More about this product

Full Description

Non-self-priming, single-stage, centrifugal pump designed for handling wastewater, process water and unscreened raw sewage. The pump is designed for intermittent and continous operations in submerged installation. The revolutionary S-tube® impeller provides free spherical passage of solids up to 100 mm and is suitable for wastewater with a dry matter content of up to 3 %. A unique stainless-steel clamp assembling system enables quick and easy disassembly of the pump from the motor unit for service and inspection. No special tools are required. Pipework connection is via a DIN flange.

Additional Information

The S-tube offers greater hydraulic efficiency than any other type of wastewater impeller, without compromising free passage.

This results in the lowest life cycle cost, trouble free operation and best-in-class non-clogging capabilities.

When you package this innovative, elegant and simple impeller design in the outstanding SE and SL ranges of submersible wastewater pumps and add IE3 motor components and super intelligent controls, we truly believe we are looking at the ultimate in wastewater pumping technology.

With the S-tube, Grundfos sets new standards for wastewater hydraulic design.

The S-tube resolves the challenges with sealing, vibration, abrasive wear and clogging that owners of wastewater pumping stations have lived with for way too long.
