with i = 2.8, DV incorporated with BSPP connections for media < 5 cSt (mm2/s) tested in water: HC22W – 2.8 – A – 1S

with i = 2.8, DV incorporated with BSPP connections for media > 5 cSt (mm2/s) tested in oil: HC22W – 2.8 – A – 1S

Attention note!

Valve pre-setting is required, please specify when ordering the intensifier.

Dynamic – low hysteresis: Ordering example of an HC22W with i = 2.8 RV incorporated and BSPP connections: HC22W – 2.8 – A – 1S .
Fail safe – high hysteresis: The RV valve opening ratio is to be determined on individual basis. Contact our technical support.
