I have serviced several installations which looked identical to the QB 60 pump mounted on a pressure tank similar to the one I linked to. A centrifugal pump of that small diameter may not be physically capable of producing anywhere near the rated head. I strongly suggest adding a tank with a bladder such as:īTW that looks like a turbine pump. Maximum pressure may not occur at maximum flow. New here? Try reading these, they might help FAQ731-376: Forum Policies RE: Water pressure boost pump MikeHalloran (Mechanical) 10 Jan 17 22:00Ĭan you find a pumping curve for that pump? So which is the best alternative (anybody saying to compromise halfway up the hill will be asked to leave)? This is a 35l/min 35m head pump I am concerned about waterhammer when the pressure valve trips. Electrical power is not an issue there either, but it is a little more complex. Advantage of up the top is that we won't be able hear it. Advantages of by the house are that it doesn't pressurise the downhill pipe (1 inch black poly), and it can just run off an extension lead, and pumps like lots of head on the suction side. So we need to install a proper pump somewhere between the cold water tank at the top of the slope, and the house. The shower can run at 16 l/min, there is only one shower. So we tried the pump and got some miserable pressure reading. Then we looked at the spec of the yet to be installed instant gas hot water, and it needs at least 13m of head, and the plumber thinks that 24m is a more practical target. So, first thought was to bung in one of those 120W shower booster pumps, which theoretically can belt out 9m of head. LONG BORING BIT This makes showering a rather minimal experience. Check the non-return valves, and keep the ventilation holes free of dust.My off grid house is supplied with water from a tank about 6m above the shower head. MQ Successor requires no maintenance, but it is recommended to keep the pump clean. It is also possible to add external input control and schedule a pump operation via calendar function. With Grundfos GO, you can easily setup SCALA1 as a Twin booster system, operating as duty/stand by as well as duty/assist. The pump has a built-in motor protection that will stop the pump if exposed to excessive temperature due to high ambient temperature, in case of seizure or overload, thus preventing a motor burnout. Max runtime protection can stop the pump after a desired period of continuous operation, preventing potential damage due flooding in case of pipe breakages.Cycling protection which will prevent pump starting frequently in case of minor leakages in installation. Dry running protection that will automatically stop the pump in case of water shortage.SCALA1 Successor incorporates advanced protection features such as: SCALA1 can communicate with Grundfos GO app via built in Bluetooth, which enables detailed pump monitoring and high customization options, making this pump a good fit for every application. In city water or well water applications, use a PRLV-30, Pressure Reducing Limit Valve on the suction side of the pump to 30 PSI to prevent inbound water from exceeding the 43 PSI max inlet pressure. This facilitates easy installation and start-up of the pump and provides more reliable water supply in installations where there is a risk of dry running and leakages in suction hose or pipes. Provided it is filled with water, the pump can lift water from a depth of 26 feet in less than 5 minutes. The MQ Successor, SCALA1 is a self-priming, multistage pump, that incorporates all the components of a pressure booster into a compact composite enclosure.Īs it is self-priming, the SCALA1 and pump water from a level below the pump.
