Designed for massive municipal wastewater collection, the SE2.125.300.180.6.52E.N.51D.A.T Submersible Wastewater Pump delivers reliable performance in the most demanding drainage applications. This assembly is built for intensive duty in large complexes, handling contaminated fluids within a liquid temperature range of 10°C to 40°C. Maintaining consistent throughput is critical for drainage stations and lift stations prone to massive fluid ingress. This unit addresses the need for durable liquid movement in subsurface collection pits where performance must remain stable across an ambient temperature range of -20 to 40°C.
Performance is delivered by an 18 kW six-pole motor on a 415v three-phase supply, producing a rated current of 37 Amps. The pump generates a maximum flow of 19380 L/min and reaches a maximum head of approximately 10.7 m for efficient evacuation of municipal wastewater and high-volume effluent. The unit utilizes a star-delta starting method to manage peak electrical loads and operates at a rated speed of 971 rpm. Power is distributed through a 15-metre S1BN8-F power cable to facilitate installation in deep collection pits and large-scale infrastructure complexes across municipal networks.
The centrifugal hydraulic system utilizes a high-efficiency DUAL S-TUBE impeller to manage solids in suspension up to 125 mm. This configuration provides superior clog resistance and ensures reliable wastewater transfer without the risk of internal blockages or contact. By utilizing a DUAL S-TUBE design, the pump maintains consistent efficiency over thousands of service hours in aggressive environments. This hydraulic setup is specifically intended for municipal wastewater transfer where maintaining flow without interruption is a critical priority for system reliability and facility maintenance.
Mechanical integrity is reinforced by a cast iron pump body with an IP68 enclosure rating for immersion up to 20 m deep. Motor protection is provided by a double mechanical shaft seal featuring silicon carbide faces in an oil bath, ensuring the motor remains protected from ingress. This model includes internal moisture sensors and thermistors for real-time monitoring of the Class H insulated motor assembly. Standard DN 300 connections are used for both inlet and outlet to ensure compatibility with standardized municipal wastewater and high-capacity drainage infrastructure.
