A pneumatic pump’s robust design will efficiently convert compressed air into hydraulic power, satisfying any application need for pressurizing up a component and holding it at a set pressure for any sustained period of time.Backed by a global network of high-pressure expertise, service and support, our pneumatic pumps are consistently recognized as the most reliable in the industry.
Air Driven Liquid Pumps are air driven at a drive air pressure of 1bar to 8bar (14.5 psi to116 psi) by the normal air compressor. Basically the principle of operation is similar to a reciprocating amplifier where control of the piston at the end position is regulated by a pilot operated 4/2 way valve.
Air Driven Liquid Pump feature a large air piston joint to a smaller diameter plunger. The pressure ratio is the difference of these two areas and is the method of determining maximum outlet pressure. Higher pressures obtained by using higher pressure ratios.Suncenter model numbers reflect the pumps nominal pressure ratios, while the technical data indicates exact ratios. The outlet pressure is easily to set through a simple air regulator. By multiplying the pressure ratio by the available shop air pressure, the nominal liquid pressure can be calculated.
