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

For a pressurised system that circulates cooling water for synthetic rubber processing, Riventa utilised its FREEFLOW technology and Green Pump Index (GPX) benchmarking system to simultaneously monitor five pumps. For a hundred and fifty hours, system pressure was measured, along with move fee and head combos to pinpoint how successfully the pumps might meet the various calls for of the system.
Included within the tyre manufacturer’s aims was the necessity to handle stress objectives for the system, which have been working at four.5 kg/cm2, in comparability with the contractual minimal supply strain of 3.eight kg/cm2. Although the 5 pumps had the identical casing, two of the impellers were considerably different and Riventa found that by trimming the diameter of three pumps by 3.5%, an 11% discount in strain would 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 suggestions.
At the beginning of the project, the GPX index, which signifies the quantity of energy as a share that’s efficiently converted into useful work by the drive, motor, pump and system, was fifty four, however after Riventa’s modifications, had improved to a GPX index of sixty four. So, of the one hundred pc of electrical power consumed by the motor, simply 54% of that power was being efficiently transformed into net hydraulic output power.
