For impellers, a common symptom of a submersible pump malfunctioning is when water stops being pulled, but the motor still hums as if it's working. That hum almost always indicates that the pump's impeller needs to be replaced. Pump impellers or covers, sometimes referred to as volutes occasionally get damaged during operation. Danner Manufacturing's replacement impeller and covers are compatible with both Supreme & Pondmaster Pond-Mag Pumps.

If either your impeller or volute needs to be replaced, it is recommended to replace both items at the same time to prolong the lifespan of your pump. It is not uncommon for the damage or malfunction of one part to affect the operation of the second part because they work together.  

Each rebuild kit includes the appropriate model's replacement impeller and replacement volute with gasket assembly.
