Centrifugal Pumps
 N PTC 8.2

Annotation

Prepared in accordance with ASME PTC 1 on General Instructions, this Code provides standard directions for conducting; and reporting performance tests of centrifugal pumps, including those of the mixed flow and axial flow types; hereinafter inclusively covered by the term "pumps."

The objective of this Code is to establish rules for conducting tests of pumps to determine, under specified conditions, the following characteristics:

(a) total head produced by the pump;

(b) pump capacity, (rate of flow through the pump);

(c) power input to the pump;

(d} efficiency;

(e) net positive suction head requirements of the pump.

The above characteristics are hereinafter inclusively covered by the term "performance."

In addition to the foregoing, this Code provides nonmandatory appendices which provide additional guidance related to the application of this Code.

This Code applies to the testing of pumps utilizing liquids or mixtures of miscible liquids which have Newtonian viscosity characteristics.

If specific directions in this Code for any particular measurement differ from those given in a reference code for similar measurements, the instructions of this Code shall prevail. It is the intent of this Code that the meaning of all terms be understood and applied as defined in Section 2 of this Code.

This Code mandates testing procedures and acceptable instrumentation for tests designated Type A and Type B. Subsequent reference in this Code will be made to these as Type A and Type B (see Section 3). Prior to the test, the parties to the test must agree in writing to the type of test to be conducted. If this Code is invoked without reference to type, the test shall be conducted in accordance with criteria estabIished for Type A.
