Replacement Impeller for the MAG-DRIVE / Pond-Mag / Aqua-Mag / Supreme:
Model 12 Submersible Pumps from E.G. Danner Manufacturing - Pondmaster.

  • Impeller Item # 12756
  • Replaces the Impeller on the following Pump Models:
    Model 12B Submersible Pumps: # 02712 / 02722
  • Includes the impeller fan with 6 blades, shaft, magnet and end bearings as one complete assembly
  • Approximate dimensions: 5.059" (128.5 mm) Total length - Magnet is 2.72" (69.13 mm) in length - Fan is 1.862" (47.30 mm) wide

All Pondmaster pumps will usually note on the label the following information on the label; this information does not specify the pump model as all models will have the same numbers or similar:

Listed 8C99

Model #'s such as 12 without a letter or with an "A" means its a first generation pump. If it has a "B" after the model it is 2nd generation. This is very important since the impellers are not cross compatible. The only models that are in 2nd generation are 9.5B, 12B, 18B.

Example of a label:


Question: Will the impeller fix my pump?

Answer: This depends on what signs your pump is displaying. Usually the pump will be rattling or vibrating with no flow or greatly reduced flow rate. You should unplug the pump and with dry hands open the pump cover by removing the screws on the front. Then pull out the impeller assembly. There should be some magnetic pull and if the impeller assembly comes out in multiple pieces or if a fan blade(s) are sheared or broken off or if the shaft is broken that should be a sign to change the impeller. Even if the there are no signs of damage, we recommend you do a pump test: Plug the pump in with the impeller assembly removed and place the impeller near the pump; it should shake which shows you that the pump is giving off magnetic pull. Promptly unplug the pump and an impeller assembly will probably fix your situation. If you don't get any magnetic shake from the pump than the pump is most likely defective and you should replace the entire pump as they cannot be repaired.


Question: Will removing the pump cover and/or impeller void the warranty?

Answer: No... Removing the pump cover and impeller is part of normal preventive maintenance and should be done every 6-12 months to keep your pump in perfect working order.
