SHW-R

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.

Warman® SHW-R features
•t Vortex design allows the SHW-R to pump any
solids that pass through the pump suction, even
stringy, fibrous or tramp material
•t Recessed impeller provides long wear life on heavy
slurry applications
•t The SHW-R handles much higher concentrations of
air than centrifugal pumps
•t Particle degradation is greatly reduced since
pumped solids do not pass through the impeller
•t Temperature Sensor – Over-temperature sensors
protect the motor by sounding an alarm or
shutting down the unit if internal temperatures
exceed safe operating limits
•t Moisture detector – A twin electrode system
provides double protection by detecting moisture
intrusion in either the motor housing or the
mechanical seal chamber
•t 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
•t 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
•t 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
