Weir Minerals has unveiled the second generation of the Warman WGR slurry pump as part of the company’s commitment to continually reduce total cost of ownership of its equipment.
The pump was officially launched at Weir Minerals plant in Yateley, county Hampshire, southern England.
The second generation Warman WGR slurry pump (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 Linatex rubber and housed in robust casing halves.
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 as 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 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.
