KRAL KV - Checking the Direction of Rotation

10 Operation
10.2 Commissioning
DANGER
Magnetic field.
Risk of death for persons with cardiac pacemaker, metallic implant or neurostimulator.
► Under no circumstances may persons with cardiac pacemakers, metallic implant or
neurostimulator perform work on the pump/pump unit.
WARNING
Risk of injury through emitted pumped liquid.
Pumped liquids can be hot, poisonous, combustible and caustic.
► Wear personal protective clothing during all the work. Ensure face protection.
► Collect any discharging pumped liquid safely and dispose of it in an environmentally compatible
manner in accordance with the applicable local regulations.

Requirement:
ü Shut-off devices in the suction line and pressure line closed
1. Remove the screw plug of the vent hole1 so that the air can escape during the filling process.
2. Remove the screw plug of the pressure-side vent hole3.
3. Fill the pump via the pressure-side vent hole3, until the pumped liquid is emitted at the vent
hole1.
4. During the filling process turn the pump shaft or fan impeller of the motor by hand to speed up the
filling process:
Filling of the suction chamber: Turn the pump shaft against the direction of rotation of the motor.
Filling of the sealing chamber: Turn the pump shaft in the direction of rotation of the motor. To
speed up filling of the sealing chamber, fill the sealing chamber of the pump via the vent hole1,
until pumped liquid is emitted.
5. Retighten the screw plug of the pressure-side vent hole3.
6. Retighten the screw plug of the vent hole1.
10.2.3 Checking the direction of rotation
The direction of rotation is indicated by an arrow on the pump flange. The direction of rotation of the
motor specifies the direction of rotation of the pump. The fan impeller of the motor must rotate in the
same direction in which the arrow for the direction of rotation on the pump flange points.
Notice Standard direction of rotation: clockwise (viewed from the motor)
Personnel qualification: o Fitter
