This standard provides minimum requirements for submersible vertical turbine pumps utilizing a discharge column pipe assembly for installation in wells, water treatment plants, water transmission systems, and water distribution systems. Electric motors are the only type of prime movers addressed in this standard. It can be referenced in purchase documents for submersible vertical turbine pumps. Purchasers of submersible vertical turbine pumps that are intended to operate outside of the performance parameters and conditions defined in this standard are advised to consult with pump manufacturers familiar with the intended application conditions to modify the requirements of this standard as necessary for suitability with the specific conditions of intended use.<\/p>\n
