Air driven liquid pumps
Ideal for hydrostatic testing with water or oil
Pneumatically operated, no electrical connection required
Air driven liquid pumps convert compressed air into hydraulic pressure (up to 8000 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 Pressure Equipment has also developed the T Series, 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). Combining HiP’s high pressure expertise with Graco’s extensive pump engineering background, T-Series pumps address many of the shortcomings tipically found in today’s air-driven liquid pumps. These pumps are built to run at their maximum rated pressure and feature a robust motor and seal design that delivers a long lifetime.
HiP T-Series pumps do not require a lubricated air source and incorporate several features to facilitate easy installation and service. HiP T-Series 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.
T-Series is available with Graco Datatrak electronic monitoring system
