Product Overview
Developed for large-scale municipal infrastructure, the Grundfos SL.56M.410.4.50D.200 is intended for permanent submerged installation in commercial wastewater networks. This cast iron pump holds CE EN12050-1 certification with ROHS and WEEE approvals. It is suitable for handling raw effluents and untreated wastewater containing solids at temperatures between 0°C and 40°C.
The pump incorporates a 41 kW 4-pole motor running at 1485 rpm on a 3 x 415 V supply with a rated current of 78 Amps. It achieves a maximum head up to 37 m and a maximum flow up to 17340 L/min. The motor is rated for continuous S1 duty and utilizes the surrounding pumped liquid for thermal cooling.
The hydraulic design uses an Open S-tube impeller with a 351 mm actual diameter for managing untreated wastewater. The nominal duty head is 20.03 m. The pump incorporates dual DN 200 connections with DIN flanges, supporting high-volume wastewater transfer while reducing the risk of clogging in commercial collection systems.
Construction features an EN-GJL-250 cast iron pump housing and motor casing with double mechanical shaft seals. Protection is provided by integrated PTO sensors for motor protection and monitoring. The unit is supplied with a 10-metre S1BC4N8-F EMC power cable and an IP68 enclosure suitable for installation depths up to 30 metres.
