UNILIFT AP12.40.06.A1 Submersible Pump

The Grundfos UNILIFT AP12.40.06.A1 submersible pump is a robust and efficient solution specifically designed for handling domestic wastewater. With a vertical single-cell design made from high-quality stainless steel (AISI 304), this pump is ideal for pumping non-aggressive water and grey water with particles up to 12 mm, making it suitable for both portable use and fixed installations. Its sturdy construction and advanced features make it a reliable choice for a wide range of dewatering applications in homes and buildings.

The pump's SEMI OPEN impeller allows for the effective handling of particles up to 12 mm in diameter, facilitating the pumping of groundwater, surface water, and rainwater. Additionally, the Grundfos UNILIFT AP12 is equipped with a suction strainer and a level switch that allows for automatic start and stop based on the liquid level, ensuring autonomous operation without the need for constant supervision.

One of the standout features of the UNILIFT AP12 is its double seal and the intermediate chamber filled with non-toxic oil, which protects the motor and internal components from potential leaks and wear, prolonging its lifespan. The pump also features a cooling jacket, which ensures continuous cooling of the motor through the pumped liquid, preventing overheating and ensuring safe and efficient operation.

This 0.9 kW dewatering pump incorporates a fully enclosed single-phase motor, designed to withstand continuous submerged conditions. It is protected by a Class F insulation system, with thermal overload protection, ensuring its reliability in prolonged use. Additionally, the ball bearings are lubricated for life, minimising maintenance needs and guaranteeing long-lasting performance.

The Grundfos UNILIFT AP12 is ready to use straight out of the box, as it comes equipped with a handle for easy transportation and a 10-metre power cable, suitable for both indoor and outdoor installation. The mains cable includes a glass-sealing compound in the socket, preventing moisture ingress into the motor windings, further enhancing its resistance and durability.
