Flender GmbH 2NER GROUP CO.,LIMITED Germany sogears HB series gearbox 8/4 Flender MD 2.1 2Special mounting positions Water screw (pump) gear units Overview Water screws are used to lift water. The screw operates according to the "Archimedean principle". The slow speed shaft is tilted downwards between 3 and 3. Water screw pumps are also suitable for pumping heavily con- taminated liquids, even those containing small solid particles. The delivery head is normally only few meters and the flow rate relatively high. The output shaft of the gear unit, whose mounting position cor- responds to the inclination angle of the screw, does not absorb any additional loads and transmits the torque to the screw shaft by means of flexible coupling. Flender gear units are specially designed to operate in these conditions. Here, gear unit with adapted oil level, corre- sponding shaft seal, an oil drain, and special breather is required. Each gear unit is fitted with backstop to prevent the screw from accelerating backwards by the water that is forced back when the motor is switched off.
