In the port metropolis of Yeosu in South Korea, pump optimisation specialist Riventa has created important 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 artificial rubber processing, Riventa utilised its FREEFLOW technology and Green Pump Index (GPX) benchmarking system to concurrently monitor 5 pumps. For one hundred fifty hours, system strain was measured, together with circulate rate and head combos to pinpoint how successfully the pumps might meet the various calls for of the system.
Included in the tyre manufacturer’s aims was the want to handle stress goals for the system, which were operating at four.5 kg/cm2, compared to the contractual minimal provide pressure of three.8 kg/cm2. Although the five pumps had the identical casing, two of the impellers were considerably completely different and Riventa found that by trimming the diameter of three pumps by three.5%, an 11% reduction in stress can be achieved.
By totally understanding the operation of the system and the way the pumps interacted with it, Riventa had been additionally capable of calculate optimum performance and make potential GPX suggestions.
At the start of the challenge, the GPX index, which signifies the quantity of power as a percentage that’s successfully 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 64. So, of เกจวัดแรงดันไนโตรเจนราคา of electrical energy consumed by the motor, simply 54% of that power was being efficiently transformed into web hydraulic output energy.
