Weir Minerals Europe launches the first Warman® vortex pump

Weir Minerals Europe has launched a new addition to its Warman® range of centrifugal pumps - a vortex pump featuring an open, recessed impeller designed to minimise abrasion, clogging and damage to delicate materials.

Unlike standard centrifugal pumps, the Warman® WRR® pump uses a vortex to move slurry through the unit, created by an impeller which sits outside of the main flow path. This provides an unobstructed passage between suction and discharge, even for particles as big as the suction inlet.

The Warman® WRR® pump is designed for applications across the wastewater, food and drink manufacturing, mining, minerals and chemical processing industries.

The WRR® pump is available in a large range of sizes and configurations including standard horizontal, close coupled, submersible and vertical bearingless designs. Flow rates range from 1 to 1250 m3/h and free spherical passages from 40 to 250mm.

Tony Lawson, engineering director at Weir Minerals Europe, said, “The Warman WRR pump features similar technology to Wemco vortex pumps, which have been available in France for many years.

"There are many applications for clog-free pumps offering free passage to large particles across many industries, from transporting large volumes of vegetables and other food products without damage, to the carbon-in-pulp transfer process used in gold, copper and silver mining.

"The WRR model pump features the high quality of build and materials for which our Warman range is known across the globe. It is available in a range of materials suitable to the level of abrasion resistance required by the application, and is supported by our Weir engineering expertise and extensive aftermarket support network."
