Description:
HC2D2W is a dual media unit which is capable of delivering up to 4.2 l/min flow on the high-pressure end. Like other miniBOOSTER models, the HC2D2W 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 HC2D2W is a compact unit weighing 8.0 kg.
General 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 through 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 a pressure drop on the high-pressure side exists due to consumption or leakage, the HP1 and HP2 units will automatically operate to maintain the end pressure.
Domestic and export sales enquiries are welcome from end users, original equipment machinery manufacturers and trade suppliers from all industrial sectors.

Without Dump Valve High pressure is relieved externally. This is achieved in most cases by the use of a pilot operated check valve. |
As shown in the chart Minibooster has a dual flow/pressure feature. Initially when fluid is supplied to the booster it flows straight through to the high pressure side. At this point all the supplied flow (up to the max. allowed inlet flow) goes to the actuator allowing it to operate fast in the desired direction. As soon as inlet pressure is reached in the actuator, the flow will then be supplied via the high pressure piston until intensified pressure is reached.
Temperature range oil: -40 °C to +120 °C
Temperature range water: +3 °C to +50 °C
Temperature limits:
Maximum inlet flow: See performance data for each model
Inlet pressure: Min. 20 bar (290 psi), max. 200 bar (2900 psi)
Note: Outlet pressure must never exceed 800 bar (11600 psi ), except for the HC7, HC8 + HC9
Filtration: 10 micron nominal; max. 19/16 according to ISO 4406

Advantages summarised:
Typical clamping circuit
0-103 Model - Example with single-acting cylinder
The HC2 is used to boost the pressure in an existing hydraulic circuit, e.g. in a machining centre to ensure a sufficient clamping force. As the HC2 can be directly fitted into the workholding system, high-pressure connections can be avoided.
Applications with larger flowrates
0-104 Model - Example with external pilot-operated check valve
In applications where the pump supplies a flow exceeding the maximum permissible supplied flow to the HC2, the HC2 is installed in parallel with a pilot-operated check valve. This check valve is dimensioned to allow for all the flow supplied from the pump. The inlet flow to the HC2 is limited to the maximum permissible flow for the particular intensification ratio.
As the cylinder moves forward, all the flow from the pump is used. When the pump pressure is established in the cylinder the check valve closes, and the end pressure builds up through the HC2. The cylinder is retracted by changing the position of the directional valve, whereby the pump is connected to the other side of the cylinder and the DV opens, allowing the fluid to return to the tank.
