Product Description

Pneumatic diaphragm pumps, equipped with simple and highly reliable air reversing valves, realize the largest reliability under all kinds of applications. An air reversing valve, a three-way pilot valve, can ensure absolutely no viscosity. All parts can be replaced without the need in opening of hydraulic chambers. Aluminum parts, through anodic oxidation treatment and epoxy coating application, can resist to corrosion by unclean air.

Application Scope
Petrochemical, environmental protection, water treatment, food, pharmacy, paper-making, daily chemical, chemical fiber coating, mining, fire-fighting, agriculture, vehicle-mounting, etc.

Product Features
· A reversing shaft in integral structure ensures concentricity and renders more smooth action;
· A filter ensures normal operation of air motor;
· A ceramic or SS guide block can fit all kinds of service conditions;
· A piston end cover in screw-free structure can be easily installed;
· An external air motor can be easily maintained;
· Engineering plastics are used, thus realizing resource conservation;
· Compared with other diaphragm pumps, a pneumatic diaphragm pump involves few moving parts;
· A same-type reversing valve fits pumps of different specifications;
· An air valve has 15-year quality assurance and a pump has 5 years quality assurance.
