Grundfos SE2.110.250.130.4.52L.N.51D.A.T Cast Iron Sewage Pump for Sewage Transfer with Dual S-Tube Impeller

Heavy-duty cast iron housing casting and motor shell components ensure the SE2.110.250.130.4.52L.N.51D.A.T Submersible Wastewater Pump maintains performance in aggressive municipal environments. This assembly is built for both dry and submerged installation, processing contaminated fluids within a liquid temperature range of 10°C to 40°C without compromising structural life. Maintaining material integrity is essential for treatment plants and large-scale lift stations prone to debris. It provides a reliable solution for effluent transfer and drainage systems requiring consistent flow.

Capacity is delivered by a 13 kW four-pole motor on a 415v three-phase supply, producing a rated current of 25 Amps. The pump generates a maximum flow of 13620 L/min and reaches a maximum head of approximately 9.5 m for efficient evacuation of municipal effluent and sewage. The unit utilizes a star-delta starting method to manage peak loads and operates at a rated speed of 1483 rpm. Power is distributed through a 15-metre S1BN8-F cable to facilitate installation in deep collection pits and large complexes across an ambient temperature range of -20 to 40°C.

The centrifugal hydraulic system utilizes a DUAL S-TUBE impeller to manage solids in suspension up to 110 mm. This configuration provides superior clog resistance and ensures reliable wastewater transfer without the risk of internal blockages or contact during intensive duty cycles. By utilizing the DUAL S-TUBE design, the pump maintains consistent throughput over its service life in large collection pits. This hydraulic setup is specifically intended for high-capacity liquid handling where maintaining flow without interruption is a critical operational priority.

Reliability is reinforced by a double mechanical shaft seal featuring silicon carbide faces in an oil bath for motor insulation. This model includes internal moisture sensors and thermistors for real-time monitoring of the Class H insulated motor assembly. Standardized DN 250 inlet and DN 250 outlet connections allow for high-capacity integration into municipal wastewater pipework. The IP68 enclosure rating confirms suitability for permanent immersion up to 20 m deep, ensuring protection for both the electrical and mechanical assemblies.
