Basic Service Manual
Classic Series
INTRODUCTION
The Stenner Classic Series chemical feed pumps are mechanical and will, during their service
life, require scheduled maintenance. The purpose of this manual is to identify the five wear
parts (pump tube, roller assembly, lifter, cam, and index plate) that will eventually require
replacement, along with other maintenance basics. Best practice tips, such as a spill recovery
to eliminate chemical leakage, as well as corrective action techniques will be covered.
