Pleuger Bottom intake pump units are single or multi-stage centrifugal pumps, which are 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 to reduce the water line to a very low level. Bottom intake pump units are designed for vertical or slightly inclined installation. The pump units are available in standard configuration or according to special customer requirements.
