Read this entire bulletin 

before  attempting  to  repair  this  pump.  For installation 
and  operation  refer   to   instruction   bulletin   2880549.  
Properly installed, your Peerless Pump will give you 
satisfactory, dependable service. We urge that you care-
fully read these step-by-step instructions, to simplify any 
problems of installation, operation or repair. 
 
Failure to read and comply with installation and 
operating instructions will void the responsibility of the 
manufacturer and may also result in bodily injury as well 
as property damage. 
 
This bulletin is intended to be a permanent part of your 
pump installation and should be preserved in a 
convenient location for ready reference. If these 
instructions should become soiled, obtain a new copy 
from  Peerless Pump Company include pump model 
and/or serial number with your request.

These instructions are prepared for a pump with grease 
or oil lubricated bearings and mechanical seals in the 
stuffing boxes. Optional features are covered by 
separate instructions sheets which are furnished when 
the equipment supplied includes these features. 
 
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.
