The Weir Group PLC

- Model SHW-R - Submersible Slurry Pump



The design process of the Warman SHW-R made extensive use of state of the art solids modeling to ensure rugged, dependable solids handling capability at lowest possible cost. A heavy duty all chrome wet end coupled with a motor designed and built by Weir Minerals for the most demanding applications makes the Warman SHW-R the most dependable, long lasting, submersible pump you can buy.

  • Size range (discharge)
  • 2” to 6”
  • 50 mm to 150 mm
  • Capacities
  • to 2,000 gpm
  • to 455 m3/hr
  • Heads
  • to 175 ft  
  • to 53 m

  • Vortex design allows the SHW-R to pump any solids that pass through the pump suction, even stringy, fibrous or tramp material
  • Recessed impeller provides long wear life on heavy slurry applications
  • The SHW-R handles much higher concentrations of air than centrifugal pumps
  • Particle degradation is greatly reduced since pumped solids do not pass through the impeller
  • Temperature Sensor – Over-temperature sensors protect the motor by sounding an alarm or shutting down the unit if internal temperatures exceed safe operating limits
  • Moisture detector – A twin electrode system provides double protection by detecting moisture intrusion in either the motor housing or the mechanical seal chamber
  • Mechanical seals – The SHW-R incorporates Warman’s proven balanced double-seal arrangement in which both sets of seal springs are enclosed in the oil reservoir. Silicon carbide seal faces are subject to submergence pressure only for greatly extended wear life
  • Heavy-duty water end – Standard high chrome iron construction coupled with heavy section thickness provides the ultimate in protection against abrasive wear in heavy slurries
  • Easy maintenance access – T-bolt construction allows rapid disassembly of the pump end for maintenance access. The heavy-duty impeller is not screwed on, but keyed to the shaft for easy removal and protection against movement
