Pump Drives for Maximizing Energy Efficiency

Energy efficiency is optimized because pump output is precisely modulated to meet exact system demands

 

UnigyTM - Definition of Pumping Efficiency
Unigy
TM pump drives are a computerized controller with integral drive that maintains system pressure without using unnecessary and excess flows. The system collects thousands of data points during each motor shaft revolution and monitors the motor loading, accurately reflecting hydraulic system demands. Using a set of proprietary algorithms the computer continuously evaluates the data stream coming from the motor and constantly regulates amperage and voltage. The computer seamlessly and automatically controls motor speed and torque – and therefore pump flow and pressure.

Significantly reduced hydraulic system design, installation and maintenance costs.
Because excess flow has been eliminated to meet an application's peak flow and pressure requirements, there are no bypass valves or fluid circuits needed for pump control.  This translates into fewer connections and overall simplification of the fluid system. Another consequence of this efficiency is reduced pump wear - everything lasts longer, increasing the intervals between periodic maintenance.

3) Noise reduction improves work place environment.
Unigy
TM pumps only operate when the system requires it and when compared to systems that run continuously, there's much less noise.  Beyond that, they actually cause the pump to operate quieter because the lag time and control tolerance associated with conventional variable frequency drives is eliminated.  What type of difference can UnigyTM really make?  A recent pump test measured approximately 92 dBA one meter away and high from an 8 GPM at 700 PSI pump system.  That same system, when operated with a UnigyTM drive was below 80 dBA.
