High Pressure Equipment

Double Head Double Acting (DHDA) Liquid Pump

A Double Airhead Double Acting reciprocating, positive displacement pump. Compact in size, minimal weight and ability to operate in many environments.

Product Details:

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.

Key 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.
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.

Suitable for 6,700 to 30,000 PSI
