Checking the direction of rotation
DANGER
Temperature increase resulting from contact between rotating and stationary
components
Explosion hazard!
Damage to the pump set!
▷
Never check the direction of rotation by starting up the unfilled pump set.
▷
Separate the pump from the motor to check the direction of rotation.
WARNING
Hands or objects inside the pump casing
Risk of injuries, damage to the pump!
▷
Never insert your hands or any other objects into the pump.
▷
Check that the inside of the pump is free from any foreign objects.
CAUTION
Incorrect direction of rotation with non-reversible mechanical seal
Damage to the mechanical seal and leakage!
▷
Separate the pump from the motor to check the direction of rotation.
CAUTION
Motor and pump running in the wrong direction of rotation
Damage to the pump!
▷
Refer to the arrow indicating the direction of rotation on the pump.
▷
Check the direction of rotation. If required, interchange any two phases to
correct the direction of rotation.
The correct direction of rotation of motor and pump is clockwise (seen from the
motor end).
1. Start the pump set and stop it again immediately to determine the motor's
direction of rotation.
2. Check the direction of rotation.
The motor's direction of rotation must match the arrow indicating the direction
of rotation on the pump.
3. If the motor is running in the wrong direction of rotation, check the electrical
connection of the motor and the control system, if necessary.
