Verderair Air-operated Double Diaphragm pumps

 

Why Air Operated Double Diaphragm pumps?

Air-operated diaphragm pumps are reciprocating pumps, where the working elements are flexible diaphragms. At least two valves, one on the discharge and one on the suction side, are necessary. 

Leak free air operated diaphragm pump

Air-operated diaphragm pumps are leak-free, owing to the fact that they have no plungers or piston rods, which pass through the pressure boundary. Leakage can; however, occur if the diaphragm breaks. It is; therefore, necessary to replace the diaphragms as part of a preventive maintenance programme, in order to avoid breakdowns. If necessary, double diaphragms can be placed with rupture detection systems on the primary diaphragm.

Variable flow

By simply adjusting the air supply, the double diaphragm pump will provide variable flow and discharge pressures of up to 8 bar. The compressed air can be used to balance liquid pressure and provide high discharge capability. A single pump can provide a broad spectrum of pumping capabilities, ranging from a few litres up to 1,060 l/min.

Dry running capabilities

Air operated double diaphragm pumps are designed to run dry indefinitely without damage, and are self-priming from a dry start. The Air Operated Double Diaphragm pump can also run completely submerged or installed with flooded suction. No packing glands are needed, and there are no close-fitting, sliding or rotating parts to maintain.

Capabilities

As flow and discharge of the air operated diaphragm pump is infinitely variable, one pump can be used for a diverse range of applications. This eliminates the need for costly motor drives and critical calculations.
