SynC · Topic
These are the standards in the SynC Standards library that cover Pumps. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide — ratings, materials, setpoints, and the standards each is verified against. All of it is free to read without an account and published under CC BY-SA 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
Stationary fire pumps installed to supplement an inadequate water supply for automatic sprinkler systems, standpipe systems, foam systems, or combined fire protection systems in commercial, institutional, industrial, and high-rise buildings. Covers horizontal split-case, vertical in-line, vertical turbine (line-shaft), and end-suction pump configurations driven by electric motors or diesel engines. Includes the pump itself, the driver, the controller (electric per UL 218 and NFPA 20 Chapter 10, diesel per NFPA 20 Chapter 11), the jockey (pressure maintenance) pump and its controller, suction and discharge piping arrangement within the fire pump room, the test header or flow meter loop required for periodic flow testing, automatic transfer switches where two utility services or a generator backs up the pump motor, and annual flow tests per NFPA 25.
Rotodynamic (centrifugal) pumps that circulate water and water-glycol solutions for building heating, cooling, and heat-rejection service. Covers closed-loop heating hot water and chilled water pumps, open-loop condenser water pumps serving cooling towers and fluid coolers, condenser loops serving water-source heat pumps, and the vertical turbine pumps used where the supply level sits below the pump. Addresses the pump end, the driving motor, the baseplate or frame, the coupling, shaft sealing, vibration isolation, factory and field acceptance testing, and the coordination items that decide whether the installed pump reaches its certified curve.
