Fire pumps are essential to any building’s fire protection system. They provide the necessary pressure to ensure sprinklers and standpipes operate effectively during a fire emergency. One often-overlooked but crucial factor in fire pump selection and system design is the duty cycle. Understanding the fire pump duty cycle is key to ensuring your system performs reliably in real-world emergency scenarios.
