Pump Genius software simplifies VSD pump applicationsWEG is releasing Pump Genius Software for use with its CFW-11 variable-speed drives (VSDs). This innovative process control software manages and monitors up to six pumps in a coordinated system. Pump Genius can operate motors from 5-150HP in the 208 and 230/240V AC range and motors from 5-600HP in the 480V AC range (approximately 3-112kW and 3-450kW, respectively). Because the CFW-11 drives have built-in PLC functionality there is no need for a separate controller.

Pump Genius is designed to reduce system operation and maintenance costs while increasing process accuracy and protection. The software provides control and protection as well as management of cycle hours and master and slave designation. It also monitors and controls system pressure or flow with available faults and alarms referencing low and high set points.

Rather than use conventional PLC-style programming languages, Pump Genius uses a wizard to take users through the configuration step-by-step, so the software can be used by non-programmers; even experienced engineers will find they can develop and implement a pump control system considerably quicker using Pump Genius. According to WEG, simple applications can be configured in as little as five minutes. Of course, significantly more complex applications can also be tackled, and it is estimated that Pump Genius is suitable for some 95-99 per cent of pumping applications.

WEG says that, unlike its competitors, Pump Genius software monitors the operating hours of all the pumps in the system, adding and subtracting pumps as demand changes, all without the need for setting a cycle timer. This feature ensures equal pump run times without supervision. Another key feature is the ability to have a floating master and slave rather than the traditional system of fixed master and slave pumps. Pump Genius automatically senses if the master is not responding due to sensor loss or other fault condition and assigns another pump to become the master, thereby maintaining operational continuity at all times during the process. The transition between master drives is done in a totally bumpless manner, without disturbing the process.

The CFW-11 VSD with Pump Genius software also monitors and alarms faults with the system, motor and drive, which will alert the operator to a potential problem. The drives are available in various sizes, from 2-600HP and include WEG's proven user-friendly graphic keypad HMI with large character graphics and readout.

In addition, all CFW-11 variable-speed drives have built-in DC link reactors which help mitigate the harmonic output on the AC line. They also have intelligent thermal management features that provide automatic cooling to the internal components of the drive.
