Motor
Centrifugal hydraulics with different impeller shapes, horizontal flange connection on the
pressure side, inspection cover as well as neck and impeller wear rings.
The hydraulics are not self-priming, in other words, the fluid must flow in either automati-
cally or with supply pressure.
Impeller shapes
The individual impeller shapes depend on the size of the hydraulics and not every impeller
shape is available for every hydraulic system. The following is an overview of the different
impeller shapes:
▪ Vortex impeller
▪ Single-channel impeller
▪ Two-channel impeller
▪ Three-channel impeller
▪ Four-channel impeller
▪ SOLID impeller, closed or semi-open
Inspection cover (depending on the hydraulics)
Additional opening on the hydraulics housing. This opening is used to remove clogging in
the hydraulics.
Neck and impeller wear rings (depending on the hydraulics)
The suction port and impeller are subjected to the most stress when pumping. In the case of
channel impellers, the gap between the impeller and the suction port is an important factor
for a constant efficiency. The larger the gap between the impeller and the suction port, the
higher the losses in the delivery rate. The efficiency decreases and the danger of clogging
increases. In order to ensure long and efficient operation of the hydraulics, an impeller wear
ring and/or neck ring is installed depending on the impeller and the hydraulics.
▪ Impeller wear ring
The impeller wear ring is attached to the channel impellers and protects the incoming flow
edge of the impeller.
