A Double Acting positive displacement pump with a directly coupled, integral linear reciprocating air motor. Compact in size, minimal weight and ability to operate in many environments.
Double Acting Series
Hydratron Double Acting Series Air Driven Liquid Pump is a double acting reciprocating, positive displacement pump with a directly coupled, integral linear reciprocating air motor designed to generate High-Pressure Liquid flow.
The pressure increase is made possible by means of the area ratio between the larger diameter air drive piston directly connected to two smaller diameter liquid plungers. Using our various material & seal options they are suitable for pumping a wide range of liquids including water, oil, water/glycol and many other chemical fluids. All Models can easily be incorporated into easy to operate Standard System hydraulic power units.
