Description:

The HC63 is a high-flow unit which is capable of delivering up to 64.5 l/min flow on the high-pressure end. Like other miniBOOSTER models, the HC63 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 HC63 is a compact unit weighing only 60.0 kg.

HP flange mounting is optional. Furthermore, it is possible to flange multiple HC63 boosters in order to achieve higher flow.

General Function:

The basic operation is illustrated in the function diagram. Oil 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.

Minibooster HC63 Flow RatesMinibooster HC63 Connection Types

Minibooster A Model

Without Dump Valve

High pressure is relieved externally. This is achieved in most cases by the use of a pilot operated check valve.
This is a good solution when there is high return flow from a large bore hydraulic cylinder.

Minibooster B Model

With Dump Valve

Allows the high pressure side to be relieved. When port 'R' is pressurised and port 'IN' is open to tank.
Pilot supply will open the 'DV' valve allowing the fluid from the high pressure side 'H' to flow back to tank

Minibooster G Model

With RV Valve

The RV valve allows you to control the high-pressure side proportionally controlled directly from the low-pressure side.

General Minibooster Specifications

  • High flow - low pressure
  • Low flow - high pressure

flow pressure curve diagram

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:

  • +30 °C to +60 °C = Best performance - long life-time
  • Outside above range = Reduced performance and/or life-time

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:

  • Gives high pressure whenever needed
  • Expensive high-pressure pumps not required
  • Expense saved on tubing
  • Increase expensive high pressure by simply increasing inexpensive low pressure
  • Low pressure is changed into high pressure with hardly any use of energy or heat generation
  • Leakages on the high-pressure side compensated dynamically
  • System works with labyrinthine tubing, which gives a longer life
  • No rotating parts
  • Light weight
  • Small size – high performance

Typical clamping circuit

0-103 Model - Example with single-acting cylinder

Typical clamping circuit

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

Applications with larger flowrates

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.
