High-Efficiency Circulating

The APUMP+ is a high-efficiency permanent magnet canned-motor central heating pump, for circulation of the primary water in a domestic heating system. Equipped with a differential pressure controller, the APUMP+ (when in auto setting) continuously adjusts its power input according to system load, to match the pump power to the system requirement. Alternatively, if required the installer or user can set the pump on a constant speed setting, between Min—Max levels.
