In the port metropolis of Yeosu in South Korea, pump optimisation specialist Riventa has created important savings at a world 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 expertise and Green Pump Index (GPX) benchmarking system to simultaneously monitor 5 pumps. For 150 hours, system strain was measured, along with circulate rate and head combinations to pinpoint how successfully the pumps could meet the various calls for of the system.
Included in the tyre manufacturer’s aims was the necessity to handle stress aims for the system, which had been working at four.5 kg/cm2, compared to the contractual minimum supply strain of three.8 kg/cm2. Although the five pumps had the same casing, two of the impellers were considerably totally different and Riventa found that by trimming the diameter of three pumps by 3.5%, an 11% reduction in pressure can be achieved.
By fully understanding the operation of the system and how the pumps interacted with it, Riventa had been additionally in a place to calculate optimum performance and make potential GPX recommendations.
At spmk700 of the venture, the GPX index, which indicates the quantity of energy as a share that is efficiently converted 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 64. So, of the 100% of electrical power consumed by the motor, just 54% of that energy was being efficiently transformed into web hydraulic output energy.
