Weir Minerals products have a deserved reputation for extended wear life
and reliability, bringing the customer the lowest cost of ownership.
Weir Minerals is the worlds leader in the field
of premium quality slurry pumps, slurry valves,
hydrocyclones and mill liners where applications
typically involve heavy abrasive and/or corrosive
slurries that make severe demands on the
equipment used.
The strength of Weir Minerals products lies in the
superiority of our hydraulic designs and wear and
corrosion resistant materials.
To maintain this number one position Weir Minerals
has invested heavily in an ongoing programme of
research and development focussed on the areas of
hydraulic design, materials technology and
shaft sealing.
The pumps are renowned for innovative designs
for heavy duty submersible slurry pumps used in
aggressive abrasive applications.
During the design process of the SHW heavy duty
submersible slurry pump, extensive use was made of
finite element stress analysis software in conjunction
with unigraphics solid modelling to ensure maximum
mechanical integrity of the major pump components.
Combined with the use of an A05 28% high chrome
alloy wet end mounted on a heavy duty iron motor
housing, the SHW represents the most dependable,
long lasting, submersible pump available.
This dependability results in the lowest cost of
ownership.

Design features of the SHW Heavy Duty,
All Chrome, Double-Sealed, Submersible
Slurry Pump
A - Advanced Cable Entry
The advanced cable entry offers double protection
against moisture. The power and control cables enter
through individual cable glands that act as strain
relief while sealing the cable jacket. Both cable cores
are also sealed using barrier connector embedded in
epoxy sealant.
B - Heavy-Duty Thrust Bearings
C
High-capacity, angular contact duplex bearings are
generously sized to handle thrust loads associated
with high specific gravity slurries.
C - Temperature Sensor
Over-temperature sensors protect the motor by
sounding an alarm or shutting down the unit if
internal temperatures exceed safe operating limits.
D - Moisture Detector
A twin electrode system provides double protection
by detecting moisture intrusion in either the motor
housing or the mechanical seal chamber.
E - Mechanical Seals
The SHW incorporates 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.

F - Heavy-Duty Water End
E
Standard 28% chrome construction coupled with
heavy section thickness provides the ultimate in
protection against abrasive wear in heavy slurries.
G - Easy Maintenance Access
T-bolt construction allows rapid disassemble 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.

H - Optional Robust Agitator
A robust agitator can be fitted to the suction eye
allowing the pump to handle high concentrations
of solids.
