Description
The Grundfos SCALA1 3-45 (SKU 99631742) is a compact, self-priming variable-speed water booster pump engineered to deliver steady, reliable water pressure in residential and light-commercial applications. Running on a standard 1x115V single-phase power supply with a NEMA 5-15 plug for easy installation, the SCALA1 eliminates the frustration of fluctuating water pressure caused by undersized supply lines, peak demand, or elevation changes.
How It Works
The SCALA1 uses an integrated variable-speed motor and an advanced electronic controller to continuously monitor and adjust pump speed, maintaining a constant outlet pressure regardless of demand fluctuations. The result is smooth, consistent water delivery throughout the entire system — from the first fixture to the last.
