HC22 versions: 15 different intensification factors
PIN: 20 – 207 bar
PH: 800 bar maximum
PRETURN: As low as possible (return pressure to tank)
POUTLET: PH = (PIN – PRETURN) x i (intensification)
Mounting: Inline tube
Weight: 2.3 kg.
The HC22 is a compact unit weighing only 2.3 kg. It is ideal for use in a variety of applications where building and maintaining high pressure is required.
The HC22 raises supplied pressure to a higher outlet pressure and automatically compensates for oil consumption to maintain the high pressure.
The HC22 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.
|Max. intensified outlet flow|
|Max. inlet flow|
The basic operation is illustrated in the function diagram. Oil 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.
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 HC22
Ordering example of an HC22 with i = 4.0, DV incorporated and BSPP connections: HC22 – 4.0 – B – 1
The G-model is available in 2 variants, when ordering please specify accordingly:
- Dynamic – low hysteresis: Ordering example of an HC22 with i = 4.0 RV incorporated and BSPP connections: HC22 – 4.0 – 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 HC22 with i = 4.0 RV with opening ratio x.x incorporated and BSPP connections: HC22 – 4.0 – G – x.x – 1
