HC4W miniBOOSTER

HC4W versions: 9 different intensification factors

PIN: Inlet pressure 20-207 bar

PH: 800 bar maximum (outlet pressure)

PRETURN: As low as possible (return pressure to tank)

POUTLET: PH = (PIN – PReturn) i ( intensification)

Mounting: Inline tube

Accessories: Pilot-operated dump valve available

A model = no dump valve
B model = with dump valve
G model = direct proportionally controlled

 

 

Description

The HC4W is ideal for use in applications where a higher volume of high-pressure fluid is required. The HC4W is a compact stainless steel unit weighing only 4.5 kg, but it delivers up to 7.0 liters/min. outlet flow.

Like the HC2W, it raises supplied pressure and automatically compensates for consumption of media to maintain the high pressure. Adjustment of the outlet pressure is carried out by varying the supplied pressure relative to its flow capability.

Functions

The basic operation is illustrated in the function diagram. Water 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 HC4W

Ordering example of an HC4W with i = 4.3, DV incorporated and BSPP connections:
HC4W - 4.3 - B - 1 for media < 5 cSt (mm2/s) tested in water
HC4W - 4.3 - B - 1S for media > 5 cSt (mm2/s) tested in hydraulic oil
