Designed in accordance with API 610 standard, these heavy duty centrifugal pumps are designed for petrochemical, oil refinery and liquid natural gas applications. Available with bearing cooling, seal flush and auxiliary monitoring systems.
Air operated diaphragm pumps or pneumatic diaphragm pumps are reciprocating pumps where the working elements are flexible diaphragms. The control is by means of compressed air being applied to the Air Valve incorporated into the pump. The air valves’ unique design guarantees a perfect, non-stalling operation, even at low pressure and does not need any lubrication.
Air operated diaphragm pumps are leak free because they don’t have plungers or piston rods which pass through the pressure boundary. A leakage can only occur if the diaphragm, also referred to as the membrane, breaks. In preventive maintenance, or to avoid breakdowns, it is necessary to replace the diaphragms.
The double diaphragm pump will provide variable flow and discharge pressures of up to 870 kPa by simply adjusting the air supply. The compressed air can be used to balance liquid pressure and give high discharge capability. A single air pump can provide a broad spectrum of pumping capabilities from a few litres up to 1,060 l/min.
Air operated double diaphragm pumps have outstanding dry run capabilities. These pumps are designed to run dry indefinitely without damage. The AOD pumps are also self-priming from a dry start. The Air Operated Double Diaphragm pump can also run completely submerged or installed with flooded suction. For ease of maintenance, they don’t require gland packing and there are no close-fitting, sliding or rotating parts to maintain.
As flow and discharge of the air operated diaphragm pump or pneumatic diaphragm pump is infinitely variable (as mentioned above) one pump can be used for an extremely wide range of capabilities. This eliminates the need for costly motor drives and critical calculations.
Besides the general advantages of any air operated double diaphragm pumps on the market, Verderair offers many other advantages for users. Having a wide range of proven products for different applications Verderair offers experience. Verder (diaphragm pump-set manufacturers) has over 50 years of experience with applications for the air operated diaphragm pump. This experience comes from both the industrial and sanitary segments.
Generally, people expect Air Operated Double Diaphragm pumps to be available on a short term. Therefore Verderair works with an efficient stock-management (for both pumps and parts) and flexible production. With this, Verderair offers a real advantage if you need a pump within a short time frame.
