Pump designs have largely been standardized. based on application experience, numerous standards have come into existence. As special projects and new application situations for pumps develop, these standards will be updated and revised. Common pump standards are:
1. American Petroleum Institute (API) Standard 610, Centrifugal Pumps for Refinery Service.
2. American Waterworks Association (AWWA) E101, Deep Well Vertical Turbine Pumps.
3. Underwriters Laboratories (UL) UL 51, UL343, UL1081, UL448, UL1247.
4. National Fire Protection Agency (NFPA) NFPA-20 Centrifugal Fire Pumps.
5. American Society of Mechanical Engineers (ASME).
6. American National Standards Institute.
7. Hydraulic Institute Standards (Application).
