These pumps feature single or multi-stage centrifugal units directly coupled to a water-filled submersible electric motor. The motor is mounted in an inverted position with a cooling shroud that uses the discharged fluid for efficient cooling, while a mechanical seal prevents ingress of water into the motor.

The design of the suction at the lowest part of the set allows maximum submergence, ensuring optimal suction conditions even at low water levels and efficient utilization of water reserves. Polder Submersible Pumps can deliver heads up to 200 meters with flow rates up to 1000 m³/hr and operate at speeds of 1450 or 2900 RPM. These pumps are ideal for applications including dewatering, sump drainage, clear water pumping, raw water transfer, intake wells, irrigation schemes, and handling of corrosive liquids. Built for reliability and longevity, SB Polder Pumps provide robust performance with low maintenance in demanding environments.
