Section I. GENERAL INFORMATION
1-1. Scope.
a. Type of Manual. Operator’s, Unit, Direct Support, and General Support Maintenance Manual.
b. Model Number and Equipment Name. Centrifugal Pump Unit, Water, 125GPM, Model No. 2X2 SP/52109,
NSN 4320-01-156-3873 (hereafter called pump unit).
c. Purpose of Equipment. The pump unit is a component of water distribution systems. It is used to transfer
drinking water from storage assemblies to distribution points.
1-2. Maintenance Forms, Records, and Reports. Department of the Army forms and procedures used for
equipment maintenance will be those prescribed by DA Pam 738-750, The Army Maintenance Management System
(TAMMS).
1-3. Corrosion Prevention and Control (CPC) of Army Material. Corrosion Prevention and Control (CPC) of
Army material is a continuing concern. It is important that any corrosion problems with this item be reported so
that the problem can be corrected and improvements can be made to prevent this problem in future items. While
corrosion is typically associated with rusting of metals, it can also include deterioration of other materials, such as
rubber and plastic.
Unusual cracking, softening, swelling, or breaking of these materials may be a corrosion
problem. If a corrosion problem is identified, it can be reported using Standard Form 368, Product Quality
Deficiency Report. Use of keywords such as “corrosion”, “rust”, “deterioration”, or “cracking” will ensure that the
information is identified as a CPC problem. The form should be submitted to the address specified in DA PAM 738-
750.
1-4. Destruction of Army Material to Prevent Enemy Use. Command decisions, according to tactical situation,
will determine when destruction of the pump unit will be accomplished. A destruction plan will be prepared by the
using organization, unless one has been prepared by higher authority. For general destruction procedures for this
equipment, refer to TM 750-244-3, Procedures for Destruction of Equipment to Prevent Enemy Use.
