Submersible dirty water pump UNILIFT AP 12.40.04.3 0.4kW 3x400V 10m 96011024

Dirty water pump – a reliable solution for demanding applications

The Grundfos UNILIFT AP 12.40.04.3 submersible pump is an efficient device designed for draining dirty water, sludge and sewage from various types of excavations, basements, canals and other places where there is a risk of flooding. Made of high-quality stainless steel, it guarantees durability and corrosion resistance even in harsh working conditions. Three-phase power supply (3x400V) ensures stable operation and high energy efficiency.

Design and parameters – the key to efficient operation

This pump is distinguished by a solid construction and well-thought-out solutions. The housing made of stainless steel 304 (1.4301) and the impeller made of stainless steel 304 (1.4301) ensure long-term operation even in an aggressive environment. Thanks to the maximum head of 10 meters and a flow rate of up to 14 m³/h, the pump is able to effectively cope with draining water from deep excavations or flooded rooms. The length of the power cable (10m) provides convenience during installation and use, and the IP68 protection class guarantees tightness and safety of operation when submerged to a depth of 7 meters.

Advantages for professionals and end users

• Durability and reliability: Made of high-quality stainless steel, ensuring a long service life of the pump, minimizing costs associated with repairs and replacements.
• Efficiency: Engine power of 0.7 kW translates into effective drainage of dirty water, shortening the time of work related to dewatering.
• Versatility: The pump works perfectly both in professional applications (construction, earthworks) and in households (draining water from basements, tanks).
• Safety: Insulation class F and protection class IP68 ensure safe operation in difficult environmental conditions.
• Resistance to contamination: The maximum size of solids at 12 mm allows pumping water containing small impurities without the risk of damage to the pump.
• Possibility of continuous operation: Nominal duty type S3 allows long-term operation of the pump without fear of overheating or failure.
• Ready to use immediately after connection: The pump is adapted to be connected via a cable - it does not require any additional preparatory work before starting.
• Operation in a dry environment: The possibility of starting the pump without immersion (for dry configuration: true) increases the range of its applications.

The UNILIFT AP 12.40.04.3 pump is an investment in a reliable and efficient tool that will perform well in many demanding tasks related to draining dirty water and sewage. Its solid construction and high quality of workmanship guarantee long-term operation and satisfaction for both professionals and home users.
