B. INTRODUCTION
This instruction manual covers series E12L Series
Imo pumps. This series of pumps has been
designed for use in hydraulic, lubricating, and seal, applications requiring high inlet pressure
capabilities. The model and design construction of each pump can be identified by the designator
code on the pump nameplate. Definitions of model designators are identified in Figure 1.
C. DESCRIPTION OF EQUIPMENT
The E12L Series pumps are positive displacement, rotary screw pumps consisting of a precision
bored housing which 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.
