The Hydraulic Power Supply provides clean oil to the die gap tooling actuator at a constant supply pressure. An accumulator provides the peak flows that may be required. A water heat exchanger ensures reasonable oil temperatures.

The Hydraulic Power Supply is normally used on first installations when the cleanliness condition of the blow molding machine’s hydraulic power supply is unknown or suspect. A separate hydraulic power supply provides a reliable source of clean oil for trouble free long term operation. A bypass filter allows the oil to be continually cleaned and cooled.

The hydraulic power supply pressure output should be connected directly to the input port of the high pressure filter at the die gap tooling actuator or the servo valve manifold. The actuator or manifold return line goes to the hydraulic power supply return port.
