The Patterson Pre-Pac® Fire Pump was created to provide highly efficient, quality fire control in an economical package at less cost and in less space. Unlike conventional pumping systems, it is self-contained, so it saves money by reducing labor, engineering and installation time. The Pre-Pac is built in a controlled environment, providing single source responsibility. It is pre-engineered to meet, or exceed, all applicable codes. For an added measure of security, it is completely tested in accordance with NFPA 20 and all piping is hydrostatically tested. The system features Patterson's split case or vertical turbine pump, featuring discharge pressures of 40 to 390 psi and capacities of 150 to 5,000 gpm.Patterson Pump Co.
