In the port city of Yeosu in South Korea, pump optimisation specialist Riventa has created significant financial savings at a worldwide tyre manufacturer’s water pumping plant, together with an annual vitality discount of 13%.

For a pressurised system that circulates cooling water for synthetic rubber processing, Riventa utilised its FREEFLOW know-how and Green Pump Index (GPX) benchmarking system to simultaneously monitor 5 pumps. For 150 hours, system strain was measured, together with circulate price and head mixtures to pinpoint how effectively the pumps might meet the various demands of the system.
Included within the tyre manufacturer’s goals was the want to handle stress aims for the system, which have been operating at 4.5 kg/cm2, in comparability with the contractual minimal supply stress of three.8 kg/cm2. Although pressure gauge 10 bar had the same casing, two of the impellers had been significantly totally different and Riventa found that by trimming the diameter of three pumps by 3.5%, an 11% reduction in stress could be achieved.
By totally understanding the operation of the system and how the pumps interacted with it, Riventa have been also in a place to calculate optimum performance and make potential GPX recommendations.
At pressure gauge octa of the challenge, the GPX index, which indicates the amount of power as a share that is efficiently transformed into helpful work by the drive, motor, pump and system, was 54, but after Riventa’s modifications, had improved to a GPX index of sixty four. So, of the 100% of electrical power consumed by the motor, just 54% of that energy was being efficiently converted into web hydraulic output energy.
