vacuum pump has me confused!!!!!!!!!!!!!!!

[philkasza]

We always could hear an air leak on our releaser when it was leaking but we had the pump in another building so the noise from the pump was not drowning out the vac leak noise. If it is a great big leak you may not be able to hear it. If you have valves for all your mainlines coming into the manifold, check and make sure they are all operating correctly. I've had valves break so that when I would turn the handle it would not close. I have never heard of vac pumps pushing air, they either pull vac or get wore out and pull less and less vac.

If you are getting vacuum without the releaser and then no vacuum with releaser it has to be the releaser.

Is the releaser a cdl horizontal with the sliding gate valve for continuous vac? If so, the seals in the sliding gate valve are probably shot.

yes its a cdl horizontal and i replaced those gaskets and the dump door gasket i've sealed off the upper chamber from the lower one with tape and only get 5hgs i used shaving cream to check for leaks thinking it would pull the shaving cream in where it was leaking but found nothing i will post pics in awhile first i have to change a flat tire on my truck then i will get pics maybe that will help everyone out a little more. Bad start to a good day already but its snowing out lol If there was another sugaring maker close to me that was willing i would hook it up to there pump to check releaser but theres not so i will get another pump and if no different i will have two pump and get releasers for them

I had a similar problem last year with my brand new releaser. What happened on mine was when the vacuum pump was turned on the vacuum would suck the cheap plastic shield inside the releaser and seal up the 3 inch hole stopping all vacuum from entering the releaser. I had to take this shield out and replace it with a thicker shield that would not bend. The better quality releasers have a thicker shield and white plastic bushings to keep the shield about 3 inches away from the hole. This might be what's happening to you.

it worked fine mid season last year then i stop being able to get vac to releaser. I thought pump was junk but me being me tried it this season to see what when wrong since i got mad last year with it and ran just gravity when it happened. Like i note proior (sp) i will get pics in a while and show everyone when running it was pulling 22.5 to 23 hgs at the releaser
