Submersible dirty water pump – a reliable solution for home and professionals

This efficient Grundfos Unilift AP35B.50.08.A1 submersible pump is designed for pumping dirty, contaminated water and sewage. The solid construction and high quality of workmanship guarantee long-lasting and trouble-free operation both in domestic and professional applications – for example, on construction sites, in farms or during emergencies.

Design and application

The pump is vertical, single-stage and made of chrome-nickel steel, which ensures corrosion and mechanical damage resistance. Blocked with a single-phase motor, it is ready to use immediately after connection. Equipped with a 10-meter power cable with a plug and a float that automatically turns the pump on and off depending on the water level. A VORTEX impeller allows for free flow of contaminants up to 35 mm in diameter, minimizing the risk of clogging. It can be installed as a free-standing pump or with an automatic coupling.
