Air driven liquid pumpsIdeal for hydrostatic testing with water or oil

Air driven liquid pumps convert compressed air into hydraulic pressure (up to 80.000 psi). No electrical connection or lubrication is required.

Hydraulic outlet pressure is equal to the drive air pressure multiplied by pump pressure ratio. Once the high pressure air-driven pump reaches the pre-set pressure it will automatically stall and maintain the pressure. In case of a pressure drop downstream, pump will automatically start and run.

High performance air-driven pumps, to provide an highly safe, reliable and long lasting hydraulic power source for applications up to 68.000 psi (4.688 bar).

These pumps are built to run at their maximum rated pressure and feature a robust motor and seal design that delivers a long lifetime. Moreover, they do not require a lubricated air source and incorporate several features to facilitate easy installation and service.

These pumps reach a “bubble tight” pressure stall that can be used for high pressure applications such as: valve actuation, hydraulic power units, bolt tensioning, jacking, lifting, power pressing, pressure testing and proof testing components, work holding and clamping, power pressing, proof testing components, hydraulic cylinder actuation, chromatography, lubrication and spraying, liquefied gas transfer.
