Hello,
I recently purchased the pieces parts for a large Delta 50-904 dust collector. it has a 7.5 hp 3 phase motor, a damaged 16 inch impeller with about 5 inch blades (see attached pictures), and a large cyclone on a substantial stand. The motor has a 1 1/8 inch shaft. The previous owner struggled to remove the impeller from the shaft in an attempt to install it on a single phase motor, and cracked it during his removal process.
I have been given quotes totaling about $600 to have the impeller weld-repaired and re-balanced. However, given the very large forces on the impeller, especially during startup, I am concerned that it might fail and create a very dangerous condition in my shop while destroying the cyclone separator, etc. Do you think this concern is warranted?
Alternatively, I have tried to find a suitable replacement impeller. Some parts shops have listed prices from $1250 through about $3600, all prices I consider to be unreasonably high. I have tried several other sources and have not found success finding even a somewhat smaller diameter impeller with a 1 1/8 inch shaft bore.
I welcome all thoughts and recommendations on how I might be able to get this large dust collector working again!
Thank you for your help!!
