The SL range has been developed to optimise performance in your system, minimising known risk factors and reducing maintenance requirements. Remarkably durable, the SL range offers long lasting, service-friendly submersible wastewater pumping.
The highest standards of motor efficiency ensure substantial energy and cost savings. Motors are based on high-efficiency components, improving motor efficiency and prolonging pump life.
The pumps are available with SuperVortex impellers (SLV) for applications with required low operating hours, dry matter content up to 5 %, and a spherical free passage up to 100 mm, or with the S-tube impeller (SL1) for applications with required high operating hours, dry matter content up to 3 %, and a spherical free passage up to 100 mm.
The S-tube impeller is the only impeller on the market designed to cope with the challenges of modern wastewater with varying dry matter content. The simple and robust design of the S-tube impeller offers world class hydraulic efficiency without compromising free passage.
The SL pump is designed for the transfer of drainage and surface water, domestic, municipal and industrial wastewater, and process water.
The SL pump is also available in an explosion-proof (Ex) version. SL pumps are available in variants with a stainless steel impeller for aggressive environments.
