In the port city of Yeosu in South Korea, pump optimisation specialist Riventa has created significant financial savings at a world tyre manufacturer’s water pumping plant, together with an annual energy reduction 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 a hundred and fifty hours, system pressure was measured, along with circulate price and head mixtures to pinpoint how successfully the pumps might meet the various demands of the system.
Included in the tyre manufacturer’s aims was the necessity to handle pressure aims for the system, which had been working at four.5 kg/cm2, in comparison with the contractual minimum provide pressure of 3.eight kg/cm2. Although the five pumps had the identical casing, two of the impellers have been considerably completely different and Riventa found that by trimming the diameter of three pumps by three.5%, an 11% reduction in pressure could be achieved.
By totally understanding the operation of the system and how the pumps interacted with it, Riventa have been additionally in a place to calculate optimum efficiency and make potential GPX suggestions.
At เกจวัดแรงอัดกระบอกสูบ of the challenge, the GPX index, which signifies the amount of power as a percentage that’s successfully converted into helpful 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 100 percent of electrical power consumed by the motor, simply 54% of that power was being successfully transformed into web hydraulic output power.
