70E Pressure Booster
• Pre-engineered booster package offers shorter lead times 
• Low cost solution for large commercial pressure boosting applications 
• Flows up to 800 GPM with pressures up to 150 PSI
• Standardized duplex and triplex configurations 
• Uses horizontal 1531 (Close coupled end suction) pumps
• Pre-set PRVs
• Thermal relief system protects pumps from over heating
• Short circuit protection for each pump via fuses or circuit breakers

How does it work?
The system can be enabled to run automatically from the keypad, or remotely via "dry contact", or serial communication. Depending upon the water demand, the pumps stage on and off to maintain constant pressure in the building. PRVs (pressure regulating valves) are installed at discharge of each pump to regulate the required pressure.
Why use it?
To boost pressure of incoming city water and of the available hot water to meet the flow and head requirements through the day and night.
Typical application
Typical applications are: Schools, commercial and residential buildings, tank fed system conversion, bottling plants, pharmaceuticals, plastic injection molding facilities rain water re-use, etc.
