How do you reverse the rotation of a pump?
The direction of rotation of the pump is always indicated by an arrow on the label located on the pump housing.
To reverse the rotation of the pump, carefully disassemble the pump. Then remove the toothed wheels and install as shown in Figure 2. During assembly, turn the gear wheels and similarly the front cover. It is important that the bushings are mounted as before. Tighten the bolts using a torque wrench.
