Verderhus Screw Channel Pumps

Verderhus Screw Centrifugal Pumps

The Verderhus Screw Centrifugal Pump has an open channel impeller design, when combined with the centrifugal force offers high flow rates and huge efficiency.

The Verderhus Screw Centrifugal Pump also features:

high efficiency, BEP > 70%
handle solids up to < 30% slurry
flow range max 1500 m³/h
minimal clogging, also when pumping long fibred fluids
capable of pumping high viscous fluids up to 3000 cPs
suitable for gas containing media
low energy cost, almost constant - also at high flow rates
oil lubricated double mechanical seal

APPLICATIONS

These pumps are used in a wide range of industries including:

Water treatment: thick sludge, thickened media, slurries, sewage and waste water

Pet food
Breweries & malteries
Waste burning power station

PRODUCT INFORMATION

The Verderhus screw centrifugal pump combines the best features of centrifugal and positive displacement pumps to define a new standard for low head, high flow pumping. These pumps have a large clearance, screw impeller gently feeding product into the pump chamber and efficiently transferring it to the discharge line. The open impeller allows large solids to be easily pumped, whilst the screw design is ideal for high solid contents or viscous liquids and produces high efficiency, low NPSHr pump, lowering both energy use and ownership costs.
