PREPARATION FOR OPERATION
CHECKING ROTATION
When installing in a potentially explosive
environment, ensure that the motor is
properly certified.
Damage occurs
from:
1. Increased vibration levels-affects bearings, stuffing
box or seal chamber and mechanical seal
2. Increased radial loads Stresses on shaft and
bearings
3. Heat build up-Vaporization causing rotating parts to
score or seize
4. Cavitation-Damage to internal surfaces of pump
CAUTION
Serious damage may result if pump is run in the
wrong direction.
WARNING
Lock out power to prevent accidental start-up and
physical injury.
Serious damage may result if the pump is
run in the wrong direction.
A check must be made to be sure motor rotation
coincides with the pump rotation direction. Depending
on your pump arrangement (V-belt or
gear-drive) use one of the following methods to check
motor rotation.
Direct Connect
1. Lock out power to the driver.
2. Remove the pump coupling guard.
3. Make sure the coupling halves are securely
fastened to shafts.
4. Unlock driver power.
5. Make sure everyone is clear. Jog the driver just
long enough to determine direction of rotation of
the output shaft of the gearbox. Rotation must
correspond to an arrow on bearing housing.
6. Lock out power to driver.
7. Replace the pump coupling guard.
The coupling guard used in an ATEX
classified environment must be constructed
from a non-sparking material.
V-BELT
1. Lock out power to the driver.
2. Remove the V-belt guard.
3. Make sure the sheaves are securely fastened to
shafts.
