A major U.S. sugar producer has several hundred pumps throughout the plant. These pumps are either using packing, which requires constant maintenance or using mechanical seals, which require a water supply to cool and flush it. In the latter instance, the water is usually either returned to a seal water tank or dumped to drain. Any water that ends up on the floor or in a drain finds its way back to process and must be evaporated (large cost) or sent to wastewater (even larger cost). Because of this, any unnecessary water flow that can be cut from the process is beneficial.
CHALLENGES
- This plant faced several challenges prior to its adoption of EcoFlow valves:
- The plant could not use mechanical seals on their pumps due to the large water demand and up-front expense of a closed recirculation system.
- Packing was used in all pumps instead of double mechanical seals, causing leaks and constant maintenance.
- Expensive seals were damaged every year due to accidental dry running.
HOW OUR ECOFLOW VALVES HELPED
ThermOmegaTech® EcoFlow valves were placed on the seal water outlet of their pumps’ double mechanical seals to control the seal water temperature…
