Vacuum Pumps This Pump Packs Brains and Brawn
Better make it double: Edwards Vacuum equips its new range of liquid ring pumps with not just one but two variable speed drives (VSD).
While the main VSD matches the speed of the pump to vacuum level by adjusting its speed, the second VSD regulates the water flow through the centrifugal pump according to the operating conditions to avoid risks of cavitation. A patented algorithm always maintains a perfect harmony between the two VSD’s ensuring optimal performance, the manufacturer ensures.
The integrated Air logic controller not only enables the monitoring of important features and parameters of the new Elri line of liquid ring pump but also offers the option of set-point control. This allows users to have a vacuum pump that matches the process demand saving energy. Made for applications which are wet, humid as well as corrosive, the Elri-series comes in pumping capacity 750-1050 m3/hr to covers a wide range of applications in the central vacuum, pharmaceutical , plastics, conveying and food applications.
