Grundfos SE1.110.200.130.4.52M.N.51D.A.T Cast Iron Sewage Pump for Effluent Handling with S-Tube Impeller

Internal fluid pathways in the SE1.110.200.130.4.52M.N.51D.A.T are specifically configured for high-velocity transfer of contaminated liquids with significant solids concentrations. This hydraulic setup utilizes an S-TUBE impeller to facilitate the passage of particles up to 110 mm without inducing internal blockages. By prioritizing smooth centrifugal flow, the pump maintains performance stability during high-volume discharge cycles in municipal networks and treatment plants. It is intended for wastewater transfer duties where a liquid temperature range of 10°C to 40°C and consistent flow behavior are required for infrastructure maintenance.

Technical capacity is driven by a 13 kW four-pole motor operating on a 415v three-phase supply with a rated current of 25 Amps. This configuration generates a maximum flow of 6180 L/min and achieves a maximum head of 16 m to satisfy requirements in large collection complexes. The motor operates at 1483 rpm and utilizes a star-delta starting method to manage peak electrical loads during initial activation. Power is distributed through a 15-metre S1BN8-F power cable to facilitate deployment in deep subsurface wastewater handling pits and industrial treatment infrastructure across municipal networks.

The centrifugal hydraulic system provides superior clog resistance and ensures reliable wastewater transfer, reducing the risk of downtime in aggressive environments. By enabling the free passage of suspended solids through the housing, the unit maintains volumetric efficiency throughout its service life. This S-TUBE impeller configuration is engineered for durability, maintaining throughput throughout thousands of operating hours in aggressive fluids and an ambient temperature range of -20°C to 40°C. This setup is specifically intended for grey water and sewage handling where system reliability is critical for maintenance.

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. Integrated thermistors and moisture sensors are included to facilitate proactive monitoring of the Class H insulated motor assembly. This pump features a 355 kg net weight and includes standardized DN 200 inlet and DN 200 outlet connections for high-capacity integration into standardized pipework.
