5.1.1 Pump Standards

Pump types are described or defined by various organizations and their respective publications:

• Hydraulics Institute (HI), American National Standard for Centrifugal Pumps for Nomenclature, Definitions, Application and Operation [American National Standards Institute (ANSI)/HI 1.1 1.5 1994].

• American Petroleum Institute (API), Centrifugal Pumps for Petroleum, Heavy Duty Chemical, and Gas Industry Services, Standard 610, 8th ed., August 1995.

• American Society of Mechanical Engineers (ASME), Centrifugal Pumps, Performance Test Code PTC 8.2 1990.

In addition, there are several American National Standards Institute (ANSI) and American Water Works Associations (AWWA) standards and specifications pertaining to centrifugal pumps:

• ANSI/ASME B73.1M-1991, Specification for Horizontal End Suction Centrifugal Pumps for Chemical Process.

• ANSI/ASME B73.2M-1991, Specification for Vertical In-Line Centrifugal Pumps for Chemical Process.

• ANSI/ASME B73.5M-1995, Specification for Thermoplastic and Thermoset Polymer Material Horizontal End Suction Centrifugal Pumps for Chemical Process.

• ANSI/AWWA E 101 88, Standard for Vertical Turbine Pumps Lineshaft and Submersible Types.

5.1.2 Pump Definitions and Terminology

Pump definitions and terminology, as given in Hydraulics Institute (HI) 1.1 1.5 1994 (Hydraulics Institute, 1994), are as follows:

Definition of a centrifugal pump. A centrifugal pump is a kinetic machine converting mechanical energy into hydraulic energy through centrifugal activity.

Allowable operating range. This is the flow range at the specified speeds with the impeller supplied as limited by cavitation, heating, vibration, noise, shaft deflection, fatigue, and other similar criteria. This range to be defined by the manufacturer.
