Grundfos waste water pump waste water pump SLV with Vortex impeller



SLV waste water pump with Vortex impeller

A waste water pump or submersible pump offers a solution in situations where waste water does not pass through the normal
sewerage can be disposed of. Diederen Afwateringstechniek supplies a waste water pump, submersible pump, waste water pump or sewer pump from the Grundfos brand. The high-quality waste water pump or submersible pump from Grundfos can be found everywhere where waste water must be pumped, cleaned and removed.

The SE and SL waste water pumps programs offer the highest total efficiency that is available in the market. Innovative Grundfos technologies combine intelligence, motors, hydration and functionality for the challenges of modern wastewater, maximizing the hydraulic, electrical and mechanical efficiency of your pumps.

The pumps are available with SuperVortex impellers (SEV) for applications with a low number of operating hours, dry matter content higher than 5% and a spherical free passage up to max. 100 mm, or with the S- tube impeller for applications with a high number of operating hours, a dry matter content of up to 3% and a spherical free passage of up to 160 mm.

The S- tube impeller is the only impeller on the market that is designed for the challenges of modern wastewater with a variable dry matter content. The simple and robust design of the S- tube impeller offers world-class efficiency without compromising on free passage.

The SE and SL programs are built for years of trouble-free operation and can be installed wet or dry without engine cooling. In addition, they are extremely reliable and easy to maintain.



The Grundfos SEV and SL pump programs are designed for the processing of waste water, process water and unfiltered sewage water in heavy-duty municipal, commercial and industrial applications. They can be permanently installed using an automatic connecting guide rail system or a fixed pipe connection; the pumps are also suitable for freestanding installation, or as portable company pumps.
