Subsurface sewage collection pits and large-scale drainage stations require the robust hydraulic performance of the SE2.110.250.185.4.52L.N.51D.A.T Submersible Wastewater Pump. This assembly is built for intensive duty in municipal networks, handling contaminated fluids within a liquid temperature range of 10°C to 40°C. Maintaining consistent throughput is critical for treatment plants and lift stations prone to significant fluid ingress. It provides a durable solution for civil infrastructure where performance must remain stable across varying environmental demands and high flow rates.
Performance is delivered by an 18.5 kW four-pole motor on a 415v three-phase supply, producing a rated current of 37 Amps. The pump generates a maximum flow of 14160 L/min and reaches a maximum head of approximately 11.7 m for efficient evacuation of municipal wastewater and high-volume sewage. Starting is managed via a star-delta method to protect the motor assembly, while the 1479 rpm rated speed ensures torque stability. Power is distributed through a 15-metre S1BN8-F power cable to facilitate deployment in deep subsurface collection pits and civil complexes.
Internal centrifugal pathways utilize a cast iron DUAL S-TUBE impeller designed to facilitate the passage of solids up to 110 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 particles to move freely through the housing, the unit ensures consistent volumetric throughput during prolonged operation. The DUAL S-TUBE impeller is specifically engineered for reliable wastewater transfer where durability is a priority for the infrastructure maintenance.
Mechanical integrity is reinforced by a heavy-duty cast iron body with an IP68 enclosure rating for immersion up to 20 m across an ambient temperature range of -20 to 40°C. Motor protection is provided by a double mechanical shaft seal featuring silicon carbide faces in an oil bath, ensuring the motor remains shielded from liquid ingress. This model includes internal moisture sensors and thermistors for real-time monitoring of the Class H insulated motor assembly. Standard DN 250 inlet and DN 250 outlet connections ensure high-capacity pipework compatibility.
