Grundfos Unilift KP150-A1 0.14kW Submersible Drainage Pump with Float Switch (Max 140LPM/55kPa)

The Grundfos Unilift KP150-A1 is a compact, robust submersible drainage pump built for versatile performance in both temporary and permanent installations. Whether you need to manage grey wastewater, drainage water, surface water, or minor flooding, this lightweight yet durable pump delivers reliable operation in a wide range of domestic and light commercial applications.

Manufactured with a corrosion-resistant stainless steel housing and impeller, the Unilift KP150-A1 offers exceptional durability and long service life even in demanding environments. Its semi-open impeller design enables the safe passage of particles up to 10mm, making it ideal for handling non-aggressive wastewater from showers, sinks, washing machines, rainwater, and ground infiltration.

Equipped with an integrated float switch for automatic on/off control, the KP150-A1 ensures user-friendly operation, reducing the need for manual monitoring. The pump features a vertical 1¼" FBSP discharge outlet, a rugged carrying handle for portability, and a generous 5-metre mains cable fitted with an Australian plug for easy installation.

Internally, the pump is designed for maximum reliability, with a double shaft seal system (consisting of two lip seals with grease between them) and maintenance-free carbon bearings that are continuously cooled by the pumped liquid. The fully submersible motor, rated to IP68, includes thermal overload protection and is built to operate safely in water temperatures from 0°C to 50°C.

With more than a million Unilift KP pumps installed worldwide, the KP150-A1 continues to prove its reliability, energy efficiency, and minimal maintenance requirements in countless applications — from domestic sump pits to rainwater harvesting systems and emergency flood control.
