Question on the difference between a couple different dairy vacuum pumps

[miller maple]

I have a couple options on 3 different vacuum pumps my grampa has a sp22 and a universal massport and 2 delaval model 75 pumps what is my best option to use the most reliable one 590959105911

Don't bother with the SP-22, but I would be happy to buy it from you...

I am a huge fan of the SP-11s and SP-22s, but having said that, I have never run any of the other pumps. Love the simplicity and durability of the SPs- they can suck in sap when your moisture trap fails and with a little TLC, be back pulling vac in an hour...

If you do not use the SP-22, I honestly would buy it off you or your grandpa if you are interested in selling it.

Haha ok what size motor do you run on your 22 I'm not sure witch pump I'm gonna use yet but I think I think I'm gonna keep the other for back up. But if I end up selling it I will give you first chance

I believe the original electric motor on my sp-22 is 1.6 hp. Mine worked very well until the shaft on the motor broke off right behind the output bearing.:o There are days I wonder if it worked just as well as the 3hp Atlantic water cooled I replaced it with.:rolleyes:

The Massport will give the most CFM's at 18" of vacuum. My folks dairy could milk with 4 milking machines at the same time with no loss of vac when a cow was to kick off a machine. I assume it is the newer of the three.

The SP-22's are awesome. We run 2 of them at 20" all season long with no problems. Both have sucked sap once or twice with no ill effects once the oil is drained, replaced, run, drained and replaced again.

witch pump is gowing to use the least amount of energey

[ennismaple]

Thi past year was probably the worst example - but one of our SP-22's ran non-stop for the better part of our 11-day season and I estimate it used $25 of electricity. I forget the exact number of kWh.

I see that you have 600 taps listed in your signature. If so the SP 22 will be a perfect match. My system was tight enough so that i was able to maintain 26" of vacuum for most of the season.

yesterday i got the red massport vacuum pump gowin i had it hooked up to my releaser and my vac gauge was reading 28 pounds of vaccum

[tuckermtn]

just clarifying- it should be reading "inches of mercury", or inches of Hg. and its "-" negative inches. Max in regular environment on earth is -29 inches of Hg.

Its a good sign that it was reading -28, but it will likely be quite a bit lower when you hook up your releaser to your lines. The key to how many inches your releaser will read is how tight (leak-free) your tubing system is and how cool you can keep your pump.

sounds like the massport is going to be a good running pump- so i guess you won't be needing the SP-22. Sorry, couldn't resist....

[miller maple]

haha you want that sp-22 really bad, what would you give for it

[tuckermtn]

PM sent- thanks

Millermaple...good choice. Be sure to add a regulator to the Massport and let her run around 20" on the gauge at the pump. If your system is tight you should have pretty much the same reading at your releaser gauge. The Massport will treat you well!

have a question on my massport vacuum pump. so we got electric to the sugar house this year and i am planing on using the masport this year, we got it all set up and were having trouble with the oiler not working corectly was wondering if it would work to run a line directly into the vacuum line and have it suck oil through the pump. it dosent have a oil reclaimer but we did put and exhaust on it and put a down pipe on it to catch oil i was thinking i could run a line from the bottom of that oil catch back into the vacuum line would that work to keep the pump oiled and cooler.

You want the oil going in thru the bearings. Thru Graingers you can get replacement oilers, or McMaster Carr. You want at least 5 or 6 drips of oil a minute
