About this file
This is a product specification document for the GRUNDFOS SCALA2 integrated water boosting pump. The SCALA2 is a fully integrated residential water booster pump designed to maintain consistent water pressure across all taps and fixtures simultaneously. The compact all-in-one unit combines pump, motor, tank, sensor, drive, and non-return valve into a single assembly measuring 11.9 inches in height, 15.9 inches in length, and 7.6 inches in width, weighing 22 pounds.
The SCALA2 features intelligent pump control that automatically adjusts operation based on inlet pressure and water consumption, operates at a noise level comparable to a modern dishwasher (47 dB(A)), and includes dry-running protection and anti-cycling capabilities for reliable operation. The pump is suitable for multiple applications including boosting from city mains, roof tanks, break tanks, ground tanks, rainwater tanks, and wells up to 26 feet in depth. Technical specifications include maximum ambient temperature of 131°F, maximum liquid temperature of 113°F, maximum system pressure of 145 psi, NEMA 3 rating for indoor and outdoor installation, and support for up to eight simultaneously open taps. Two model variants are available: model 98562818 (SCALA2 3-45 1x115V 60 Hz) and model 98562817 (SCALA2 3-45 1x208-230V 60 Hz). The pump operates with high efficiency using an ECM motor and is maintenance-free with a long operational lifetime.

SCALA2 is a fully integrated water booster pump providing perfect water pressure in all taps at all times—even with multiple taps and showers running at the same time. It packs pump, motor, tank, sensor, drive and non-return valve into one compact unit. And with its intelligent pump control, SCALA2 automatically adjusts performance to both inlet pressure and water consumption in the home. Thanks to a water-cooled motor, SCALA2 even offers one of the lowest noise levels of any booster on the market.
SCALA2 features a built-in sensor, which constantly measures the discharge pressure. If the pressure drops below the desired level, SCALA2 boosts its operation immediately to compensate for the loss of pressure. We call it intelligent pump control and the result is perfect water pressure.
SCALA2 is developed to deliver trouble-free operation and ensure a long lifetime. It is built from high-grade materials, and every pump is thoroughly tested to guarantee the best possible performance and quality.
