The Mill Creek Treatment Plant is experiencing cavitation where static pressure leads to the formation of small vapor-filled cavities. When this occurs and is introduced to high pressure, these cavities often collapse and create damaging shock waves. We have one pump that was destroyed by this phenomenon and others that are damaged. We’ve been looking for a solution to remedy this problem and discovered these eccentric reducers. We expect this reducer to help decrease cavitation within the RAS pumps. Reducing cavitation will lessen maintenance costs and help extend the life of the RAS pumps. It will also allow the pump to be more efficient. Increasing efficiency anywhere in the treatment process is beneficial to the entire process. If we do not implement a solution, we are facing additional maintenance and equipment costs prematurely. The primary objective of this RFI is to obtain information and potential sources that can provide the City with a Vaned Eccentric Reducer. The City is requesting information about how vendors produce Vaned Eccentric Reducers, the benefits of using their products, and how long it takes to obtain one.
