Submersible dirty water pump UNILIFT AP 50B.50.08.1 0.74kW 1x230V 10m 96004587

Submersible dirty water pump – reliability in every application

This efficient UNILIFT AP 50B.50.08.1 submersible pump from Grundfos is a robust solution for draining contaminated water, both in domestic and professional applications. Made of stainless steel, it guarantees long-lasting and trouble-free operation even in difficult conditions. Its design allows for effective pumping of water with solid particles up to 50 mm in diameter, making it ideal for emptying flooded basements, drainage wells, tanks and other places where contaminated water occurs.

Design and application

The pump is designed for vertical operation and is ready to use immediately after connection – it is equipped with a 10-meter power cable with a plug. Made of high-quality stainless steel (motor housing made of steel 316 and pump body made of steel 304) provides corrosion resistance and durability. The VORTEX impeller allows for smooth flow of contaminants, minimizing the risk of clogging. This makes the pump perfect for pumping surface water, groundwater and industrial and domestic wastewater (without sewage). The double shaft seal system with oil chamber additionally protects the motor from failure and extends the life of the device.

Performance and operating parameters

The UNILIFT AP 50B.50.08.1 pump offers a motor output of 740 W and a nominal flow rate of up to 12.11 m³/h, reaching a maximum efficiency of 24 m³/h. It provides a head of up to 11 meters, allowing for effective pumping of water even from deep places. The motor speed is 2790 revolutions per minute, and the insulation class F guarantees safe and reliable operation. The pump's rated current is 5.37 A at 230 V and a frequency of 50 Hz. The IP68 degree of protection ensures complete sealing and the possibility of continuous operation when submerged to a depth of 7 meters. The pump weighs 11.5 kg and has a diameter of 210 mm, making it easy to transport and install.
