Multi-Stage Pump Control …
Benshaw’s H2 Pump™ Series sets a new standard for multi-stage pump control applications. H2 Pump™ Series drives include application software designed to perform many functions — including advanced PID functions (eg. multiple pump or multi-stage pump control, lead lag, simplex, multiplex, triplex) — with the capacity of multiplexing up to eight (8) drives.
Advantages
Pumps are individually connected to AC drives, and a master drive controls the entire system:
- The pump is controlled by the unique PID function of AC drive, so external devices such as PLCs or contactors are not required
- The speed of each pump is controlled by individual AC drives to save energy
- Since the operating time of each pump is evenly distributed, the life expectancy of the pumping equipment is extended, reducing the total system operating cost
- If the master AC drive malfunctions, the next AC drive takes over as the master, and continuously controls the system without failure
The result? Cost savings (by reducing PLC’s and peripherals typically required to achieve these functions), as well as reduced maintenance costs, better system control and improved pump and pipe monitoring and protection. If you have one or multiple motors in a system that require constant pressure or flow, then this is the drive for you.
Benshaw H2 Pump™ Series Drives comply with key industry standards (UL/cUL/CE), offer built-in EMC filters (standard in all 480V models), standard RS-485 Modbus/RTU/BACnet/Metasys-N2 communication cards and a full range of programmable features.
