Double Acting Series Hydraulic Pumps
A Double Acting positive displacement pump with a directly coupled, integral linear reciprocating air motor
The Hydratron DA 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.
Hydratron’s DA Series Double Acting Air Driven Liquid Pumps offer many desirable features:
- Ability to stall at a predetermined pressure and hold this fixed pressure without consuming power or generating heat.
- No risk of flame or spark.
- Infinitely variable speed/output flowrate control.
- Infinitely variable output pressure control.
- Easy to apply automatic controls.
- Standard models are suitable for oil or water applications.
- X-type Isolation chamber for Chemical applications.
- No limit or adverse effects in continuous stop/start applications.
- Proven reliability, easy to maintain and robust.
Mainly Anodized Aluminium, Stainless Steel and nitrile seals.
Aluminium Bronze, Stainless Steel and Nitrile seals are standard (other compounds are available as required). All hydraulic pistons are hard chrome plated. Other material options are available, please contact our office for more information.
