Proper pump maintenance is essential for optimized performance and extended life. We recommend keeping essential repair parts on hand for quick access and reduced downtime.
To find the repair part you need:
First use your pump’s model number (found on the tag) to identify its wet end code. You’ll find the wet end code after the dash (e.g., AD941-920HI). Then use the tables and diagrams to select the part that’s compatible with your pump’s specific wet end.
If you don’t see your pump’s wet end code, or need assistance in selecting the correct repair part, we’re here to help. Just give us a call at 800-548-1234.
