Introduction of pneumatic air drive diaphragm pump

GEC air-operated pneumatic fep pump features in design with simplicity and high reliability, which enable the whole serial products with most reliability in any applications.

 

Its reversing valve is a three-dimensional pilot valve that ensures “no sticky” in a true sense. All parts can be replaced without opening the fluid cavity. Aluminum parts are treated with anodic oxidation and epoxy coating which can resist corrosion from unclear air.

Wide Application

Advantages

* Robust and compact slider with Derlin material in reversing valve makes sure it could be used in the situation of bad air source.

* Smooth air course and the sizes of air inlet range from 1/2” to 3” with absolutely no obstacle, which guarantees to change directions easily.

* 100% external maintained reversing valve.

* Less moving parts.

* No need to lubricate reversing valve.

* Long mechanical life of Pilot-type reversing valve guarantees its stable running.

* One reversing valve is suitable for various pumps.
