We have a 20hp Bekker Vacuum pump needs service, we are in Sacramento, CA. The authorized Bekker techs in the Bay Area say they are too busy to even come out. Does anyone know a Northern California roving service tech for vacuum pumps?
A source for used vacuum pumps?
I use searchtempest and do a search throughout the country for anything I want to purchase used.
Then use a shipping company (freighquotes.com works well ) to get it to your shop.
Becker can send you a pump (rental) until they can repair yours.
What's wrong with it ? Or, what is it not doing ?
There is a wave or ripple on the inside wall of the cylinder. We don't know if it's big enough to be a problem or not. Possibly from overheating - we'd built an enclosure around the vacuum pump to cut down on the sound and maybe there was not enough ventilation it appeared to be overheating. But don't know if that ripple was there before and no big deal, or if it's new and that is what is causing the vanes to break. Or maybe our guy was putting the new generic vanes in wrong. The proper Becker vanes are $4,000 and we'd bought generic. But maybe that is the problem also.
Trust but verify.
Very expensive to second guess or to get mis information. I have had them, you need to make sure they get greased, changed when out of spec and get any chips or shards out of the chamber.
I canít see how a you could have caused warping with that sound enclosure. Surely, you had supply and exhaust, right ?
I have seen what I think you are referring to in the housing. It happens with both vane style vacuum pumps and vane style compressors. What you are seeing is wear the cure is to replace the housing. This is why we only use roots or screw style pumps, they last longer.
