The Secoh SLL-40 Magnetic Rod Block is operated by 2 magnets that push the rod block back and forth as the coils engage and disengage at a rapid pace. This causes the diaphragms to push air in and out.
If you notice your Secoh SLL-40 Septic Air Pump is not properly pushing air in and out, there may be an issue with the Magnetic Rod Block. It is uncommon for this part to break, so many people do not assume it can be the cause of air pump issues. However, if your air pump has stopped working, you should check the Magnetic Rod Block right away.
If you have determined the Magnetic Rod Block is the cause of the problem in your Secoh SLL-40 Septic Air Pump, this Secoh SLL-40 Magnetic Rod Block is the exact replacement you need. This product comes with the Magnetic Rod block, and the screws necessary to replace your old one.
