PREPARATION FOR START-UP
PUMP SUPPORT
Before starting a newly installed pump, check the pump
supports and piping to be certain that they conform to the
specifications in the ‘Installation’ section of this manual.
BEARING LUBRICATION
The bearings must have adequate lubrication. The bearings
were properly filled with grease prior to shipment.
Regrease bearings if pump was disassembled. Refer to the
Maintenance of Bearings section.
SHAFT ROTATION
The pump shaft must turn without any binding or rubbing -
only the uniform frictional drag of the bearings should be
felt. If the pump does not turn freely by hand, check to
determine the cause of the binding.
CORRECT DRIVER ROTATION
$
CAUTION
Incorrect rotation could result in considerable damage
to the pump. Check the motor rotation when motor is
not connected to the pump shaft.
The direction of rotation of the driver must be checked
before it can be coupled to the pump. The correct direction
of rotation of the pump is indicated on the bearing frame.
Since the impeller is threaded on, reverse rotation could
cause the impeller to unscrew from the shaft.
s
! WARNING
Lock out driver power to prevent accidental start-up
when working on drive.
1. Lock out power to driver.
2. Disconnect coupling from the driver or the belts from
the drive. Make sure no parts are loose.
3. Unlock driver power.
4. Make sure everyone is clear of driver. Jog the driver
just long enough to determine the direction of rotation.
Rotation must correspond to the arrow on the pump.
5. Lockout power to driver and reinstall coupling or
belts.
6. Reinstall coupling or belt drive guard.
PRIMING
The liquid level must be above that shown on the
dimensional drawing supplied with the order.
