AWTOOLS Waste Water Pump with Grinder 850W - Submersible Sewage Pump, 15000 L/h, 10 m Head, Stainless Steel Grinder, Automatic Float Switch, 10 m Cable, IPX8

In flooded basements, septic tanks, or construction sites, the AWTOOLS 400460 waste water pump with grinder is the workhorse that clears the mess. Its 850 W oil-cooled induction motor drives an integrated stainless steel grinder, shredding solids and fibrous material to prevent clogs, while the automatic float switch starts and stops the pump as water levels rise and fall. With a maximum flow rate of 15,000 litres per hour and a 10-metre head, it moves large volumes quickly, even against gravity.

Why choose it

This pump is built for the dirtiest jobs. The stainless steel grinder macerates solids, so you can pump sewage, sludge, and dirty water without fear of blockages. The cast iron and stainless steel construction resists corrosion and wear, while the IPX8 rating means it can be fully submerged without damage. The automatic float switch prevents dry running, extending the motor's life. The 10-metre cable gives you flexibility in deep sumps or distant basins.

Ideal use cases

• Draining flooded basements, cellars, and garages
• Emptying septic tanks, cesspits, and sewage pits
• Removing dirty water from construction sites and excavations
• Transferring water with solids in agricultural or industrial settings
• Emergency flood response where debris is present

Good to know

The pump comes with a hose connection and multi-size adapters, making it compatible with common hose diameters. It handles non-grindable particles up to 30 mm, but the grinder will reduce larger organic solids to prevent clogging. The oil-cooled motor ensures reliable continuous operation, and the automatic float switch means you can set it and forget it. For best results, ensure the pump is placed on a stable surface and the discharge hose is free of kinks.
