A pressure reducing valve can be added to the outlet to regulate the outlet pressure For systems with leaks an external 8 litre pressure vessel can be added to reduce pump starts. If required the automatic reset function can be deactivated. The pump can be set to automatically reset should the pump go into alarm, in which case the pump will attempt to restart every 30 minutes for a period of 24 hours. If the pump goes into alarm, the pump will be stopped and the red alarm indicator illuminated. The in-built protection protects the pump against water starvation, or if the motor overheats due to seizure of the pump shaft. The flow switch prevents on/off cycling of the pump with small demands. The pump continues to run until the pressure rises above 2 bar and the flow demand stops. The MQ3 controller starts the pump when the discharge pressure falls to approximately 1.5 bar. Flow switch reduces stop/start operations.Easy to install and maintain, Grundfos MQ3 is ideal for domestic or holiday home use. With no pressure tank or switch, fewer fittings are required for installation, minimising space. Grundfos MQ3 home booster pumps are convenient, compact, fully-integrated units which remove the requirement for a separate pressure tank and associated pipe fittings/connections.
