Scope of Standard: 

This standard includes recommendations for assessment of applied nozzle loads for the following pump types. When specified by the user, pumps supplied shall conform to these requirements.

  • Horizontal end suction single stage (ANSI/ASME B73.1 and B73.3).
  • Vertical in-line single stage (ANSI/ASME B73.2).
  • Axially split one and two stage (BB1).
  • Vertically suspended pump single casing discharge through column with diffuser and volute (VS1 and VS2).

Many other pump types are not included because of the different designs that are unique to each manufacturer. For pump types outside the scope of this standard, allowable nozzle loads should be established by the pump manufacturer, applied nozzle loads predicted by the purchaser, and differences, if any, negotiated and resolved by the two parties.

For assessment of applied nozzle loads for slurry pumps, see ANSI/HI 12.1-12.6 Rotodynamic (Centrifugal) Slurry Pumps for Nomenclature, Definitions, Applications, and Operation.


What You Will Learn/Overall Benefits:

  • Understand how nozzle loads effect pump operations under certain conditions
  • Facilitate conversation between manufacturer and OEM to determine an agreed upon level of loads

Applicable Markets:  Standard addresses entire pump community in all markets.
