Grundfos Unilift KP 350 A1

The Grundfos Unilift KP 350 A1 Submersible Puddle Pump is a beautiful, impressive looking device. This lightweight single-stage pump can process both clean and slightly dirty water. The stainless steel pump body – made from one piece – makes the pump very robust, solid, and easy to maintain. It can be used in temporary and permanent freestanding setups and is also suitable to be installed in collecting tanks. The pump is fitted with a semi-open impeller that can process solids up to a diameter of 10 mm. This makes it ideal for pumping jobs in and around the house. The pump also has automatic overload protection, which switches the motor off if there is a risk of overheating. The motor automatically switches back on after it has cooled down to the correct temperature.
