Pump secondary seal
Abstract:
A centrifugal pumps secondary seal is disposed between the pump housing cover (130) in the seal chamber and includes a rotatable annular slinger (440) axially disposed on the pump motor shaft for slinging water away from the motor shaft and a flange protector (300) with a drain (400, 430) for diverting and directing free liquid from the seal chamber and outside the motor and pump housing (130, 230), thereby preventing corrosion of the seal chamber components, such as the motor flange (230), drive shaft and other motor components, due to exposure to water.
