Grundfos SE.100.130.4.52H.N.51D.A.T Cast Iron 4-Pole Sewage Pump for Effluent with Open S-Tube Impeller

Operational efficiency in municipal wastewater collection requires robust subsurface assets capable of processing high ingress volumes in dry or submerged installations. The SE.100.130.4.52H.N.51D.A.T ensures circulation stability for effluent management where fluid temperatures reach 40 degrees Celsius. Maintaining structural integrity during continuous duty is necessary for drainage stations and subsurface collection pits. This unit is intended for wastewater transfer and municipal networks where reliable wastewater transfer is required.

Hydraulic capacity is driven by a 13 kW four-pole motor operating on a 415v three-phase supply with a rated current of 26 Amps. This assembly generates a maximum flow of 6960 L/Min and reaches a maximum head of 24.7 m. The motor utilizes a star-delta starting method to manage peak electrical loads and maintain torque stability during initial activation cycles. Operating at a rated speed of 1483 rpm, the unit ensures consistent pressure behavior for high-volume wastewater management.

Internal centrifugal design utilizes a high-efficiency Open S-Tube impeller to facilitate the passage of solids in suspension without internal contact. This configuration handles particles through the housing, preventing the internal clogging that compromises volumetric efficiency over long-term service. By utilizing the Open S-Tube principle, the design reduces internal wear and vibration for the rotating assembly during high-volume discharge. The Open S-Tube setup is intended for high-volume wastewater transfer in municipal and industrial collection 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 featuring silicon carbide faces in an oil bath for motor insulation. This model includes integrated thermistors and moisture sensors to facilitate proactive monitoring of the Class H insulation motor assembly. The architectural casting features a 362 kg net weight and DN 150 inlet with DN 100 outlet connections for standardized infrastructure.
