VERDERAIR DOUBLE DIAPRHAGM PUMPS Verderair double diaphragm pumps are used with a variety of fluids. These pumps are the best solution for applications that are of abrasive or corrosive nature. Also very sticky and viscous liquids, or liquids containing solids can be handled without problems. The quick acting air valve technology is making these pumps the most efficient diaphragm pump series on the market. How does a double diaphragm pump work? An air operated double diaphragm pump has two diaphragms. These diaphragms are connected by a shaft in the center section. The diaphragms are working...

The air behind diaphragm number two is being pushed out to the atmosphere. Atmospheric pressure pushes the liquid to the suction side. The suction ball valve is being pushed away off its seat. This allows the fluid to flow along the ball valve into the liquid chamber. When the pressurized diaphragm number one has reached the end of its stroke, the movement of the air is switched from diaphragm number one to the back of diaphragm number two by the air valve. The compressed air pushes diaphragm number two away from the center block. Doing so, diaphragm number one is pulled toward the center block....

THE HEART OF YOUR DOUBLE DIAPHRAGM PUMP: THE AIR VALVE General features ✓ Non-stalling ✓ No air lubrication needed ✓ Easy maintenance ✓ No freezing The heart of your double diaphragm pump is the air valve. Comparable with the heart of the human body, the efficiency of your diaphragm pump is depending on the quality of air valve of the pump. Sometimes your pump has to run slow and steady for a long period, sometimes you want a quick fluid transfer. With this in mind, VERDERAIR has developed 3 different kind of air valves, with their specific features, to make the best out of each air operated...

VERDERAIR MATERIALS TO CHOOSE FROM To meet most severe processes To meet your most severe process conditions, yet still having a trouble-free operation, Verderair pumps have nine different material options for the valve seat, diaphragm & balls. The combination of these high quality materials together with the choice of different pump materials give the optimum pump selection. Acetal – Wide range of solvent resistant and withstands extreme fatigue. Good level of abrasion resistance. Electrically conductive (ATEX). antoprene – Good resistance to abrasive and chemical fluids. S Santoprene is compatible...

The Verderair PURE double diaphragm pump series is a robust series of double diaphragm pumps, produced from one-piece solid material. The Verderair PURE is designed for heavy-duty operation, also for harsh liquids and severe process conditions, such as operating in power plants and refineries. The Verderair PURE has all the benefits of a Verderair double diaphragm pump such as increased productivity through a higher flow rate and reduced operational cost because of lower air consumption. On top of that the PURE series has an extended program of accessories. Thanks to the efficient operation less...

VERDERAIR PURE PULSATION DAMPENERSTo reduce a pulsed flow Due to the function principle, air operated double diaphragm pumps are generating a pulsating flow. By using a Verderair pulsation dampener in combination with the pump, the flow pulses will be reduced to the minimum. The Verderair pulsation dampeners are active dampeners and achieve the best possible dampening effect to create an almost flat flow. Materials for Verderair PURE and PURE Pulsation Dampeners Polyethylene (PE) Extremely abrasion resistant. Upto 7 times better than Polypropylene. Chemical resistance is compatible to Polypropylene....
