Axial supports consist of two deep grooved ball bearings that can be lubricated with oil if needed. The spiral chamber is one piece and its supporting bases are cast in one piece. The screw housing is fastened to the chassis by four screws. These pumps are made as detachable assemblies, and the impeller and rotor assembly, in addition to the bearing base, can be separated from the pumping network by the motor for service or repair (without opening the screw housing of the pump from the pipelines). These pumps have a discharge capacity of 5 to 500 cubic meters per hour and provide a height of 5 to 90 meters.
