SE-SL

Overview

Overview

The SE and SL ranges of wastewater pumps provide the highest total efficiency on the market. Innovative technologies from Grundfos bring together intelligence, motors, hydraulics and functionality to meet the challenges of modern wastewater, maximizing the hydraulic, electrical and mechanical efficiency of your pumps.


Bringing it all together

The renewed and expanded range of Grundfos SL and SE wastewater pumps continue the tried and tested SL and SE story, providing technologically advanced pumps for wastewater pumping. 

Designed for demanding situations, the Grundfos SL and SE pumps show our commitment and approach to innovative technologies for the wastewater market, raising the bar and setting new standards for wastewater pump systems and solutions.

Optimum wire-to-water efficiency is ensured by the technologies that we put into our pumps and pump systems. The highest motor efficiency, the adaptive intelligence through world-class controls, the user-friendly design and functionality and the S-tube impeller ensure the best total efficiency, the lowest life cycle costs and trouble-free operation for your wastewater pump systems and solutions.

The SL range is for submerged installation and the SE range for dry and submerged installation.


State-of-the-art hydraulics

The very nature of wastewater is challenging, with dry solids content varying over time. Similarly, water use has not remained static either. However, the demands on the wastewater pump remain the same: In addition to being as efficient as possible, it must also pump media containing large solids, rags and fibers without clogging the pump.

The SL and SE ranges are available with the S-tube impeller – the only impeller on the market designed to take on these challenges. The simple and robust design of the S-tube impeller meets the requirements of today’s wastewater with varying solids content, offering world-class hydraulic efficiency without compromising free passage.
