Submersible dirty water pump UNILIFT AP 35B.50.08.a1 0.71kW 1x230V 5m 96004574

Submersible dirty water pump – reliable drainage

The UNILIFT AP 35B.50.08.a1 submersible pump is a robust solution for removing dirty water from various excavations, basements, canals and other places where water containing impurities appears. Designed to operate in difficult conditions, it provides efficient and reliable operation even with a high level of contamination. Its construction based on durable materials guarantees a long service life and minimizes the risk of failure.

Performance and application

The UNILIFT AP 35B.50.08.a1 pump offers a maximum capacity of 21 m³/h, allowing for quick draining of flooded surfaces. A head of up to 13 meters allows pumping water over significant distances, and a submersion depth of up to 2 meters provides flexibility in various applications. With a pump diameter of 210 mm and the ability to pump media with solid particles up to 35 mm in diameter, the pump copes perfectly with water containing sand, mud, leaves and other contaminants. Equipped with a connection cable with a plug, it facilitates its installation and use.

Construction and durability

The key to the pump's reliability is its solid construction. The motor housing made of stainless steel 316 (1.4401) provides high corrosion resistance, even in an aggressive environment. The impeller, also made of stainless steel (304 - 1.4301), guarantees durability and resistance to abrasion by solid particles contained in the pumped medium. The IP68 degree of protection means complete sealing and the possibility of continuous operation underwater. Insulation class F ensures safe operation of the motor even at high ambient temperatures (up to 40°C). The pump operates in S3 mode – cyclic, which means short-term operation under heavy load with breaks for cooling, which extends its service life.
