DB22 PART NUMBER EXPLANATION
NOTE: Pump end includes wetted components, drive magnet and motor adapter; wet end includes wetted components only.
Base model number contains standard components. Where standard components aren’t suitable, add the alternative component
code letter after the base model number to substitute components. Example: DB22P-E-U-21 is constructed of the listed base model
components except it has an EPDM O-ring, union connections, and a 213TC motor adapter.
Part Number Explanation
The model number is on the serial number label
located on the motor adapter. The model number
contains a base model that features certain stan-
dard components. Compare the model number
on the pump to the adjacent chart to determine
if the pump contains any alternate components.
Model numbers containing “P” have primary
components molded from polypropylene. Model
numbers containing “V” have primary compo-
nents molded from PVDF.
Base Model Numbers: DB22P, DB22V
