Grundfos SE.100.265.2.52S.N.51D.A.T Cast Iron 2-Pole Sewage Pump for Industrial Wastewater with Open S-Tube Impeller

High-head wastewater discharge for industrial complexes is facilitated by the heavy-duty architectural build of the Grundfos SE.100.265.2.52S.N.51D.A.T. This submersible unit addresses requirements for the removal of contaminated liquids in collection pits where reliable solids passage is required. The system maintains stable performance in permanent submerged environments with liquid temperatures up to 40 degrees Celsius. Maintaining operational flow behavior in deep subsurface pits is essential for industrial transfer duties.

Hydraulic performance is provided by a 26.5 kW motor operating on a 415v three-phase supply with a rated current of 53 Amps. This assembly generates a maximum flow of 5466 L/Min and achieves a maximum head of 60.5 m. The motor operates at 2967 rpm, ensuring consistent torque and hydraulic stability throughout the service cycle in drainage stations. Electrical distribution is managed via a 15-metre power cable to facilitate deployment in subsurface wastewater infrastructure.

Internal fluid paths utilize an Open S-Tube impeller designed for the centrifugal movement of liquids without internal clogging or contact. This configuration allows for the passage of solids through the housing to maintain volumetric efficiency over thousands of service hours in industrial networks. By utilizing a high-efficiency hydraulic design, the unit minimizes internal wear and vibration for the rotating assembly during high-head discharge. The Open S-Tube setup is intended for high-volume wastewater transfer in industrial and municipal systems.

Mechanical construction features a heavy-duty cast iron body and motor shell with an IP68 protection rating for depths up to 20 m. Longevity is anchored by a double mechanical shaft seal arrangement featuring silicon carbide faces in an oil bath for motor protection. This model includes integrated thermistors and moisture sensors for proactive monitoring and early fault detection in submerged conditions. The casting includes DN 100 connections and Class H insulation for reliable service.
