Duplex Water Pressure Booster Pumps

Low Water Pressure Solutions from Homes to Hotels

Duplex booster pump systems ranging from 30-400 GPM. Great for multi-family buildings, condos, schools, hospitals, office buildings, hotels, and more.

Our Duplex Booster Pump System is equipped with centrifugal pumps, regulated by variable frequency drives that control the pump to maintain constant pressure regardless of varying demand or fluctuating incoming pressure.

Duplex booster pump systems are designed to lead, lag, and alternate every 24 hours of run time. This ensures even wear between each pump. In the event one pump cannot maintain the pressure, the second pump will turn on to assist.

The models below are a small sample of our available systems. Please call or email for more available options, or provide us with the performances you need. Custom design options are also available.

Options available: NEMA 4X, BACnet modules, Modbus TCP/IP Modules, EtherNet/IP Modules, and more.
