Grundfos SL1 Submersible Wastewater Pump

Pump submersible pump Grundfos SL1 is a submersible wastewater pump in the Grundfos range pump Grundfos with strong solids-cutting and solids-handling capability, allowing solids passage up to the pump discharge diameter for demanding wastewater applications.

The Grundfos SL1 submersible wastewater pump is equipped with a high-efficiency Grundfos blueflux® motor, significantly reducing energy consumption over the pump's service life. Grundfos blueflux® motor technology exceeds current market standards and meets stringent motor-efficiency requirements.

The Grundfos SL1 submersible pump is engineered to reduce service and maintenance costs over its operating life. The motor cable entry is made of stainless steel and designed to prevent moisture ingress during operation.

The Grundfos SL1 submersible pump is equipped with a moisture sensor that sends a signal to the control panel, enabling early detection and corrective action before the motor is damaged. A thermal sensor also protects the pump from overload if solids cause a blockage, supporting reliable long-term operation.

A key feature of the SL1 submersible pump is its impeller design, engineered to handle and pass solids efficiently, supporting wastewater pumping in applications with high debris loads.
