Grundfos 11SQF-2 1 HP Pressure Booster Pump

The Grundfos MQ3-45 1 HP Pressure Boost Pump is compact and extremely easy to install. The pressure switch and tank are already built into the MQ. 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 over-heating. 

Grundfos MQ is built for trouble free operation. It's construction from 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. If there is no water available, the pump will stop to protect itself and restart automatically when water is available again.

NOTE: Pump must be placed in area that will not freeze, as this will cause damage to the pump. Placing a pump in an area that is susceptible to freezing, WILL void the Grundfos warranty.

Compact and Easy Installation. Due to its compact design, the pump does not take up much space and is easy to install. No space around the pump is required.

Built-in Protective Functions. If exposed to dry running, excessive temperature, or any overload condition the pump will stop automatically, thus preventing a motor burnout.
Convenient All-In-One Design. The Grundfos MQ is a compact all-in-one pressure boosting unit, designed for domestic water supply and other boosting or lift applications.

User-Friendly and Simple Operation. The pump features a user-friendly control panel with ON/OFF button and indicator lights for indication of the operational state of the pump.
