The cantilever pump is a centrifugal single-stage cast iron pump with a one-way supply of liquid to the impeller. It is, from hydraulic point of view, a characteristic type of centrifugal pump, a working element of which is a centrifugal wheel that is located at the end of a shaft (console) mounted in the bearing of pump housing The input of torque from the motor shaft to the pump shaft occurs via an elastic coupling.
The materials of the main components of the pumps are gray cast iron and carbon steel. The shaft seal is of gland type.
