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.
