Submersible dirty water/dewatering pump UNILIFT KP 250AV1 0.5kW 1x230V, 10 m cable 012H1900

Dirty water and drainage pump – a reliable solution for home and professionals

This efficient Grundfos Unilift KP 250AV1 submersible pump is a versatile device designed for removing dirty, contaminated water and for drainage. It will be useful both in households during basement or garden flooding, as well as on construction sites, in agriculture or in industry. Its solid construction and high efficiency guarantee long-lasting and trouble-free operation.

Design and application

The Unilift KP 250AV1 pump is designed to operate in difficult conditions. Made of high-quality stainless steel (body made of stainless steel 304, impeller also made of stainless steel 304), it provides resistance to corrosion and mechanical damage. Thanks to the ability to pump water from a level of only 3 mm (after removing the grid), it is ideal for emptying tanks, excavations or basements with a small amount of water. The use of a check valve in the pump prevents water from flowing back after the device is switched off, which is particularly important in permanent installations. Equipped with a 10-meter cable with a plug, it facilitates connection and use.

Advantages and key features

• Efficiency: The pump offers a nominal flow rate of 5.81 m³/h, and the maximum flow rate reaches 11.2 m³/h, allowing for quick removal of water even from large areas.
• Lift height: The maximum lift height is 7.5 meters, allowing for pumping water to a significant height or to further collection points.
• Corrosion resistance: The body and impeller made of stainless steel provide long-lasting protection against the action of aggressive substances contained in dirty water.
• Dry running protection: Dry running protection protects the pump from damage in the event of accidental starting without immersion in water – this is particularly important for occasional use.
• Versatility: The possibility of use in both permanent and temporary installations makes the pump a flexible solution for various needs.
• Solid construction: The motor housing made of stainless steel 316 (1.4401) provides additional durability and corrosion resistance.
• Protection class IP68: Guarantees full protection against immersion and dust, allowing safe operation in difficult environmental conditions.
• Maximum solid particle size: The pump can handle particles up to 10 mm in diameter, allowing it to pump water with small impurities.
• Nominal duty type S3: This means that the pump is designed for intermittent operation with cyclic load – an ideal solution for applications requiring periodic operation of the device.
