Pump Description
This instruction manual covers the D3EICS-162 pump.
The D3EICS-162 pump is a positive displacement, rotary screw pump consisting of a precision machined
housing 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, the fluid is moved
axially from the inlet port to the outlet port in a continuous, uniform flow with minimum fluid pulsation and
pump noise. Fluid flowing through pump provides lubrication for moving parts. Normal rotation of pump is
clockwise as viewed from the shaft end. It is assumed by Imo that fluid this pump will be used on is not
hazardous in any way, nor is fluid considered flammable. Environmental or health risk associated with fluid
spillage or contact is not considered as part of Imo Pump's hazard analysis. Imo Pump must approve use
in any other service.
GENERAL INSTRUCTIONS
Instructions given herein cover generally operation and maintenance of subject equipment. Should any
questions arise which may not be answered specifically by these instructions, they should be referred to
Imo Pump for further detailed information and technical assistance.
This manual cannot possibly cover every situation connected with operation, adjustment, inspection, test,
overhaul and maintenance of equipment furnished. Every effort is made to prepare text of manual so that
engineering and design data is transformed into most easily understood wording. Imo Pump, in furnishing
this equipment and this manual, must presume that operating and maintenance personnel assigned
thereto have sufficient technical knowledge and experience to apply sound safety and operational
practices which may not be otherwise covered herein.
In applications where Imo Pump furnished equipment is to be integrated with a process or other
machinery, these instructions should be thoroughly reviewed to determine proper integration of equipment
into overall plant operational procedures. On critical or dangerous equipment, provide suitable safety and
emergency systems to protect personnel and property from injury due to pump malfunction. If pump
handles flammable, toxic, corrosive or explosive fluids, provide for safety in event of pump leakage or
malfunction.
WARNING
If installation, operation and maintenance instructions are not correctly and strictly followed and
observed, injury to personnel or serious damage to pump could result. Imo Pump cannot accept
responsibility for unsatisfactory performance or damage resulting from failure to comply with
instructions.
ORDERING INSTRUCTIONS
To order replacement pump, contact an Imo sales office or representative with pump model number and
serial number. This information can be found on pump nameplate and in this manual. Major and minor
kits are also available.
LIQUID LIMITATIONS
Never operate on water. Pump is designed for liquids having general characteristics of lubricating oil or
distillate fuel oils.

OPERATING PARAMETERS
CAUTION ATTENTION
Operating conditions, such as speed, fluid viscosity, temperature inlet pressure, discharge
pressure, filtration, duty cycle, drive type, mounting, etc., are interrelated. Due to these variable
conditions, the specific application limits may be different from that of the operational limitations.
This equipment must not be operated without verifying system’s operating requirements are within
pump’s capabilities.

INSPECTION
Interval for inspection and replacement of worn parts varies with properties of pumped liquid and can only
be determined by experience. All internal parts of 3E pumps are lubricated by pumped fluid. Pumping liquid
which contains abrasive materials or liquid that are corrosive, will significantly reduce service life and call for
shorter service intervals. A worn pump will be noticeable by excessive vibration, noise, reduction of flow
output and/or reduction in system pressure.
PUMP MAINTENANCE
WARNING
Failure to observe precautions while installing, inspecting, and maintaining pump can cause injury to
personnel from accidental handling, e.g.: Liquids that may harm skin or clothing, fire hazard risks
from flammable liquids, or injury from high pressure fluid jets.
DANGER
Failure to observe precautions noted in this box can result in severe bodily injury or loss of life.
Note: Part number identifiers (IDP’s) contained in Table 1 and shown within parenthesis such as (01)
refer to circled numbers shown on Assembly Drawing.
NOTE: If upon disassembly, significant wear on power, idler rotors and rotor housing is found, Imo
Pump recommends replacement of entire pump.
TOOLS REQUIRED
Procedures described in this manual require common mechanics hand tools, arbor press, torque wrench and
a suitable lifting device such as a sling.
PUMP DISASSEMBLY, See ASSEMBLY DRAWING
NOTE: The 3E Series pumps incorporate highly finished precision parts that must be handled
carefully to avoid damage to critical machined surfaces. Parts removed should be tagged for
identification and their exact positions in pump carefully noted so that new parts, or removed
parts can be properly replaced.
The following steps are required before starting any maintenance action:
A. De-energize and lock out power to driver and tag power control box “WARNING - Out of Service”.
B. Close all inlet and outlet valves and tag valves “WARNING - Out of Service”.
3
Fluid leakage from disassembly of pump may make floor slippery and cause personal injury
CAUTION ATTENTION

C. Remove pipe fittings/flanges at pump inlet and outlet openings.
D. Remove bolts holding pump to its mounting.
E. Remove key (13) from power rotor (7) shaft and locate pump on a suitable workbench
F. Drain pumping liquid from pump.
1. Remove bolts (027) and cover (004) from case (001). Remove O-ring (026) from either case
(001) or cover (004).
2. Remove power rotor (007) and idlers (008) as a set from housing (075). Take care not to drop
idlers (008) as rotor set is removed from housing (075).
3. Remove bolts (003) and cover (002) from case (001). Clean Loctite Gasket Eliminator from
cover (002) and flange of case (001).
4. Remove housing (075) from inlet end of case (001) and O-ring (076) from housing (075)
Pump Reassembly, See Assembly Drawing
NOTE: Prior to pump assembly, all parts should be cleaned and inspected for nicks, burrs or
gouges. When ready for assembly, wipe all parts, including bolts, O-rings and seal faces
with clean, Lubricating oil or pumped product, if applicable.
1. Install O-ring (076) on groove in housing (075) and housing (075) in inlet end of case (001) ensuring
