Solving Low Water Pressure for Office Buildings, Large Apartment Buildings and More
Triplex Booster Systems ranging from 120-400 GPM. Great for multi-family buildings, condos, schools, hospitals, office buildings, hotels, and more.
Triplex 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.
Triplex booster pump systems are designed to lead, lag, and alternate every 24 HRS 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 desired pressure needed. Custom design options are also available.
Options available: NEMA 4x, BACnet modules, Modbus TCP/IP Modules, EtherNet/IP Modules, and more.
- 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
