The volute casing is split in two halves along a vertical plane.
Since the suction and discharge nozzles are provided in the rear half of the casing, the rotating element can be taken out by removing only the front half casing without disturbing the rest of the pump.
The pumping element is made up of a top cover, a pump shaft, an impeller, a bearing bush and a sealing arrangement around the shaft.
The sealing arrangement may be a packed gland or a mechanical seal and the bearing lubrication system will vary according to the type of seal.
Replaceable wear rings are fitted in the casing around the top and bottom faces of the impeller.
The motor support bracket has two large apertures to provide access to the pumping element, and a coupling spacer is fitted between the motor and pump shaft to enable the removal of the pumping element without disturbing the motor or vice versa
