The Pressurizer Water Booster Package - For water systems where additional pressure is needed. Amtrol's pressure boosting systems will increase the water pressure coming into your home or business as much as 40 PSI. Amtrol's pressure boosting systems can provide the solution to your low water pressure problem.The AMTROL High Performance Pressurizer is a true whole house pressure boosting system. The units are pre-assembled with a low-suction cutoff, thermal overload protection and built-in junction box. The Pressurizer includes a properly sized pressure tank to reduce pump cycling. This decreases power consumption while drastically improving motor life. Unlike small in-line models, this pressure tank provides additional water storage to meet peak water demands while improving efficiency. Specifications: Part Number: R4004 Model Number: RP-25 Flow Range: 3-17 GPM Width (in.): 24" Height (in.): 39" In Pipe Size: 1-1/4" Out Pipe Size: 1" Voltage: 115/230 H.P: 1/2 hp Pre-charge PSI: 38 On/Off PSI: 40/60 Max PSI: 100 Ship Weight (lbs): 99Note:To operate with lower water main pressure, pressure switch and tank pre-charge pressure must be adjusted. Minimum pressure is 5 PSI. Important:Systems are not to be used as part of a well system, unless a large storage tank is provided. The RP-25 system is designed to run continuously if demand exceeds 3 GPM.
