Info

These pressure intensifiers increase a hydraulic pressure in a fixed ratio. With this method, for example, machine hydraulics with a low pressure can be used for consumers that use a much higher pressure economically. The pressure intensification takes place via a fixed surface ratio of two piston surfaces. This allows the secondary pressure to be controlled via the inlet pressure. A bypass non-return valve is provided for rapid filling of the hydraulic consumers. The pressure intensification starts automatically at approx. 20 bar. The oscillating pumping process starts automatically when a volume flow passes through the pressure intensifier. The pressure intensification ends automatically when the consumer no longer requires a volume flow and the high pressure is reached. The volume flow on the high pressure side depends on the high pressure reached. The higher the high pressure reached, the lower the volume flow.

Operating conditions:
It is recommended that apressure filter with a maximum filter fineness of 10 µm is installed upstream of the low-pressure connection. Due to the design of these pressure intensifiers, an internal leakage occurs which is automatically discharged. For uncoupled consumers, it is recommended that an additional pilot-operatednon-return valve is fitted between the pressure booster and the consumer. This can be controlled to open via the T-line.
