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.

1.1. 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.

1.2. PUMP IDENTIFICATION

Roto-Jet pumps are designated by a series of letters and numbers, such as 2200B-S484. The

first group, 2200A or 2200 B, designates the drive end radial bearing design. “A” is for direct

drive applications and “B” is for belt drive applications. The 2200 is an indication of the basic

mechanical configuration and the second group, S484, designates the pick-up tube inlet 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 REFERENCE INFORMATION

The following are recommended disassembly 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 disassembly 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 downward and the manifold is facing

upward. Roto-Jet pumps offers assembly stands for mounting the unit during disassembly and

assembly.
