The Grundfos SCALA2 3-45-1 is an advanced, compact pressure boosting system engineered to maintain consistent water pressure in domestic water installations. By incorporating intelligent speed control, the pump automatically adjusts its performance based on real-time water demand, ensuring steady pressure even when multiple taps or appliances are in use.
SCALA2 is designed for fast and simple installation in just three steps: connect the pipes, prime the pump, and plug it in. Once powered, the pump begins operating automatically. Its fully integrated design includes a pressure tank, sensors, non-return valves, speed-controlled drive, and intelligent controller—eliminating the need for additional external components.
As a self-priming pump, SCALA2 can lift water from depths of up to 8 meters (26 ft) in less than five minutes when filled with water. This capability ensures reliable operation in installations where there is a risk of air in suction lines, leakages, or intermittent water supply.
Built-in protection features safeguard the pump against dry running, water shortages, overheating, and blockages. In alarm conditions, the pump automatically stops to prevent damage and initiates controlled restart attempts. The automatic reset function can be disabled if required.
Thanks to its optimized hydraulic design, permanent magnet motor, and water cooling system, SCALA2 operates at exceptionally low noise levels—as low as 44 dB(A)—making it suitable for both indoor and outdoor installations. The integrated pressure tank minimizes cycling, reducing wear and extending pump life. SCALA2 is maintenance-free, requiring only basic visual checks to ensure optimal long-term performance.
