CONTROL SOFTWARE optimises pump efficiency
Process control software from WEG reduces operation and maintenance costs while increasing accuracy
G
lobal leader in automation and control technologies WEG has
launched Pump Genius process control software which enables engineers to optimise their pumping systems so they run more efficiently. The software is designed to reduce operation and maintenance costs while increasing process accuracy and protection. The software works with WEG’s CFW11
drive to provide multiple pump control and protection as well as system monitoring. Pump Genius can be applied to any system that requires constant flow or pressure and manage and monitor up to six pumps in a coordinated system. Using the software with pumps in
parallel increases the flexibility of the pumping system in operation and implementation - and the lifespan of the system. It provides necessary flow according to system demand while allowing fault diagnosis and facilitating the maintenance of uninterrupted operation, thus enabling engineers to maximise system efficiency. The software references low and high
set point and run time requirements and the lead and lag pumps are cycled on and off based on motor run times. In contrast to alternative software solutions, WEG’s Pump Genius software monitors the operating hours of all the pumps in the system, adding and subtracting pumps as demand changes without the need for setting a cycle timer. This ensures equal
pump run times without supervision. A further key feature is the ability to have a floating master and slave rather than fixed master and slave pumps found in traditional systems. Pump Genius automatically senses if
the master is not responding because of sensor loss or additional fault conditions and assigns another pump as the master, maintaining operational continuity at all times during the process.
SEAMLESS TRANSITION Transition between master drives is seamless without disruption to the process so engineers can be confident that their system is operating reliably and efficiently. The CFW-11 variable speed drive with Pump Genius software monitors and alarms system, motor and drive faults which will alert the operator to a potential problem. The drives are available in sizes from 1.1
to 370 kW and include proven user friendly graphic key pad HMI with large character graphics and read out. In addition, all CFW-11’s have
intelligent thermal management features that provide automatic cooling to the internal components of the drive, ensuring they provide reliable operation. “Our pump control software is making
a real difference to the efficiency of systems whether composed of single or parallel pumps,” says product manager for automation and low voltage motors
Pump Genius software works with the CF11 drive to control pumping system processes
Daniel Griffiths. “Our customers are able to control pumping systems simply, allowing elimination of costly control panels, reduced maintenance and installation costs and energy requirements with increased productivity.

SINGLE SUPPORT CART FOR SCREEN CHANGER AND GEAR PUMP
A concept that combines screen changer and gear pump on a single movable cart simplifies their deployment in an extrusion line, takes up less floor space and provides easy access for replacement of filter media, has been introduced by Nordson KREYENBORG. This concept can be
applied for equipment custom designed by Nordson for other companies including extrusion processors, compounders and recyclers, replacing the standard configuration involving separate carts. The single cart is mounted on fixed casters that permit transverse-direction movement into and out of the extrusion line while precisely aligned movement in the extrusion direction is provided by rails installed on the floor. At the same time, linear guides on the cart permit independent extrusion- direction movement of the gear pump and screen changer. The rate of coolant flow is adjustable and the coolant may be either air
or de-mineralised water. Customers are asked to specify the coolant in advance so that the gear pump can be designed for optimal performance. If the material to be processed is shear-sensitive, Nordson recommends its Type 03 gear pump to minimise residence time.
