3LS4

In maritime environments, where corrosion resistance and reliability are paramount, stainless steel end suction pumps are essential for a variety of applications, including water treatment, cooling systems, and irrigation. The 3LS4 is a robust centrifugal pump constructed entirely from 316L stainless steel, adhering to the EN733 standard. This monoblock design features a stub shaft, ensuring efficient and reliable operation in challenging marine conditions. The 3LS4 offers an impressive operating range with flow rates up to 240 m³/h for 2-pole models and total heads reaching up to 95 meters, making it suitable for both high-flow and high-head applications. It can handle liquids at temperatures ranging from -10 to 110°C and operates under a maximum working pressure of 10 bar. The pump is available in various outlet sizes from 32 to 80 mm, catering to different system requirements. The mechanical seal, made with SiC/SiC/FPM [Viton] and featuring an anti-rotation device for the stationary seat, ensures long-lasting performance and minimal maintenance. Powered by WEG motors, the 3LS4 is available in both standard (W21) and optional (W22) configurations, offering power ratings from 0.25 to 55 kW. The pump's efficiency meets IE3 standards, and it operates at frequencies of 50 Hz with a protection degree of IP55 and an insulation class of F (B for temperature rise). Ideal for applications such as wastewater treatment, industrial pressure boosting, and irrigation systems, the 3LS4 is a versatile solution that can be customized to meet specific operational needs.
