Riventa pump system optimisation reduces energy costs

In the port metropolis of Yeosu in South Korea, pump optimisation specialist Riventa has created vital 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 synthetic rubber processing, Riventa utilised its FREEFLOW expertise and Green Pump Index (GPX) benchmarking system to concurrently monitor five pumps. For pressure gauge and fifty hours, system strain was measured, together with circulate price and head combinations to pinpoint how effectively the pumps could meet the various demands of the system.
Included within the tyre manufacturer’s objectives was the necessity to tackle stress objectives for the system, which had been working at four.5 kg/cm2, in comparability with the contractual minimal provide stress of three.eight kg/cm2. Although the five pumps had the same casing, two of the impellers have been significantly completely different and Riventa found that by trimming the diameter of three pumps by three.5%, an 11% discount in stress can be achieved.
By totally understanding the operation of the system and the way the pumps interacted with it, Riventa were also able to calculate optimum efficiency and make potential GPX suggestions.
At the start of the project, the GPX index, which signifies the quantity of power as a percentage that is efficiently transformed 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 the one hundred pc of electrical energy consumed by the motor, just 54% of that energy was being successfully converted into net hydraulic output energy.
