A suction in-line fire pump has a pressure range that can exceed 300 psi (2,068 kPa). This type of pump is a centrifugal pump that is installed in a vertical position with the suction and discharge connections in the same line. The pump is designed to handle high pressures and flows, and it is suitable for high-rise buildings and other applications that require high head.According to NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection, a suction in-line fire pump can have a rated pressure of up to 360 psi (2,482 kPa)1.The other types of fire pumps mentioned in the question have lower pressure ranges, as shown in the table below2:
