Impeller

Repair manual
3. Impeller
The impeller (figure 37, point A) is attached to the jet's main shaft. As the
impeller rotates, it generates pressure that is then transformed into the flow
rate.
Figure 37. Impeller
The impeller is attached to the shaft with a mounting flange (figure 37, point
B), which is attached to the impeller with bolts (6 pcs, figure 37, point C). The
torque is transmitted to the shaft using a key. The impeller is held in place by a
sleeve (figure 37, point D) attached to the rear end of the shat with a screw.
The impeller is located in the cone duct, which allows the gap between the
blade and the duct wall to be quite small.
There are rings of various thicknesses (figure 38, point A) on the front side of
the impeller. These define the location of the impeller in the duct and transmit
the thrust from the impeller to the shaft. A plastic insulating ring must always
be present in front of the impeller (figure 38, point B).
