Internal fluid pathways and hydraulic configuration in the SE1.110.200.200.4.52M.N.51D.A.T Submersible Wastewater Pump are engineered for high-capacity transfer in municipal networks. This cast iron unit provides a professional solution for lift stations and treatment plants where the liquid temperature range is 10°C to 40°C. Maintaining steady flow behavior during continuous duty is necessary for facility protection and long-term infrastructure maintenance. It is intended for submerged or dry installation in aggressive environments where consistent liquid movement is a critical operational priority.
Performance is driven by a 20 kW four-pole motor on a 415v three-phase supply, producing a rated current of 39 Amps. The pump generates a maximum flow of 8340 L/min and reaches a maximum head of 21 m for efficient evacuation of municipal wastewater and high-volume sewage. The unit utilizes a star-delta starting method to manage peak electrical loads and operates at a rated speed of 1478 rpm. Power is distributed through a 15-metre power cable to facilitate installation in deep collection pits and subsurface infrastructure across large-scale municipal complexes.
Internal hydraulics utilize an S-TUBE impeller designed to facilitate the passage of solids up to 110 mm without internal contact. This specialized hydraulic configuration offers high efficiency and significantly reduces the risk of blockages during intensive sewage pumping cycles. By enabling the free passage of suspended solids through the housing, the unit maintains volumetric throughput throughout its service life. This impeller setup is specifically engineered for high-capacity liquid handling where durability is critical for system reliability and maintenance across an ambient temperature range of -20°C to 40°C.
Mechanical construction features a heavy-duty cast iron body and motor shell with an IP68 protection rating for depths up to 20 m. Long-term reliability is supported by a double mechanical shaft seal featuring silicon carbide faces in an oil bath to shield the motor from liquid ingress. Integrated thermistors and moisture sensors are included to facilitate proactive monitoring of the Class H insulated motor assembly. This pump features a 364 kg net weight and includes standardized DN 200 inlet and DN 200 outlet connections for high-capacity pipework integration.
Features
