Second generation slurry pump

18 October 2017

In line with Weir Minerals’ commitment to reducing total cost of ownership of its equipment, the company is launching the second generation of its Warman WGR pump.

The new pump features fully replaceable liners designed using Computational Fluid Dynamics (CFD) simulation that is said to provide a significantly improved performance over the first generation WGR pump. Liners and impeller are manufactured from premium Linatex rubber and housed within robust casing halves. Enhancements to the casing design simplify maintenance and minimise downtime. Other new features include the introduction of an expeller gland seal for optimum performance, as well as the option of a low flow packed gland, and a special D gland seal.

The rugged design of the WGR pump makes it suitable 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 sizes from 35 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;
  • Large diameter expeller seal to protect against high inlet pressures;
  • Replaceable premium Linatex rubber liners;
  • Simplified wet end design with fewer parts  for ease of maintenance;
  • Lifting points added to aid safe handling of heavy castings;
  • Axial impeller adjustment to maintain the gap to the throatbush, reducing recirculation wear.

Harvinder Bhabra, Weir Minerals Europe’s senior product manager for pumps, says: “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.”
