Closed coupled monobloc pumps with end suction
These are of two types – canned and magnetic drive pumps:
1. Canned pumps: In the construction of this second type of sealless pump,
the rotor comprises of an impeller, shaft, and the rotor of the motor. These
are housed within the pump casing and a containment shell (Figure 1.23).
The hazardous or the toxic liquid is confined within this shell and casing.

The rotating flux generated by the stator passes through the containment shell and
drives the rotor and the impeller.
2. Magnetic drive pumps: In magnetic drive pumps, the roto ...
