Grundfos Unilift KP150-AV1 0.14kW Submersible Drainage Pump with Vertical Lever Switch (Max 140LPM/55kPa)

The Grundfos Unilift KP150-AV1 is a high-quality, lightweight submersible drainage pump designed for the efficient pumping of grey wastewater, surface water, and non-aggressive liquids containing particles up to 10mm in size. Suitable for both temporary and permanent free-standing installation, it’s perfect for a wide range of residential, commercial, and light industrial drainage applications.

The KP150-AV1 model is equipped with a vertical float lever switch, ideal for use in narrow pits or tight spaces where traditional float switches are impractical. The vertical switch ensures automatic start and stop operation depending on water level, providing reliable, hands-free performance without requiring much space.

Built entirely from corrosion-resistant stainless steel, the Unilift KP150-AV1 is engineered for long service life, robust operation, and minimal maintenance. Its semi-open impeller design enables the passage of solids up to 10mm, making it highly effective for drainage tasks involving groundwater, rainwater, floodwater, domestic wastewater, and more.

Internally, the pump boasts a strong and efficient construction, featuring a double shaft seal with grease-filled chamber for enhanced motor protection. The rotor shaft runs in two maintenance-free carbon bearings, cooled continuously by the pumped liquid. The integrated submersible motor is rated IP68, ensuring safe and reliable operation under water, and includes thermal overload protection (Insulation Class F) for added peace of mind.

The Unilift KP150-AV1 is also fitted with a non-return flap valve at the outlet, helping to prevent backflow during operation. It comes ready for use with a 5-metre mains cable and Australian plug, and features a convenient carrying handle for easy transport and setup.
