Cleaning
Mag Drive pumps will require periodic cleaning of the magnetic rotor and rotor chamber.
Please follow the directions below for proper cleaning procedures:
• Unthread the pre-filter by turning it in a counter clockwise direction.
• Remove volute by rotating it in a counterclockwise half turn while pulling lightly outward
from the pump body.
• Remove the impeller assembly from the rotor chamber.
Note: The impeller assembly is comprised of six individual parts shown in the image below.
Take care not to lose or misplace any of these pieces during the cleaning process.
• Inspect the magnetic rotor and the rotor chamber for built up debris. Loose debris can be
flushed out with clean water. Often in hard water, well water or pond-free applications,
debris may appear as a crusty film around the rotor and in the rotor chamber. Remove
this film using a scrub brush and white vinegar.
• Inspect the intake O-ring for nicks or breaks.
• Re-assemble the impeller assembly insert it into the rotor chamber.
• Attach the volute by applying pressure and rotating it in a clockwise half turn.
• Replace the pre-filter.
