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.
1.3 PUMP IDENTIFICATION
Roto-Jet pumps are designated by a series of letters and numbers, such as
VSR 175-S375. The VSR 175 is an indication of the basic mechanical configuration and
the second group, S375, designates the pick-up tube inlet size. The pump nameplate gives
both the pump model designation and the pump serial number. For applications that use
the VSR 175 at a lower horsepower the designations will be similar to the following: VSR
175/140-S375 or VSR 175/120-S484. The 175 represents the model and the 140 or 120
represents the maximum operating horsepower. Refer to the Installation Instructions
manual for information regarding wiring. The remainder of this manual will refer to the
pump as the VSR 175.
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.

VSR 175 2
2. DISASSEMBLY/ASSEMBLY REFERENCE INFORMATION
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 pointed vertical and the
manifold is facing upward. Roto-Jet pumps offers assembly stands for mounting the unit
during disassembly and assembly.
