Pleuger booster pumps are single-stage or multi-stage centrifugal pumps coupled with water-filled motors. The unit is arranged in a booster shroud and are integrated horizontally or vertically into the system to increase the pressure. Booster pump units are available in standard configuration or engineered to order for specific requirements.
