Advantages of air operated double diaphragm pumps:

Pumps a variety of fluids!
Viscous fluids, corrosive fluids, abrasive fluids, fluids which are sensitive to shear and foaming are just some of the huge range of fluids that can be pumped.

No foaming or shearing of process fluid!
Because of the gentle low velocity pumping action, fluids passing through a Teryair diaphragm pumps are not subjected to high forces and therefore do not foam or shear.

No decline in pump efficiency!
No rotary components or pistons to wear out, pump efficiency generally remains constant over the life of the pump.

No lubrication required and no damage from dry pump operation!
Teryair diaphragm pump valves are constructed with materials that do not need lubrication. And the pump cannot be damaged by dry operation.

Solid particle handling!
Teryair diaphragm pumps can handle suspended solids of considerable size. For e.g. a2” pump will handle solids of up to ¼' diameter.

Completely Submersible!
With proper exhaust venting to atmosphere, Teryair diaphragm pumps are submersible. Process fluid must be compatible with material of construction.

Automatic Stopping of pump with no energy consumption!
Simply closing the discharge valve can stop Teryair diaphragm pumps. even if this valve is at a distance away from the pump. The pump stops without any further air consumption and starts again once the discharge valve is opened.

Similarly the pump is capable of pumping at variable flow rates either by adjusting the supply air pressure or by throttling the discharge side, in both ways the energy consumption is proportional to the pumping volumes.

Easy Maintenance!
One of the best features of Teryair diaphragm pumps is the ability to maintain the pump on site without even opening the foundation bolts and process piping. The air valve and the diaphragms can be maintained and replaced easily in this way.

Cool running, spark resistance and explosion proof!
Teryair diaphragm pumps do not generate much heat during operation and the air circuit through

the pump helps keep the pump at relatively cooler operating temperatures. This removes the possibility of ignition of solvent vapors. Moreover as these pumps are pneumatic there is no possibility of sparking and therefore explosion proof. (Please consult Teryair for installation in potentially hazardous applications)

Portability and easy installation!
The overall small size and lightweight design of Teryair diaphragm pumps makes them easy to move from job to job and install with no major concrete foundation.
