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.
