Genuine Danner OEM Pondmaster & Supreme Replacement Mag-Drive Impellers | 10 Sizes

A common symptom of a submersible pump malfunctioning is when water stops being pushed, but the motor still hums. That hum almost always indicates that the pump's motor is still good but the impeller needs to be replaced.  

Installation is easy:

1) Use a Phillips screwdriver to take pump cover off intake (use a manual screwdriver to avoid stripping the screws). 
2) Pull old impeller out (may need pliers with more powerful Pondmaster models).
3) Make sure inner chamber is clean with no debris and smooth to the touch (with no pits or rough areas).
4) Check that O-Ring is still positioned along the housing. Apply a thin film of silicone grease along the surface of the O-Ring.
5) Then, simply insert new impeller into place and reattach pump cover.

Pro-tip : Also check inside of the pump cover because it may also be worn or damaged. Replaceable pump covers (aka:volutes) are available and other pond pump replacement parts can be bought from here.

For optimum preventative maintenance, it is recommended to replace both the impeller and the pump cover (volute).

While all of these impellers are very similar in design, it is very important you select the correct model!
