The SL range 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 SL provide technologically advanced pumps for wastewater pumping.
Designed for demanding situations, the Grundfos SL 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.
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 range is 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.

The S-tube impeller offers world class hydraulic efficiency without compromising free passage.
Intelligent technology adapts with precision to deliver optimal performance, energy efficiency, and reliability.
Functionality that makes installation, operation and maintenance easier and more user-friendly.
Wet balancing cuts vibration up to 70% ...
Closed impellers have been around for decades, but until now, they have had issues with vibration, clogging and inefficiency in wastewater applications.
Why the time is now for the S-tube® ...
The Grundfos S-tube® impeller is designed to transport an increased volume and diversity of wastewater over longer distances while using less energy and transportation fluid.
Understanding IE3 standards and ...
Today no legislation enables a wastewater pump with an integrated motor to be IE3 compliant – and we want our customers to know that.
Lifecycle costs for wastewater pumps
Lifecycle cost calculations in wastewater installations can realise huge savings over time for the wastewater company. The lifecycle costs summarise the total cost of a wastewater installation – and in this regard the pump system plays a major role.
Reliability and lower LCC
A reliable pump operation is a must when dealing with wastewater and this reliability must remain at the same level year-by-year.
Improve wastewater plant reliability ...
Modern wastewater management demands an intelligent, proactive approach. Grundfos iSOLUTIONS goes beyond the pumps alone to deliver intelligent controls and communication capabilities that help the system adapt automatically to dynamic conditions.
