Danner Manufacturing, Inc., Replacement Impeller Part 12585 for Pump Models 02517, 02527 or 40127.

The support hole ends usually start to wear out, these rubber ends do wear some. So fair chance a new one will work awhile longer. Danner should include a few enlarged ends to make up for the hole size ! Or make a slip in metal collar so plastic does not wear out. Using these pumps since 1995. Average 4-6 years total life, with new impellers for me.

Good quality

Fit perfectly for my old pondmaster pump when the impeller froze up after about 20 years. I don't know how the old one siezed. Going to buy another one to have on hand.

As soon as I got this dropped into the place of the cracked impeller it was 100% read to live an all-new life, and with over 2000 gallons of ponds this pump is a fish life saver

After reading that this impeller would work with my discontinued Model 6 the order was placed and received the next day. Installation required a bit of fitting though. In the arrived configuration, 3 metal bushings on the outer end of the shaft, one on the inner side, the impeller would interfere with the body of the pump and not turn with electric applied. I discovered this after several disassembly/reassembly attempts and finally began swapping positions of the metal bushings, one at a time, until the impeller would freely turn. Final reassembly and application of electric and the pump was working, water once again flowing at the fountain. If you have a Model 6 and it's not working on initial installation, consider this adjustment to the impeller before you throw up you hands in despair. PS, hold onto the metal bushings for your old impeller should you need them.

Replaced existing impeller and pump work well again.

For some reason, the tiny "wings" broke off my Impeller. I took a chance and bought this part and it worked.

When I switched off my pump it was really difficult to get it going again without a lot of shaking and banging. This new impeller fixed the problem completely. Who knew? :-)
