Features of AODD Pumps
- Pump is simple by design: highly interchangeable and less maintenance and therefore reduced life time costs.
- Pump is easy to use; flow can be achieved on demand and altered by simple air or fluid regulation.
- Displacement per stroke is high; this substantially increases the life of the pump, reducing the maintenance and lifetime costs.
Why AODD-pumps?
Air operated diaphragm pumps are reciprocating pumps where the working elements are flexible diaphragms. The drive is by means of compressed air acting directly upon the diaphragm. Another possibility is hydraulically drive instead of compressed air. At least two valves, one on the discharge and one on the suction side, are necessary. Several types of valves are used. The most popular valves are flap, cylindrical and ball valves.
Benefits of AODD Pumps
Leak free air operated diaphragm pump
Air operated diaphragm pumps are leak free since 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 in the course of preventive maintenance 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 provides variable flow and discharge pressures of up to 235 psi. The compressed air can be used to balance liquid pressure and give high discharge capability. A single pump can provide a broad spectrum of pumping capabilities from less than 1 gpm up to 275 gpm.
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 aodd-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 an extremely wide range of capabilities. This elimates the need for costly motor drives and critical calculations.
Short delivery time
Generally people expect aodd-pumps to be available on a short term. Therefore Verderair works with an efficient stock-management (of course for both pumps and parts) and flexible production. With this Verderair offers a real advantage. So if you need a pump with a short lead time please give us a call!
