MQ3-35 On Demand Pump
This very reliable, compact, all-in-one, flow-based pump is designed for boosting water pressure. Ideal for boosting from water storage tanks (maximum 40 psi inlet pressure). It is a 3/4 HP single phase 115V pump with a rated flow of up to 18 GPM at low pressure and a max operating pressure boost of 45 psi at low flow. With an average performance of 5GPM at 40PSI it is ideal for many rainwater harvesters.
This unit is ideal for pressurizing water from a water storage tank, and boosting existing low water pressure.
- Low noise
- User friendly control panel
- Built-in, self protect function

The Grundfos MQ-3-45 is rated as high as 91.9ft of head. This pressure boosting system is a self-priming, multistage, centrifugal pump. It's capable of self-priming from a depth of 26 feet within 5 minutes. Well suited for pumping potable water and rain water. Easy installation. If exposed to dry running, excessive temperature, or any overload condition, the pump will stop automatically, preventing a motor burnout. Note: This pump should be used indoors or covered and insulated if used outdoors.
