The series VA80 double diaphragm pumps has been added to the Verderair family from Verder. The pumps are available in three material options: SS316, aluminium and polypropylene, and nine materials are offered for ball valves, seats and diaphragms.

The VA80 pump series is equipped with a quick-acting air valve, enhancing the pump’s efficiency and dispensing with the need of any ancillary equipment to improve efficiency. The complete air valve consists of only 13 parts, including the housing.

The air valve is externally serviceable, requires no lubrication, nor oilers, and can be serviced in five minutes. The VA80 air valve also has the ability to be repaired offline.

Features of the new pump series include:

• Smooth and rapid change over (quick-acting air valve)

• More efficient operation (Higher flow rate, yet less air consumption)

• Less maintenance; less downtime (cost savings)

• Leak-free operation (safe and reliable)

• Increased material strength

The rigid 4-bolted construction ensures equal sealing pressure for the total sealing surface and offers leak-proof pumping.  The polypropylene model is provided with an overmolded fluid section frame to have a better relaxation on the joints and to enhance the strength of the fluid section.

The pumps offer flow up to 1135l/min and pressure up to 8.6 bar. Corrosive and abrasive resistance comes as standard.
