9 Possible connection positions
Counterclockwise rotation of the rotor and motor Clockwise rotation of the rotor and motor
Unless otherwise ordered, the pump is delivered in position B
10 Changing the connection position
Remove the screws on the bearing block. Turn the housing by an angle of 45° to the left or right.
Tighten the screws again. (
45 Nm )
However, take care that due to the corresponding arrangement of the pressure line in the pump, a certain
residual amount remains. By this measure you make it easier for the pump to draw in highly viscous products.
However, in the case of horizontally lying pressure connection you must absolutely take care that the pressure
line is run so that the pump is always covered with residual liquid. In this way total dry running is avoided.
11 Changing the direction of rotation
The suction or the pressure side changes on
changing the direction of rotation of the drive.
Then the
Scraper and the Scraper gate guide
must absolutely be turned, since otherwise the
pump cannot bring its full output. If the direction of
rotation is changed, the rotation direction arrows
must be turned correspondingly. Further the
suction or pressure connection must be marked.
The set direction of rotation is stated by an arrow.
The pump can run against the set direction only
for a short time. It cannot build up more than 2
bar pressure if the direction of rotation is wrong.
Let the change of direction of rotation on the drive be made only be trained skilled
personnel. The motor must be protected against unintentional switching on!
When the connection position is changed, the motor must be protected against
unintentional switching on!!
If the Rotor turns counter clockwise If the Rotor turns clockwise
