Replacement Motor

This replacement booster pump is engineered to deliver reliable pressure augmentation for residential and light commercial water systems. Designed as a direct replacement for Grundfos SCALA2 units, this fully integrated, self-priming pump maintains consistent water pressure through intelligent variable-speed control technology, making it ideal for single-pump household applications serving up to 3 floors with 6-10 tapping points. The pump achieves a maximum head of 45 meters (147-148 feet) with rated flow capacity of approximately 13.2 GPM, expandable to 22 GPM depending on system configuration and performance curve requirements. Operating within ISO 9906 grade 2B compliance standards, the unit handles maximum inlet pressure of 6 bar (87 psi) and maintains system pressures up to 10 bar (145 psi) for optimal performance across multiple fixtures. Rated at 550 watts (3/4 horsepower), this pump operates on standard single-phase residential power and features water-sealed motor construction for safe, efficient operation. The self-priming design eliminates manual priming requirements and reduces installation complexity. Suitable for clean, fresh water applications with pH levels between 4 and 9, the pump maintains maximum operating temperature of 45 degrees Celsius (113 degrees Fahrenheit). This replacement unit is particularly well-suited for boosting low-pressure municipal supplies, improving shower pressure, and supporting multi-floor residential properties where consistent water delivery is essential. The compact, integrated design simplifies installation and maintenance while delivering the high-efficiency performance professionals expect from pressure booster systems. Ideal for homeowners and contractors seeking a reliable, code-compliant solution for residential water pressure applications.
