These instructions are prepared for a pump with grease or
oil lubricated bearings and packed stuffing boxes. Optional
features are covered by separate instruction sheets which
are furnished when the equipment supplied includes these
features.
Model numbers used in Table I are for the commercial
pumps. Listed and approved fire pumps have the letters
“AEF” in place of “AE” in the model number. Many
models have suffix letters in the model number. These
suffix letters have been intentionally omitted from Table
I. However, when ordering repair parts, provide the
complete model number including suffix letters and the
pump serial number; both are stamped on the pump
nameplate.
