Verder completes pump line with new range

Verder has introduced the Verderair Hi-Clean range of air operated double diaphragm pumps. The Hi-Clean range is suitable for where pumping processes require FDA, 3A and EC1935/2005 compliant specification.

The pumps are constructed from SS316 stainless steel polished to RA 3,2μm. The centre section is also available in aluminium and PP for where a full SS316 is not required.

The range also features a piston-type pump for direct insertion into IBCs, barrels and other containers for hygienic transfer.

At the heart of the pump is the air valve. The Verderair valves are responsive and fast-acting so all of the air is used to push the fluid with no waste. The air valve reduces the total amount of air needed to move a set volume of fluid. The operating volume and vibration is also reduced, contributing to a better working environment.

The pump range is CIP and SIP compatible and is specially designed to be disassembled with a simple clamp arrangement. The flanges are available in tri-clamp or DIN 11851 configurations for crevice-free connection. The air valve is encapsulated which allows the pump to be jet washed.

The design allows the strip, inspection and service in less than 20 minutes.

Hi-Clean pumps can deliver a flow rate of up to 568L/min and up to 20,000cPs. The positive displacement of the moving diaphragms is a gentle, low-shear pumping principle, which preserves the often delicate structure of the fluid.

Models are available with ball vales or flapper types to permit solids of up to 63.5mm.

Suitable fluids include viscous pasta sauces and pastes, milk and dairy, beers, wines and juices as well as personal care products such as creams, gels and shampoo.

The working principle of an air diaphragm pump allows the flow path to run dry without damage and is true self-priming. Selected models also feature over-moulded diaphragms and leak detection sensors for 3A compliance for minimal disruption to the process line.
