Product Overview
Effluent transfer in large-scale wastewater treatment facilities and municipal drainage stations depends on the performance of the SE1.95.150.200.4.52H.N.51D.A.T Submersible Wastewater Pump. This cast iron unit provides a durable solution for lift stations and treatment plants where the liquid temperature range is 10°C to 40°C. Maintaining hydraulic throughput during continuous duty is essential for facility protection and long-term infrastructure maintenance. It is intended for submerged or dry installation in environments where reliable sewage collection is necessary for civil maintenance.
This model operates on a 415v three-phase supply and utilizes a 20 kW motor with a rated current of 39 Amps. The system achieves a maximum flow of 4986 L/min and produces a maximum head of 27 m for high-volume discharge in collection pits. Starting is managed via a star-delta method to protect the electrical assembly, while the 1478 rpm rated speed ensures torque stability during intensive duty cycles. A 15-metre power cable is provided for installation in deep collection pits and large complexes across an ambient temperature range of -20°C to 40°C.
Internal hydraulics are built around an S-TUBE impeller designed to facilitate the passage of solids up to 95 mm without internal contact. This specialized hydraulic configuration offers high efficiency and significantly reduces the risk of blockages during intensive sewage pumping duties. 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 municipal and industrial wastewater transfer where clog resistance is a critical operational priority for treatment plants.
The 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 anchored 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 standardized DN 150 inlet and DN 150 outlet connections for seamless integration into high-capacity municipal pipework and drainage systems.
