These pond pumps are designed for use as water features and fountains. They are synchronous pond pumps, meaning the magnet rotor starts both clockwise and anticlockwise, depending on the current supply. The pumps are equipped with high quality, powerful nagnets and a ceramic shaft. A flexible control flap (FFS technology) supports the water flow independently of the rotation direction. This makes the pumps highly efficient, as no "positively guided" rotation in one direction is stipulated, the motor and rotor system are not subjected to unnecessary strain.
