SCS90P-3

Multistage stainless steel pump with permanent magnet VFD control for steady household pressure.

The SCS90P-3 is driven by a permanent magnet variable frequency controller with five power levels, keeping pressure steady as demand changes. The water cooled motor and controller run quietly without a cooling fan, smart fault diagnosis reports abnormal conditions early, and the outlet can add up to 3.8 bar above inlet pressure.
