B58.1-1961 (AWWA E101-61): American National Standard for Vertical Turbine Pumps - Line Shaft and Submersible Pumps (PDF)

This standard is recommended as a guide for users of the line shaft vertical turbine pump in selecting new equipment. The suggested standards are to be considered a minimum requirement for a first-quality vertical turbine pump, but do not preclude the use of more elaborate specifications on the part of either user or manufacturer, nor is it the intent to restrict the use of any equipment not meeting the requirements of this standard should the user not consider such compliance necessary.
