Most people don't realize that most hybrid & magnetic drive pumps require occasional replacement of their impellers (also called rotors). It's a constantly moving part, especially in a year round water feature. Parts will wear out even in the cleanest of ponds given enough time.

Danner Manufacturing, the company behind the Pondmaster and Supreme brands, provides economical replacement parts for their pumps.

Available Impeller Models:

# 12770 for Pondmaster 4800 HY-Drive Pump
