Grundfos MQ Jet Pump The pump starts automatically when the water is turned on and stops when the flow stops. The MQ is a low-noise pump. The pump is self-priming and has a built-in check valve. The pump is cooled by the pumped water which eliminates the need for a noisy fan. Because the pump is self-cooling you don't need to have free space around the pump for cooling purposes. And because the pump will keep running down to very low flows, this overcomes problems of cycling. The pressure tank incorporated in the pump reduces the number of starts and stops in case of leakage.
Built-in dry-run protection If the pump runs dry it automatically stops. It will attempt to restart for a maximum of 24 hours until water is available from the source. If more than 24 hours pass without water it must be restarted manually. The auto reset function can also be disabled.
Built-in thermal protection If the pump overheats (dry running, overtemperature of liquid, overloaded motor, locked rotor condition) it immediately stops. After a 30 minute cooling-down period, the pump will automatically restart.
