INTRODUCTION

This manual is furnished to acquaint you with some of the practical ways to install, operate, and maintain
this pump. Read it completely before doing any work on your unit and keep it handy for future reference.

Equipment cannot operate well without proper care. To keep this unit at top efficiency, follow the recom-
mended installation and servicing procedures outlined in this manual. The SAM Engineering Customer
Service Department is available to expertly guide the installation of the pump for maximum operating life
and minimum downtime.

PUMP IDENTIFICATION (NAMEPLATE)

These pumps are designated by serial number, model, size, and M.O.C. This information is stamped on an
identification plate and affixed to the pump frame or casing.

Permanent records are kept by the factory and filed by serial number.
The pump nameplate contains the following information:

1. SERIAL NUMBER

– Composed of certain groups of numbers. All groups are necessary for

identification. TYPICAL EXAMPLE: P 2081 / 98

2. MODEL

– CSR, followed by SIZE – Composed of three (3) groups of number.

EXAMPLE: 4 x 3 x 11 – First number (4) is the ASA suction flange size in inches, second number (3) is

the ASA discharge flange size in inches, the third number (11) is the nominal maximum impeller

diameter in inches.

3. IMPELLER DIAMETER

– This number is the impeller diameter in millimetres as supplied by the factory.

EXAMPLE: 265

4. FLOW

– Design flow rate in cubic metres per hour.

5. HEAD

– Design head in metres.

6. MAX. DESIGN PRESSURE

– This refers to factory standard hydrostatic test pressure for hydraulic end

of pump.

7. M.O.C.

– Material of construction of pump shown in abbreviated form and in four parts.

EXAMPLE: CI/SS/CI/EN8 – where casing, stuff box and wear plate (if fitted) are in Cast Iron / impeller

in Stainless Steel / frame is in Cast Iron / shaft is in EN8

8. RPM

– Design speed of pump to achieve design flow and head.
