IX. Operation
Before Starting
Before starting work on the pump, make sure that the pump is isolated from the
power supply and cannot be energized.
Make sure that the pump cannot roll or fall over and injure people or damage
property.
Check that the visible parts on the pump and installation are undamaged and in good
condition.
Check the oil level in the oil housing.
Remove the fuses or open the circuit breaker and check that the impeller can be rotated
freely.
Check that the monitoring equipment (if any) works.
Check the direction of rotation. The impeller shall rotate clockwise, as viewed from above.
When started, the pump will jerk in the opposite direction to the direction in which the
impeller rotates. See the figure.
In the case of dry installation, check the direction of rotation through the inlet elbow access
cover.
Transpose two phase leads if the impeller rotates in the wrong direction (3~).
In some installations the pump surface and the surrounding liquid may be hot.
Bear in mind the risk of burn injuries.
Starting Jerk
Watch out for the starting jerk, which can be powerful.
