Locate the pump model number (found on the tag). A model number will look like this: AD941-920HI. The numbers after the dash are the wet end code. For example, the wet end code will look like this: 920HI. To select the correct replacement part in the large table below and to the right, find the wet end code from your pump in the first column. Then, find the USABlueBook stock number that corresponds to your replacement part. We show the most common wet ends; contact us if you cannot find yours.
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.
