The Grundfos Unilift KP.150.M.1 is a durable submersible drainage pump designed for clean water drainage, storm water handling and grey water applications. Constructed from high-quality stainless steel materials, this versatile pump is suitable for a broad range of domestic drainage duties and light industrial applications where reliable water transfer and dependable operation are required. Its compact design and corrosion-resistant construction allow it to be used in drainage pits, collection tanks and general water transfer installations where efficient fluid removal is essential.
Electrical performance is provided by a 0.15 kW (P2) motor operating from a standard 240V single-phase power supply while drawing a rated current of 1.3 Amps. Designed for dependable hydraulic performance, the system delivers a maximum flow rate of 142 L/Min through its 1¼ inch discharge connection. The hydraulic design simultaneously achieves a maximum head of 5.5 metres, providing efficient water transfer performance across a wide variety of drainage and water removal applications.
The hydraulic assembly incorporates a semi-open impeller specifically designed for drainage duties. This proven design permits the passage of solid particles up to 10 mm in size, allowing the pump to handle water containing small suspended solids commonly encountered in storm water and grey water applications. Working in conjunction with the stainless steel strainer, the hydraulic system is capable of reducing water levels down to approximately 100 mm, helping maximise the amount of water removed during operation.
Constructed using stainless steel components in contact with the pumped liquid, the pump provides excellent corrosion resistance and long service life. Certified to IP68 enclosure standards, the unit supports liquid temperatures up to 50°C and is suitable for submerged installation depths of up to 2 metres. This manual version is supplied without a float switch, allowing operation via external controls or manual switching where automatic level control is not required.
