Submersible vortex pump
max. 2 000 gpm | SHW-R series Weir Minerals

- 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
