The objective of this RFQ is to give the required information for procuring two new shaft seal water filters for Mayo Hydro Units MBH1 and MBH2.
The scope of work is to replace the existing shaft seal water filtration systems and control panels. Two units: MBH1 and MBH2
Refer to Appendix 5 for the schematics and general arrangement:
Water is taken from the penstock through a 100mm pipe, then it passes through a cooling water skid where pressure is reduced. A part of this water is sent to the shaft seal filter and then to the shaft seal.
It shall be noted that the existing shaft seal filter’s location is in the oil lube skid. New shaft seal filter is located at a different place. See details further in the document.
The preferred brand for instruments, sensors and transducers is IFM®. Alternatively, similar equipment shall be used upon the client's approval.
The piping/tubing coming from the cooling water skid or exiting to the shaft seal is out of scope. Information about the current piping length is given as a reference for design purposes.
The piping required for the filter operation (by-pass piping, flushing, etc.) and maintenance valves shall be included in the scope of supply.
The Contractor must provide the drawings, the piping and instrumentation diagrams, the electrical and wiring diagrams, the maintenance and operation manuals, the specification documents, and any other relevant document to the client with the product.
All electrical installations shall comply with the Canadian Electrical Code (CSA C22).
See the Shaft Seal Filtration Unit - Purchasing Specification in Appendix 5 for more information.
