1. GENERAL
1.1. INTRODUCTION
This manual has been prepared to assist you in understanding the construction and
the correct methods of disassembly and assembly for your new Roto-Jet pump.
The Roto-Jet pump is the simplest and most reliable high pressure pumping device
ever invented. The design, material and workmanship incorporated in the
construction of Roto-Jet pumps makes them capable of giving long, trouble free
service. The life and satisfactory service of any mechanical unit, however, is
dependent upon correct application, proper installation, periodic inspection and
careful maintenance.
We urge you to read and follow all of the directions in this manual. If additional
copies are required or other detailed instructions are needed, the information may
be obtained upon request.
1.2. ROTO-JET PUMP DESIGN
The exclusive patented Roto-Jet pump has only two basic working parts...a rotating
case and a stationary pick-up tube collector arm within the rotating case. The Roto-
Jet design completely eliminates the need for packing glands, wear rings or multiple
stages as used in conventional centrifugal pumps, and also eliminates the complex
pistons, rods, valves and springs required in reciprocating pumps.
The Roto-Jet operates in the following manner: Liquid enters the intake manifold
and passes into the rotating case where centrifugal force increases the pressure of
the liquid and at the same time its velocity is increased. The velocity of the liquid in
the rotor is converted into additional pressure as it jets into the pick-up tube.

RO 4x3 2
1.3. PUMP IDENTIFICATION
Roto-Jet pumps are designated by a series of letters and numbers, such as ROA-
S484. The first group, ROA, is an indication of the basic mechanical configuration
and the second group, S484, designates the pick-up tube size. The pump
nameplate gives both the pump model designation and the pump serial number.
Permanent records for this pump are kept by the serial number and it must therefore
be used with all correspondence and spare parts orders. This will ensure
replacement of components in the original materials of construction.
2. DISASSEMBLY/ASSEMBLY
2.1. GENERAL
The following are recommended dismantling and assembly instructions for your
Roto-Jet pump. We urge that the instructions be read thoroughly before attempting
to dismantle the unit. The component parts must be handled with care during the
dismantling and assembly process. The work area should be clean and be
equipped with the required tools.
Depending on the accessibility of the pump and the extent of the repair or inspection
required, the pump can be dismantled in place on its foundation. However, to
facilitate the disassembly procedure, it is recommended that the pump be removed
from its foundation and placed securely into a position in which the pump shaft is
facing downward and the manifold is facing upward. Roto-Jet pumps offers
assembly stands for mounting the unit during disassembly and assembly.
CAUTION
READ THESE INSTRUCTIONS CAREFULLY BEFORE BEGINNING WORK
ON THIS ROTO-JET PUMP. OBSERVE ALL INSTRUCTIONS
PARTICULARLY SAFETY RELATED INSTRUCTIONS OR CAUTIONS AND
USE SAFE SHOP PRACTICES.

2.7. CAUTIONS
The following precautions are recommended to insure continued satisfactory
operation of unit after reassemble.
WARNING
PLEASE STUDY THESE INSTRUCTIONS CAREFULLY BEFORE PERFORMING
PUMP MAINTENANCE. ADHERENCE TO THESE INSTRUCTIONS IS
NECESSARY FOR SATISFACTORY REPAIR OF YOUR ROTO-JET PUMP.
MAINTENANCE PERSONNEL MUST READ AND UNDERSTAND THE ASSEMBLY
AND DISASSEMBLY SECTION.
WARNING
WHEN PERFORMING EQUIPMENT MAINTENANCE OR IF THE PUMP IS TO
REMAIN OUT OF SERVICE FOR A PERIOD OF TIME, THE EQUIPMENT
ELECTRICAL SERVICE MUST BE LOCKED OUT WITH AN APPROVED
LOCKOUT AND KEY. FAILURE TO LOCKOUT EQUIPMENT MAY RESULT IN
INJURY.
2.7.1. Do not re-use o-rings on components during reassembly as they lose their seal
integrity and may leak.
2.7.2. When replacing pick up tube, always replace pick up tube capscrews to avoid
attachment complications.
2.7.3. Never re-use bearing locknuts when replacing bearings as they lose their positive
locking capability when removed.
2.7.4. During rotor cover removal mark location of cover on rotor and location of each
capscrew so that they can be assembled in same location. Failure to do this may
create an out of balance condition making pump susceptible to vibration damage.
2.7.5. Replacement of major rotating component such as shaft, rotor or cover will
require rebalancing of rotating assembly.
2.7.6. Be sure all parts are free of dirt, stray metal chips or any foreign matter and have
been thoroughly cleaned.
2.7.7. All torque values given assume lubrication with an anti-seize agent to threads and
underside of bolt heads.

