Low Water Pressure Solutions from Homes to Hotels

Our Duplex Booster Pump Systems are equipped with centrifugal pumps, regulated by variable frequency drives that control the pumps 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.

We collaborate with mechanical contractors, engineers, architects, as well as facility owners to trouble shoot problems and find solutions, sometimes right over the phone that day.

We evaluate your situation and supply submittals and pricing on all our water booster pumps, typically within 48 hours and 8 out of 10 systems are built, programmed, tested and shipped within 1 week!

  • UL508 Rated VFDs
  • Modular Frame for Ease of Transport & Installation
  • Lead, Lag, and Alternate as needed
  • PLC is not required for networked Yaskawa VFD's Energy Efficient Operation
  • Plug-and-Play Installation
  • Pre-wired & Factory Tested
  • Properly sized pneumatic tank included
