The pump was officially launched at Weir Minerals plant in Yateley, county Hampshire, southern England.
The second generation WGR pump boasts several innovative features including fully replaceable liners designed using Computational Fluid Dynamics (CFD) simulation that provide a significantly improved performance over the first generation WGR pump.
The liners and impeller are manufactured from premium
Enhancements to the casing design are said to simplify maintenance and minimise downtime, while other new features include the introduction of an expeller gland seal for optimum performance, as well the option of having a low flow packed gland and the special D gland seal.
The company says that the rugged design of the WGR pump makes it ideal for use in the production of sand and aggregates, as well as other applications within mineral processing, coal preparation and power sectors and general industrial applications.
Available in seven different sizes, from 35mm to 250mm, the Warman WGR pump includes wear components that are optimised using the latest technology; impeller and volute liners designed to reduce turbulence and deliver longer wear life; high-capacity bearings to withstand high loads, and large diameter expeller seal to protect against high inlet pressures.
The pump also includes replaceable premium Linatex rubber liners; simplified wet end design with fewer parts for ease of maintenance, and lifting points added to aid safe handling of heavy castings. An axial impeller adjustment maintains the gap to the throatbush, reducing recirculation wear.
Harvinder Bhabra, Weir Minerals Europe’s Senior Product Manager for Pumps, said: “We have used the very latest technology to produce a pump solution that will be a leader in its class.
“Slurry pumps are central to modern extraction processes so must be reliable and cost-effective. Our second generation Warman WGR pump combines exceptional performance, reduced downtime with added safety features and a lower cost of operation.”
The improved Warman WGR pump will be released to the European market in October 2017 and launched worldwide later in the year.
