Submersible Dirty Water Pump 400W STHOR 79781

Flooded basements, construction pits, or ponds with debris-laden water demand a pump that won't choke on solids.

Its rugged plastic housing and IPX8 waterproof rating ensure reliable operation fully submerged down to 5 metres, while the integrated float switch automates the process to prevent dry running.
