This Grundfos MQ pump is compact and extremely easy to install. The pressure switch and tank are built-in, and it is self-priming and water cooled with a very low noise level. The outlet pipe connection can be angled up to 5-degrees to fit your existing pipe-work, and it's simple and easy to operate. The settings are clearly indicated on the user friendly control panel with indicator lights for on/off, auto reset, and an alarm indicating dry running or overheating. The Grundfos MQ3-45 is built for trouble free operation, and its construction of corrosion resistant materials means it can be used for clean water. The anti-cycling feature prevents the pump from repeatedly starting and stopping in the event of a dripping tap or a minor leak, and in the even of no water availability, the pump will stop to protect itself and restart automatically when water is available again.
