Verderair Industrial Air Operated Diaphragm Pumps
General
Under all circumstances Verderair air operated diaphragm pumps are taking care of a smooth and reliable transport of liquids. The unique design of the air valve guarantees a perfect and non-stalling operation.
The pump is simple by design: its construction allows it to undertake arduous tasks that other pumps would not be able to handle which means less maintenance and therefore reduced life time costs. The pumps’ simplicity offers high interchange ability across the comprehensive range.
The pump is easy to use - flow can be achieved on demand and altered by simple air or fluid regulation.
Right across the range, displacement per stroke is high; this substantially increases the life of the pump, reducing the maintenance and lifetime costs.
Verderair offers a complete range of air operated diaphragm pumps for a wide range of applications in almost all industries.
Models
Verder has chosen a wide variety in materials to offer solutions for the complete industry. We make a difference between housings in non-metallics and metallics.
Verderair are highly engineered diaphragm pumps, delivering a smooth, reliable flow at all circumstances. The new air valves design guarantees a perfect, non-stalling operation, even at low pressure and does not need any lubrication. Thanks to their unique design, they are able to handle very abrasive and / or viscous products.
The Verderair will run dry indefinitely without damage. Verder has selected those materials which offer the best combination of benefits to the end user. The used wetted pump part materials are Acetal, Polypropylene, Kynar, Aluminium, Cast Iron and Stainless Steel. For ball and /or diaphragm, VERDER selected PTFE, Hytrel, Santoprene, Viton, BUNA-N, SS and Acetal.
NEW - Atex: Verderair offers now pumps in a conductive polypropylene housing. With this unique material you can benefit from the polypropylene-advantages in an Atex environment.
The flow range is from 0.1 up to 1,060 l/min and pressures up to 8 bar (or 16 bar for high-pressure models).
