INTRODUCTION 
 

This instruction manual covers the C324AXFX-250/12005 pump.  

 

DESCRIPTION OF EQUIPMENT 
 

C324AXFX-250/12005  pump is a  positive  displacement, rotary screw pump consisting of precision bored 
housings that encloses a driven screw (power rotor) and two intermeshing following screws (idler rotors).  
These screws when rotating form a succession of closures or cavities.  As they rotate, fluid is moved axially 
from inlet port to outlet port in a continuous, uniform flow with minimum fluid pulsation and pump noise.  
Fluid flowing through pump provides lubrication to moving parts.
