Air diaphragm pumps prove reliability.

Experience at Akzo Nobel led to the specification of over 100 Verder air diaphragm pumps for their new plant: 2.5 years later they are still maintenance free.

Akzo Nobel Inks use over one hundred Verderair air diaphragm pumps at their new ink production facility in Manchester.

These pumps have been in continuous operation since they were installed two and half years ago and remain maintenance free.

Staff at the plant have commented on the excellent performance of the units and are impressed with the level of technical support they have received from Verder.

Pumps in the same range were used at the Akzo Nobel previous site and performed so well that they were specified for the new plant.

They perform a variety of dosing and bulk transfer duties and handle solvents, process fluids and printing inks of varying viscosity.

VA40 pumps (1.5") in Aluminium service the tank farm while VA25's (1") in Polypropylene are incorporated in the ink machines.

The pumps are ideally suited to conveying the flammable liquids used at the plant, as they are seal-less, leak-proof and present no electrical hazard.

In addition to the fixed units installed at the site, Akzo also make use of trolley-mounted pumps to off-load product from tankers.

With their efficient, low leakage air valves, these pumps have demonstrated the cost savings that Verderair products can achieve through reduced air consumption and a high displacement rate per stroke.

By standardising on these pumps, Akzo will benefit from lower life cycle costs.

The VA25, 40 and 50 models share a common air valve that requires no lubrication, comprises just nine parts and can be serviced without disconnecting the pump.

Other makes of air diaphragm pump typically use air valves that are specific to one pump size, feature many more parts and need servicing more regularly.
