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.
The R-HDSsw pump incorporates a 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 thrust bearings and shaft are designed to eliminate shaft deflection problems in high density slurries.
A twin electrode system provides double protection by detecting moisture intrusion in both the motor housing and the mechanical seal chamber.
Winding thermostats protect the motor by sending a signal to a customer-supplied relay that can be used for sounding an alarm or shutting down the unit if internal temperatures exceed safe operating limits.
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 provides protection against movement during reverse rotation.
The R-HDSsw pump has a unique combination of features not found in any other submersible slurry pump.
