What is the PSI rating for each fire pump?

The correct answer is based on industry standards and guidelines for fire pump operations, as well as ensuring sufficient water pressure for effective firefighting. A fire pump’s PSI rating is significant because it determines the pump's ability to move water through the fire protection system with the necessary pressure to reach strategic points like fire hoses and sprinkler systems.

In many fire protection systems, a fire pump is typically designed to deliver water at a minimum pressure of 125 PSI. This pressure is deemed optimal for maintaining effective flow rates to ensure that the water can reach the height and distance necessary to tackle fires effectively. The 125 PSI rating supports a wide range of applications and is commonly used in various fire protection standards, making it a reliable choice for ensuring adequate fire suppression capabilities.

Other PSI ratings mentioned might represent specific applications or types of fire systems, but the 125 PSI rating is widely recognized as a standard that ensures operational effectiveness while providing adequate safety margins within fire protection systems. This makes it the correct answer for the question regarding the typical PSI rating for each fire pump.
