Numbers and Titles



IncludesPumps and ancillary equipment for conveying and handling liquids for industrial, commercial, and municipal processes, where the pump is installed at a location not subject to flooding, submergence, or immergence. Includes various types of centrifugal, positive displacement, and reciprocating pumps. Level 2 numbers from 43 23 00 through 43 26 99.99 include pumps for conveying and/or compressing liquids for various types of processes. Centrifugal (rotodynamic) pumps may include open, semi-open, or enclosed impellers, recessed impellers, screw centrifugal impellers, or disc impellers
Alternate Terms/AbbreviationsCentrifugal pump: Rotodynamic pump: Volute pump. Overhung pump: End-suction pump (referring to overhung-impeller design). Flexibly-coupled: Pump employing flexible coupling on shaft. Rigidly-coupled: Pump employing rigid coupling on shaft. Foot-mounted: Not frame-mounted. Between-bearings pump: Split-case pump (referring to pumps with the impeller installed between bearings). Axially-split pump: Split-case pump, casing split parallel to pump shaft. Radially-split pump: Split-case pump, casing split perpendicular to pump shaft. Gear pump: Lobe pump.
