Pleuger Bottom intake pump units are single or multi-stage centrifugal pumps, coupled with water-filled motors. The motor is arranged above the pump in a special bypass shroud and the pump intake is located in the lower part of the unit. The design allows reduction of the water line to a very low level. Bottom intake pump units are designed for vertical or inclined installation and are available in standard configuration or engineered to order for specific requirements.
