Seal Guard
Seal guards (shown below) are available when all rotating shaft components must be covered.
This option is required for all CE pump models.
When ordered, the pump will be shipped with the seal guard installed. The seal guard is sup-
plied with captive fasteners to secure the guard in place.
Prior to startup, ensure that the guard has not been removed, damaged, or loosened during trans-
portation, loading/unloading, installation, etc.
Never loosen or remove the seal guard during operation.
Before removing the seal guard for pump maintenance, de-energize the motor, lock out the mo-
tor controller/start and place a caution tag at the starter indicating that it is disconnected. Before
resuming normal pump operation, replace the seal guard.
For maintenance, the guards can be removed by loosening the captive fasteners.
