In the port metropolis of Yeosu in South Korea, pump optimisation specialist Riventa has created significant savings at a global tyre manufacturer’s water pumping plant, including an annual energy reduction of 13%.

For a pressurised system that circulates cooling water for artificial rubber processing, Riventa utilised its FREEFLOW expertise and Green Pump Index (GPX) benchmarking system to simultaneously monitor 5 pumps. For 150 hours, system pressure was measured, together with circulate rate and head mixtures to pinpoint how effectively the pumps could meet the various calls for of the system.
Included within the tyre manufacturer’s objectives was the necessity to handle pressure goals for the system, which have been operating at 4.5 kg/cm2, in comparison with the contractual minimal provide stress of three.8 kg/cm2. Although the 5 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 3.5%, an 11% discount in pressure can be achieved.
By fully understanding nuova fima pressure gauge ราคา of the system and how the pumps interacted with it, Riventa have been additionally capable of calculate optimum performance and make potential GPX recommendations.
At the start of the project, the GPX index, which indicates the amount of power as a proportion that’s efficiently transformed into useful work by the drive, motor, pump and system, was 54, but after Riventa’s modifications, had improved to a GPX index of 64. So, of the 100 percent of electrical energy consumed by the motor, simply 54% of that power was being efficiently transformed into internet hydraulic output energy.
