The cantilever pump is a centrifugal single-stage cast iron pump with a one-way supply of liquid to the impeller. It is, from the point of view of hydraulics, a characteristic type of centrifugal pump, the working member of which is a centrifugal wheel located at the end of the shaft (cantilever) . The supply of torque from the motor shaft to the pump shaft occurs through an elastic coupling. Materials of the main parts of the pumps are gray cast iron, carbon steel. Shaft seal packing