RO 4x3 15
2.7.8. WARNING: When lifting the pump into the vertical position with or without the use of the
assembly stand a swivel hoist ring shall be used in place of the lifting eye. Reference
APPENDIX A Drawing.
WARNING
THE EYE-BOLT HOLE LOCATED ON THE TOP OF THE PUMP HOUSING IS
INTENDED FOR LIFTING THE PUMP ONLY, AND NOT THE COMPLETE
PUMP AND BASE PACKAGE.
WARNING
EQUIPMENT LIFTING DEVICES SUCH AS CHAIN, LIFTING EYES, HOOKS,
ETC. MUST BE APPROVED BY LOCAL, STATE OR FEDERAL SAFETY
CODES.
HOISTS AND CRANES MUST BE ADEQUATELY SIZED TO LIFT RATED
LOADS.
FAILURE TO USE APPROVED LIFTING DEVICES MAY RESULT IN INJURY.
WHEN LIFTING THE PUMP, IT IS IMPORTANT TO MAKE SURE THAT THE
CHAIN AND CABLES ARE FASTENED RELIABLY TO THEIR RETAINING
HOOKS.
2.8. SEAL REPLACEMENT
WARNING: Before lifting the pump into the vertical position first remove the
lifting eye and install the swivel hoist. When tightening the swivel hoist ring,
torque to 100ft-lbs. Once the pump is re-assembled and in the horizontal
position remove the swivel hoist and re-install the lifting eye. Reference
APPENDIX A Drawing.
2.8.1. General Instructions
2.8.1.1. Lock out and tag drive.
2.8.1.2. Remove drive connection to pump (belts or flexible coupling).
2.8.1.3. Remove inlet and discharge lines from manifold. Remove seal flush
lines and drainage piping if applicable.

RO 4x3 16
2.8.1.4. Seals may be changed with pump in horizontal (mounted) position or
removed from mount and secured in position in which pump shaft is
facing downward. The steps for replacing seal remain the same.
However, extreme care must be taken to avoid face damage during
handling of pump components in the horizontal position.
2.8.1.5. Drain oil before removing pump from base.
2.8.2. Disassembly - Manifold
2.8.2.1. (Flanged manifold only) Remove 4 bolts (61) from the end of the
manifold (36). Now the plug (33) can be removed.
2.8.2.2. Remove the 11 socket head capscrews (40) which secure the pick
up tube (1).
2.8.2.3. Push pick up tube (1) inward until free of o-ring (49). Recommended
use of pick up tube guide (P/N 0663676).
2.8.2.4. Remove 4 hex nuts (45) which mount manifold (36) to endbell (26).
2.8.2.5. Pull manifold (36) away from endbell (26). When manifold (36) is
free of studs (32) remove pick up tube o-ring (49) and place manifold
(36) aside.
2.8.3. Single Stationary Seal 4x3 pump (reference figure 2.6.1.)
2.8.3.1. Remove 10 set screws from seal mating ring carrier (76) and then
remove mating ring, carrier (76) and o-ring (83) from seal hub (29).
The seal mating ring can separate from the carrier while being
removed from the seal hub. If it does, remove the seal mating ring
from the seal hub before proceeding and slide seal mating ring back
in to carrier.
2.8.3.2. Remove 2 socket head capscrews (67), then remove seal plate (24)
and seal cartridge (75) from the endbell (26).
2.8.3.3. Remove seal cartridge (75) and 0-ring (50) from seal plate (24).
Clean seal cavity.
2.8.3.4. Replace seal hub (29) , if required, seal hub radial runout must be
checked and adjusted as required. Reference section 2.8.4 for seal
hub replacement.
2.8.3.5. Install new o-ring (50) in seal plate (24). Apply light oil to seal cavity.
2.8.3.6. Install and seat the seal cartridge (74) in seal plate (24). Caution
should be taken to avoid chipping face.
