Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If installed in drilling rig pumps
Parts specifically for oil/gas field boring machinery take precedence over general pump parts.
If quintuplex or other multi-plunger configurations
Different plunger counts may fall under other statistical suffixes for hydraulic pump parts.
If imported as unfinished forged casting
Unmachined steel forgings classify by material rather than as finished pump components.
