Product Overview
The Grundfos SCALA2 3-45 model 93013250 is a 208-230V variable-speed water booster that combines the pump, motor, pressure sensor, controller, and tank in one compact assembly. The integrated controller changes pump speed as fixture demand rises or falls, helping maintain the selected system pressure in a properly sized residential water-supply installation.
Confirmed performance data lists a rated flow of 13.2 GPM, maximum flow of 20.3 GPM, rated head of 88.59 ft, and maximum head of 147.6 ft. The “3-45” name is the model designation and should not be interpreted as a 3-to-45 GPM flow range. Actual flow and pressure depend on the complete duty point, including source pressure, elevation, suction conditions, pipe losses, and simultaneous demand.
This version operates on 208-230V single-phase power and has a confirmed maximum current consumption of 2.8A. The unit includes a 6.56 ft 230V power cord and is identified with NSF/ANSI 61 and 372 drinking-water approvals. Confirm the circuit, plug configuration, source-water conditions, system pressure, and required performance before installation. This product lists Grundfos 98562817 as a replacement reference; verify full compatibility before substitution.
