A Double Airhead Double Acting reciprocating, positive displacement pump. Compact in size, minimal weight and ability to operate in many environments.
Double Head Double Acting Series
Hydratron Double Airhead Double Acting Series, Air Driven Liquid Pump, is a 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 two larger diameter air drive pistons 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.
