    Reliable automatic drainage equipment is essential wherever water accumulation requires ongoing monitoring and removal. Functioning as a dependable submersible drainage pump, the Unilift KP.250.A.1 is designed for clean water drainage, storm water handling and grey water applications. Its corrosion-resistant stainless steel construction and automatic level control make it suitable for domestic drainage duties and light industrial installations where consistent water removal performance is required.

    The electrical drive system utilizes a 0.25 kW (P2) motor operating from a standard 240V single-phase power supply while drawing a rated current of 2.2 Amps. Designed for efficient water transfer, the hydraulic system achieves a maximum flow rate of 187 L/Min through its 1¼ inch discharge connection. Hydraulic performance is further supported by a maximum head of 7.5 metres, providing reliable operation across a broad range of drainage applications.

    Managing water transfer duties is supported by a semi-open impeller specifically designed for drainage applications. The hydraulic design permits the passage of particles up to 10 mm in size, making the pump suitable for handling water containing small suspended solids. Working together with the stainless steel strainer, the pump can reduce water levels down to approximately 100 mm, helping maximise water removal from pits, tanks and drainage areas.

    Constructed using stainless steel components in contact with the pumped liquid, the pump offers excellent corrosion resistance and long service life. Carrying an IP68 enclosure rating, the unit supports liquid temperatures up to 50°C and installation depths of up to 2 metres. A float switch provides automatic start and stop operation according to changing water levels, allowing dependable day-to-day drainage performance.
