Nomenclature, definitions, and scope has been summarized below.

End Suction Frame Mount (ESFM) [OH0, OH1]

End suction frame mounted/own bearings (ESFM) pump means a mechanically-coupled, dry rotor, end suction pump that has a shaft input power greater than or equal to 1 hp and less than or equal to 200 hp
at BEP and full impeller diameter and that is not a pool filter pump. Examples include, but are not limited to, pumps complying with ANSI/HI nomenclature OH0 and OH1, as described in ANSI/HI 1.1-1.2–2014, within the specified horsepower range.

End Suction Close Coupled (ESCC) [OH7]

End suction close-coupled (ESCC) pump means a close-coupled, dry rotor, end suction pump that has a shaft input power greater than or equal to 1 hp and less than or equal to 200 hp at BEP and full impeller diameter and that is not a pool filter pump. Examples include, but are not limited to, pumps complying with ANSI/HI nomenclature OH7, as described in ANSI/HI 1.1-1.2–2014, within the specified horsepower range.

In-line (IL) [OH3, OH4, OH5]

In-line pump means a pump that is either a) a twin-head pump, or b) a single-stage, single-axis flow, dry rotor, rotodynamic pump that has a shaft input power greater than or equal to 1 hp and less than or equal to 200 hp at BEP and full impeller diameter, in which liquid is discharged through a volute in a plane perpendicular to the shaft. Such pumps do not include pumps that are mechanically or close-coupled, have a pump power output that is less than or equal to 5 hp at BEP at full impeller diameter, and are distributed in commerce with a horizontal motor. Examples include, but are not limited to, pumps complying with ANSI/HI nomenclature OH3, OH4, or OH5, as described in ANSI/HI 1.1-1.2–2014, within the specified horsepower range.

Radially Split Multi-stage Vertical in-line diffuser casing (RSV) [VS8]

End suction close-coupled (ESCC) pump means a close-Radially split, multi-stage, vertical, in-line, diffuser casing (RSV) pump means a vertically suspended, multi-stage, single axis flow, dry rotor, rotodynamic pump that has a shaft input power greater than or equal to 1 hp and less than or equal to 200 hp at BEP and full impeller diameter and for the number of stages required for testing and in which:

  • liquid is discharged in a plane perpendicular to the impeller shaft;
  • each stage consists of an impeller and diffuser; and
  • no external part of such a pump is designed to be submerged in the pumped liquid.

Examples include, but are not limited to, pumps complying with ANSI/HI nomenclature VS8,
as described in the ANSI/HI 2.1-2.2–2014.

Submersible Turbine (ST) [VS0]

Submersible turbine (ST) pump means a single-stage or multi-stage, dry rotor, rotodynamic pump that is designed to be operated with the motor and stage(s) fully submerged in the pumped liquid; that
has a shaft input power greater than or equal to 1 hp and less than or equal to 200 hp at BEP and full impeller diameter and for the number of stages required for testing; and in which:

  • each stage of this pump consists of an impeller and diffuser and
  • liquid enters and exits each stage of the bare pump in a direction parallel to the impeller shaft.

Examples include, but are not limited to, pumps complying with ANSI/HI nomenclature VS0, as described in ANSI/HI 2.1-2.2–2014.
