ROTO-JET PUMP
DISASSEMBLY/ASSEMBLY
Model R11
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.

R11 2x2 2
1.3. PUMP IDENTIFICATION
Roto-Jet pumps are designated by a series of letters and numbers, such as R11-
S252. The first group, R11, is an indication of the basic mechanical configuration
and the second group, S252, 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.
