HI 11.6-2017 applies to customer acceptance testing of rotodynamic submersible pumps driven by electric motors, unless otherwise agreed or specified. A submersible pump is defined as a close-coupled pump/motor unit designed to operate submerged in the pumped liquid. This definition includes submersible pumps operating in either a wet-pit or dry-pit environment. Excluded are deep well pumps, progressive cavity pumps and pumps not powered by an electric motor. A standard test measures pump performance from pump inlet to pump outlet and electrical input power. It does not include accessory items, such as outlet elbows, inlet fittings, or valves, unless specified by a contractual agreement. This standard also includes the acceptance criteria for original equipment manufacturer (OEM) factory and permanently installed pump vibration testing.

New to Standard

• The scope was expanded to include fractional and direct current motors.
• Symbols and equations are harmonized with ANSI HI 14.6
• Revised the default acceptance grades to 1U for permitted municipal water
• Added an informative appendix that provides examples to aid in the calculation of instrumentation uncertainties.

Applicable Markets: Pulp and paper, mining, wastewater as well as any industrial or residential application that must submerge a pump at the bottom of a well or chamber to pump out fluid or other viscous material.
