Grundfos Unilift KP150-M1 0.14kW Submersible Drainage Pump Manual (140LPM/55kPa)

The Grundfos Unilift KP150-M1 is a lightweight, high-performance submersible drainage pump designed for both temporary and permanent free-standing installations. Suitable for a wide range of residential, commercial, and light industrial drainage tasks, this durable pump efficiently handles grey wastewater, rainwater, groundwater, and other non-aggressive liquids with solids up to 10mm in size.

Constructed from corrosion-resistant stainless steel, the Unilift KP150-M1 offers exceptional robustness and a long service life with minimal maintenance. The pump features a semi-open impeller, allowing it to pass small particles with ease, making it ideal for domestic effluent applications, sump drainage, tank emptying, rainwater harvesting, and flood control.

This manual version of the KP150 series is operated without a float switch, giving users full control over pump activation and shutdown — ideal for more specific or controlled drainage operations. The compact, ergonomic design includes a vertical discharge outlet (1¼" FBSP), a sturdy carrying handle for easy portability, and a 5-metre power cable with an Australian plug for quick installation.

Internally, the Unilift KP150-M1 is engineered for reliability and efficiency. It features a double shaft seal system (two lip seals with grease in-between), maintenance-free carbon bearings, and a motor continuously cooled by the pumped liquid, enhancing both durability and performance. The integrated submersible motor is rated IP68 for continuous operation under water and comes equipped with built-in thermal overload protection (Insulation Class F).
