2. Apply rust inhibitor to all unpainted cast iron and

4-54. PACKING SPECIFICATION
Standard packing on all Moyno 2000 pumps consists of
braided PTFE fibers impregnated with ultrafine graphite.
Optional types of packing are available for food, high tem-
perature and other types of service. Consult your nearest
Moyno representative.
4-55. VARIATIONS OF STANDARD PARTS
Below are variations available for modifying pumps to
meet specialized pumping conditions. If the trim code of your
pump is other than “AAA,” contact your nearest Moyno
representative for clarification. Do not modify your pump
with any variation unless you have determined that it is com-
patible with your application.
The three-character trim code is designed as follows.
The first character identifies any sealing variations, the sec-
ond character identifies any internal variations, and the third
character identities any rotor variations.
The trim code ‘AAA” represents a pump with standard
features. Deviations from standard are to be indicated by
changing the appropriate character from the choices listed.
When two or more letters are combined, dashes are used to
separate the three areas of the trim code for clarity.

part number and changing the last digit of the rotor number
as follows:

Do not change rotor sizes without consulting your local
Moyno Sales Office. These variations are used for certain
