Grundfos KP250-AV-1 Automatic Submersible Pump (Flow 170 LPM)

The Grundfos Unilift KP submersible drainage pumps suitable for both temporary and permanent free-standing installation. They can be used for pumping drain water or grey wastewater. They are also suitable for installation in collecting tanks.

The KP is a lightweight pump designed specifically for drainage jobs. Its stainless steel surface makes it robust, durable and corrosion free, which reduces maintenance to an absolute minimum. More than one million KP pumps are installed worldwide and prove their reliability every day.

The Unilift KP is a single-stage drainage pump with semi-open impeller, designed for the pumping of drain water and grey wastewater. The Unilift KP-AV variant for narrow pits is supplied with a non-return flap valve for installation in the outlet. The strainer is clipped onto the pump housing.

Single-stage, submersible, stainless steel drainage pump in a robust design with upward-pointing discharge port positioned on the top of the pump.The outer casing is made in one piece. The mains cable and the cable of the level switch are both connected to a single, vulcanized, water-tight plug which is inserted in a socket on the hermetically-sealed stator housing. The motor is a single- or three-phase synchronous canned motor with liquid-filled rotor chamber and water-lubricated bearings.

The motor is cooled by the pumped liquid flowing around it. The motor incorporates automatic overload protection which cuts out the motor in the event of overload. When it has cooled to normal temperature, the motor restarts automatically.
