Weir Minerals launch second-generation Warman pump

Warman WGR pump

Latest WGR pump offers enhanced performance, reduced downtime and increased safety  

IN line with Weir Minerals’ commitment to continually reduce the total cost of ownership of their equipment, the company has launched its second-generation Warman WGR pump.  

The latest pump boasts several new features, including fully replaceable liners designed using computational fluid dynamics (CDF) simulation, that provide a significantly improved performance over the first-generation WGR unit.   

The liners and impeller are manufactured from premium Linatex rubber and housed within robust casing halves. Enhancements to the second-generation casing design simplify maintenance and minimize downtime, thanks to a wet-end design and fewer parts for servicing. 

Other new features include: an expeller gland seal for optimum performance; and the options of having a low-flow packed gland or a unique 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 in mineral processing. 

Available in seven different sizes – from 35mm to 250mm – the Warman pump includes:  

  • Impelle 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
  • Lifting points added to aid safe handling of heavy castings
  • Axial impeller adjustment to maintain the gap to the throatbush which, in turn, reduces recirculation wear.

Harvinder Bhabra, senior product manager for pumps at Weir Minerals Europe, 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. 

‘The second-generation Warman WGR pump offers exceptional performance, reduced downtime, more safety features and a lower cost of operation.'
