PANDA circulating pump

The PANDA series circulating pump is equipped with permanent magnet motors and a differential pressure regulator that automatically and constantly adjusts the performance of the pump to meet the system’s actual needs. The pump’s control panel is located on the side of the motor, making operation easy for the user. Its dial displays the current electricity consumption. The pump set includes a complete set of screw connections and an adapter for connecting the cable.

The pump provides 4 operating modes:
• AUTO (factory setting) - From highest to lowest proportional pressure characteristic curve
• Hs1 / Hs2 / Hs3 - Constant rotational speed curves
