Der miniBOOSTER HC9D2

HC9D2 versions: 5 different intensification factors

PIN: 20 – 200 bar (inlet pressure)

PH: 1380 bar maximum (outlet pressure)

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

POUTLET: PH = (PIN – PReturn) X i (Intensification)
The intensification ratio is related to the inlet pressure at media 2,
the values in the table are measured at 1 bar on media 2

Drain connections: Max. 10 bar

Mounting: Inline tube

A model = no dump valve

Material certificate on request

 

 

Description

The HC9D2 is a dual media unit which is capable of up to 5.6 l/min flow on the high pressure end. Like other miniBOOSTER models, the HC9D2 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. Relative to its flow capability, the HC9D2 is a compact unit weighing 25 kg.

Functions

The basic operation is illustrated in the function diagram. Media 1 is fed through the IN port flowing freely through the bistable valve BV1 driving the LP pistons. From the suction inlet IN Media 2 is drawn through the check valves 2 x KV1, and pumped through the 2 x KV2 to the high-pressure side H. In this condition maximum flow trough the booster is achieved giving a fast forward function.

The unit will automatically stall when end pressure on high-pressure side H is reached. If there is a pressure drop on the high pressure side due to consumption or leakage, the HP1 and HP2 units will automatically operate to maintain the end pressure.
