General name for pumps with one or more impellers. Many types and configurations for different applications. See below for specific centrifugal pump types.
ISO
Process
Pumps
02.
ISO Process pumps are the only dimensionally standard pump type in the European pump industry (e.g., comparable sizes of all manufacturers have identical envelope and interface dimensions.) ISO process pumps are, by definition, a horizontal, end suction, single stage pump. The pump meets ISO 5199 standard.
API Process
Pumps
03.
The API pump type applies to pumps built to the API 610 standard for pumps for refineries, pipelines, and other hydrocarbon processing applications. It includes end suction, horizontal split case, vertical turbine, and other types.
Axial Flow
Pumps
04.
Axial Flow pumps are a very high flow, low head type of pump. Also called a propeller pump.
Booster
Pumps
05.
Booster pumps are used to further boost the pressure in a system. It may be an end suction, in-line circulator, horizontal split case, or vertical turbine in a can type of pump.
Canned
Motor
Pumps
06.
Canned Motor pumps are sealless centrifugal pumps. The impeller is directly attached to the motor rotor, with a can separating the wetted rotor from the motor stator.
Chopper
Pumps
07.
Chopper Pumps are a type of centrifugal pump that is designed to chop up solids and stringy material as it pumps. It is available in a vertical column and end suction configuration.
Circulator
Pumps
08.
Circulator pumps is generally a pump with inline suction and discharge flanges.
End Suction
Pumps
09.
End suction pumps are the common type of centrifugal pump. Has horizontal shaft with overhung impeller. Flow goes in the end of the casing, and out the top.
Fire Pumps
10.
Centrifugal pump used for fire fighting in buildings, plants, and other locations. May meet UL/NFPA standards for fire pumps. Normally this is a horizontal split case or vertical turbine pump for UL/FM services. Non listed pumps may be end suction type.
