Grundfos MQ3-45 1 HP Pressure Booster Pump:
The Grundfos' MQ pump is compact and extremely easy to install. The pressure switch and tank are already built into the MQ. Furthermore, it is selfpriming and water-cooled with a very low noise level. The outlet pipe connection can be angled up to 5° to fit your existing pipe-work. The Grundfos' MQ pump is simple and easy to operate. The settings are clearly indicated on the user-friendly control panel with indicator lights for Pump on/off, auto reset, and an alarm indicating dry running or overheating. Grundfos MQ is built for trouble-free operation. It's construction from corrosion-resistant materials means it can be used for ultrapure water. The anti-cycling feature prevents the pump from repeatedly starting and stopping in the event of a dripping tap or a minor leak. If there is no water available, the pump will stop to protect itself and restart automatically when water is available again. The Grundfos MQ makes it easy to select the right water booster pump. The MQ is an all-in-one unit with two models to choose from. There is no need to worry about a separate pressure tank, pressure switch, electrical connections, fittings or any other separate items. With MQ, it is literally a matter of connecting the power and turning on the jet pump. Installation of an MQ pump is simple and can be done in a matter of minutes.
- The MQ pump has built-in dry-run protection. If the pump runs dry, the pump automatically stops.
- It will then attempt to restart every half hour for a maximum of 24 hours until water is available from the source.
- If more than 24 hours pass without water, the pump must be restarted manually.
- The auto reset function can also be disabled.
- The Grundfos MQ pump also has built-in thermal protection.
- If the pump overheats it immediately stops.
- After a 30-minute cooling-down period, the pump will automatically restart
- The Grundfos MQ is specially designed for use in domestic applications where low noise is a major consideration.
- The pump is cooled by the pumped water which eliminated the need for a noisy cooling fan.
- Since the pump is self-cooling, you don’t need to have free space around the pump for cooling purposes.
- The MQ "anti-cycling" feature prevents the pump from continuously starting and stopping when you have a dripping tap or minor leak in the system.
