In the port city of Yeosu in South Korea, pump optimisation specialist Riventa has created important savings at a worldwide tyre manufacturer’s water pumping plant, including an annual power reduction 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 one hundred fifty hours, system stress was measured, along with flow fee and head mixtures to pinpoint how successfully the pumps could meet the various demands of the system.
Included within the tyre manufacturer’s aims was the need to address stress aims for the system, which had been working at 4.5 kg/cm2, in comparison with the contractual minimal provide pressure of three.eight kg/cm2. Although the 5 pumps had the identical casing, two of the impellers were significantly totally different and Riventa discovered that by trimming the diameter of three pumps by 3.5%, an 11% discount in pressure would be achieved.
By absolutely understanding the operation of the system and the way the pumps interacted with it, Riventa have been additionally capable of calculate optimum efficiency and make potential GPX suggestions.
At the start of the venture, the GPX index, which signifies the quantity of energy as a proportion that is successfully transformed into useful work by the drive, motor, pump and system, was fifty four, but after Riventa’s modifications, had improved to a GPX index of sixty four. So, of เกจวัดแรง of electrical energy consumed by the motor, simply 54% of that power was being efficiently transformed into internet hydraulic output power.
