Finally a Vac Pump for me :D

[Gray Mole]

Maybe a common thing to you guys, but I've finally found one. I could have bought a cheapie new one for about the same but I saw this and got it for a decent price, at least it's decent around here.

Built in vac guage and isolation valving.

I think she's beautiful, though the wife will NOT be happy I'm sure :slapass:

Ah well, should do the job in style, and should be with me this week.

Awesome bro :woot: - that will come in handy.. She is a beauty. :slobber: :slobber:

[placebo]

Congrats my friend... very nice Yellow Jacket pump you got yourself. Also, she looks to be in an excellent condition for a used one.... Good deal! :D :clap:

How many CFM and may I ask how much you paid for it?

[Gray Mole]

To be honest I'm not sure of the cfm on it. It's not that critical to me as long as it pulls nice, the systems I'm gonna play with won't have much to move.

It looks like 48L/min and that's 1.7cfm which may or may not be right. I should get the model number emailed back to me soon. Most of these are rated for 15 micron and that's enough to boil just about any moisture off without heating anything up. That'll do me just fine :D

If it's a higher spec unit, great, but even their basic units are just what I'm after.

Price, well I'll just have to leave you wondering lol I just never felt right posting that sorta detail. It's kinda like telling you how old I am ;)

It was as much as I could get a cheapo single stage pump for new, but I'd rather buy a good used one than a cheap new one, you know? Long as it's in nice shape and this one looks great.

Cheers

That's what I always say when I got burned.. :D

Hey I got used to getting roasted the minute I stepped foot in the UK :fact:

£115 delivered to my door.

Not a bad price I think, or at least I hope lol I couldn't get anything that looked good for that much in the UK. I envy the US guys for that, so much more in the used HVAC equipment there.

There, and I'm 34 years old too :p:

:lol:

Congratz man. Looks like a darn nice unit. Should suck pretty good lol.

[jinu117]

Since I've been searching, I think it probably is 3cfm model with 1/2 hp or 1/3 hp if it pulls 15 micron minimum :) Sounds like you got really good one there :)

[jinu117]

Heh quick search on e-bay shows this... (US one)
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7530138989&category=66999

4 cfm, 1/3 hp. Unless my eye is lying something it seems like identical vacuum sans yours looks pristine. Which is even better :)

Hmmm I found out they all look same except 1.5cfm one. So it must be 4cfm + :P

[wdrzal]

thats either a 1.5, 4 or 6 cfm, if the electric motor is 1/6 hp its 1.5 cfm---1/3 hp its 4 cfm if its 1/2hp its 6cfm. That will last you a lifetime, thats a very well made pump.Even 1.5 cfm is plenty , more important than the cfm is the micron rating, yellow jackets are 15 microns.their web site is www.yellowjacket.com

[Gray Mole]

:)

I had a look at their website, and from what I could see the shape of it looks like the 4-6 cfm units, but it's not the newer model, so I'll only know when it's here.

I hope it lasts well, and for what I'm doing, and the amount of use it'll get it should last well. I like to make sure the maintenance is done regularly so it should be a happy machine :p:

As you say, Walt, i'ts mainly the vac it'll pull that's the most important thing, and I liked the look of the that from the start. I might just have to boil some ice cubes just to see it happen :rolleyes: :D

Thanks for the feedback guys :) nice to know I made a good choice.

More importantly, now I can get on with some projects that I've been waiting on :toast:

Congrats mate I am just looking at my first stage frosting up I scored a nice condenser this weekend but now I will have to wait till I get back from hols to play plus I think i need bigger compressors

[Gray Mole]

I've heard about your Cascade mini project and it sounds cool. It's a good practice run, though you'll definitely need more capacity on the high stage from the sounds of it, you're further along that I am lol

I've got the tail end of the week pretty free, so I'll get the last of what I need for teh high stage on mine, and hopefully have a working first stage by the weekend :D

The Vac pump was pretty much the last big tool I needed to get things rolling, other than gas I suppose, which is just as much or more :rolleyes:

Gray

[fatty]

Well my mini cascade test toy whatever you want to call it will do -60 idle still trying to get it stable under load lol

[s7e9h3n]

Sweet pump. Yours looks like the current model of mine:

I picked this one up for ~$140 shipped and she works like a charm. These are great pumps :toast:

[Gray Mole]

Sweet. Sounds like I made a good choice, these are a lot more popular than I thought!

Just seemed like it had a few more options than teh cheaper ones, and I knew they had a good rep. It was the Vac guage that got me, anything for those lil extra's. :woot:

Actually mine's not even the current model, they've all had a facelift from what I can see on their site, but at that price, I feel I did ok now, seeing as it's a little newer. I've found Robinair seems to have 'the name' here in the UK, and Yellow Jacket seems a little less known. Good thing for me I guess :D It's still far more than you guys in the US could probably pick one up for though.

I plan to play with this stuff for a very long time, maybe it'll outlive me lol considering how unhealthy my lifestyle is, that shouldn't be too long anyway :rolleyes:

I was thinking the same about the vacuum gauge when I first got mine, but sorry to dissapoint, that thing is almost of no use whatsoever, especially if you own a manifold set. What happens is that as soon as you flip the pump on and it starts pulling a vac, the needle just basically goes all the way to the end and just flutters there if the system is relatively leak-proof. IMO, your manifold gauge is much more useful during an evac than the one on the pump. Ideally, though, I'd own a micron gauge for evauating........ ;)

[Gray Mole]

Shame, I was hoping the guage would be more useful.

Ah well, it's easy enough to plumb in a permanent micron guage to the Vac pump.

I've never found manifold's to be terribly great for reading a Vac either, and for initial leak testing I'd like something that's going to work.

I figured the guage would read low enough that a leak would be somwhat obvious, but if it doesn't work for you, it's not going to work for me either lol

I'll start digging around for a micron guage for it then too :)

[pazza316]

Gray where did you get that pump from in the UK?

[gkiing]

I have the same pump (6cfm one) , it works great!

[stockhatch]

I have the same one too. This pump really sucks! I love it :D http://img.photobucket.com/albums/v46/stockhatch/pump_2.jpg

[s7e9h3n]

Oh, one thing I forgot to ask...what is the blank-off valve used for exactly? Mine doesn't have one, but all new model vacuum pumps seem to have that feature. However, I do own a 4-valve manifold so I'm assuming that closing the valve connected to the vacuum line does the same thing?

[Gray Mole]

I'd assumed the cut off valve was just to isolate the system from the pump so you could rule out any leakage from the pump internals, but I'm not really sure.

My new pump arrived today :D they even did half of the oil change for me :rolleyes: laying it on the side of the box (even with a HUGE 'this side up' sticker on every side) the oil is all drained away. The plug got smashed as well so I'll have to replace that too, but in the UK you always put a new plug on things.

I'm picking up some oil tomorrow so I'll test it then. Was planning on an oil change first thing, but I'd have tested it anyway.

It's MASSIVE! Having worked in the Automotive sector I'm used to Vac pumps and air con, but this is the biggest Vac pump I've ever seen.

I found the spec, and on the dual voltage motors they run slightly slower on the 50hz here, as opposed to 60hz in the US, so instead of being a 57L/M or 2cfm pump, it's a 48L/M or 1.7cfm pump cos the motor drives the pump a little slower.

No big deal, it's in the 2/4/6/8 cfm range, so is the larger casting and same motor as those, with the smallest pump for that range.

Looks great though, and should work well :)
