SCALA2 Product description Grundfos SCALA2 is a fully integrated, high-efficiency, self-priming pressure booster. SCALA2 incorporates integrated speed control, enabling constant water pressure at the taps. The electronically controlled inverter limits the starting and operating currents, providing soft starts and high energy savings. The water-cooled motor and pump design offer a very low noise level down to 44 dB(A) in typical usage. Applications SCALA2 is designed for pressure boosting in one- and two-family homes, apartment buildings and light commercial buildings. We recommend using SCALA2 for the following applications: • pressure boosting of city mains water • pressure boosting of water from roof tank, break tank or ground tank • water supply from shallow wells (<8 m). Pumped liquids The pump is designed for pumping clean, thin, fresh water with a pH value between 4 and 9, a maximum chloride content of 300 ppm and free chlorine content below 1 ppm, for example: • drinking or tap water • rainwater • groundwater • river and lake water • softened water. Sand and other impurities in the water can cause wear to the pump and pump blockage. Therefore, we recommend that you install a filter on the inlet side or apply a floating strainer to protect the pump. Features and benefits Perfect water pressure SCALA2 has an integrated pressure sensor that monitors the pump outlet pressure and continuously adjusts the pump speed to maintain a constant water pressure at all taps. TM085889 GRUNDFOS DATA SHEET Low noise SCALA2 stands out as one of the quietest boosters in its size category in the market. The motor is water cooled and equipped with sealed, greased-for-life ball bearings, ensuring silent operation (44 dB(A) in typical usage). High energy efficiency SCALA2 is equipped with variable-speed drive which increases the entire pump system efficiency by eliminating wasted head and flow, and allows the pump to operate closer to its best efficiency point (BEP). Compact and easy to install SCALA2 is an all-in-one fully integrated plug-and-pump solution, eliminating any uncertainties found in traditional installations. SCALA pumps can be installed in four easy steps: 1. Connect the pipes. The inlet and outlet connections are adjustable by up to 5°, making the installation even easier. 2. Prime the pump. 3. Plug the pump into a power outlet, and start the pump. The default pressure setting is 3 bar (43 psi). 4. Adjust the tank precharge pressure according to the setpoint Robust design The pump is designed for long and trouble-free operation. The aluminium pump and stator housing combined with excellent corrosion-resistant internal components ensure high robustness in operation. Protective features and benefits SCALA2 is equipped with the following advanced protective features: • dry-running protection • thermal protection • micro-leakage detection.
