In the port metropolis of Yeosu in South Korea, pump optimisation specialist Riventa has created important financial savings at a global tyre manufacturer’s water pumping plant, including an annual energy 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 5 pumps. For one hundred fifty hours, system stress was measured, along with flow price and head combos to pinpoint how effectively the pumps might meet the varying calls for of the system.
Included in the tyre manufacturer’s objectives was the need to tackle strain aims for the system, which had been working at 4.5 kg/cm2, in comparability with the contractual minimal provide pressure of three.eight kg/cm2. Although the 5 pumps had the same casing, two of the impellers were significantly different and Riventa discovered that by trimming the diameter of three pumps by three.5%, an 11% discount in pressure can be achieved.
By fully understanding the operation of the system and the way the pumps interacted with it, Riventa have been also able to calculate optimum efficiency and make potential GPX recommendations.
At the start of the project, the GPX index, which signifies the quantity of energy as a percentage that is 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 Forgotten of electrical energy consumed by the motor, just 54% of that power was being successfully converted into web hydraulic output power.
