Submersible dirty water pump UNILIFT AP 50B50.15.3 1.5 kW 3x400V 10 m 96468196

Dirty water pump – reliability and efficiency in one

The UNILIFT AP 50B50.15.3 submersible pump is a solid solution for draining contaminated water, sewage and surface water. Made of stainless steel, it guarantees long-lasting and trouble-free operation even in difficult conditions. Designed for use in both households and industry or construction. Its construction allows for efficient pumping of liquids with solid particles up to 50 mm in diameter, making it ideal for removing contaminants from flooded basements, excavations or tanks.

Design and application

The UNILIFT AP 50B50.15.3 pump is a vertical, single-stage device with a three-phase motor with a power of 1.5 kW. Made of high-quality stainless steel (body) and stainless steel 316 (motor housing), it provides resistance to corrosion and mechanical damage. Thanks to this, it can operate in an aggressive environment for a long time without loss of performance. Equipped with a 10-meter power cable, it is ready for immediate use after connecting to a 400V power source. The 2 inch (50 mm) discharge port allows for easy connection to pipes of standard dimensions.

Performance and reliability

This pump offers a maximum performance of 31 m³/h and a maximum head of 17 meters. The nominal efficiency (BEP) is 16.5 m³/h at a head of 107.06 kPa. The motor operates in S3 mode, which means it is designed for intermittent or cyclic operation. Insulation class F and maintenance-free, permanently lubricated ball bearings ensure long life and minimize the need for maintenance. Protection class IP68 guarantees complete sealing and the possibility of immersing the pump to a depth of 7 meters, making it ideal for working in flooded areas. The VORTEX impeller allows for the free flow of solid particles up to 50 mm in diameter, minimizing the risk of pump clogging and ensuring continuous operation.
