Grundfos Scala2 3-45 Pressure Pump

Grundfos SCALA2 Water Pump

A compact Grundfos water pump equipped with a constant pressure feature. The Grundfos SCALA2 is designed for water pumping and pressure boosting in single-family homes, vacation homes, farms, and greenhouses.

Thanks to its adjustable constant pressure feature, SCALA2 is the ideal choice for applications with multiple water outlets in use simultaneously. The water supply remains steady in the shower, even if someone flushes the toilet or the washing machine draws water at the same time. SCALA2 can deliver consistent water pressure to up to 8 water outlets across 3 floors. Its self-priming capability allows it to draw water from a well up to 8 meters deep. The package does not include flexible hose connections.
