Warman® SHW pump

The design process of the Warman® SHW made extensive use of finite element stress analysis and state of the art solids modeling to ensure rugged, dependable solids handling capability at the 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 the most dependable, long lasting submersible pump you can buy.

Features / Benefits

  • 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 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
    during reverse rotation.
  • Optional agitator – A robust agitator can be fitted to the suction eye allowing the pump to agitate high concentrations of solids.

Optional Features

  • Cooling jacket allows continuous pump operation with the motor completely unsubmerged
  • Suction saver prevents clogging in sumps where tramp material or very large solids are present
  • Quick disconnect guides the SHW into the sump with automatic connection to discharge piping.
  • Discharge elbow in high chrome iron with heavy wall thickness allows for lower cost installation by having the correctly designed and sized discharge elbow for your application
  • Sparger ring designed for your application that allows for improved sump removal of larger solids by spraying high pressure liquid back into the sump
  • Slide bracket allows for easier installation on-site and provides correct positioning of the pump in your sump

Agitator Options

Two different agitator options are offered depending upon solids type.

  • Agitator design option A allows a more complete removal of fine solids.
  • Agitator design option B aggressively agitates larger solids from the sump floor.
