In the market for a new pump. Looking for something that's going to be reliable for as long as possible. Don't mind paying what I have to. Suggestion's?

Dude if you do a search you will find numerous posts on this subject. You should search on the hows and whys of vacuum also and you will see that bigger isn't always better. I have had JB, Yellow Jacket and Robin Air and all have worked well. Would say the first two I liked better than the later. I now own a JB platinum and a yellow Jacket and use them both we great success.
Quite a few of the guys I work with have Robinair Cooltech pumps model 15600. We've all had pretty good luck with them.
Changing the oil in the pump, and having a good vacuum setup are just as important as the quality of the pump. I usually use 1/2" and 3/8" hoses along with a vacuum manifold and core removers. It really speeds things up.

I read the first 4 pages looking for a thread on this before posting. Sorry to be annoying with redundant subject matter. My old Robinair has just had it. Was thinking about going with this...

IMO..this is a much better pump. My first one lasted 12 years. I went through 2 JB's in three years. Went back to this.

The motor has a heatsink and a fan, and you dont have to worry about a start cap/relay burning out.

You must be getting paid pretty good, those things are expensive, let alone two.Two Appion's are a weeks pay
I could buy multiple Robinair's for what they want for one TEZ8

I have the jb 10cfm and the robinair 5cfm. I use the robinair for back up or if I have to leave a pump running all night somewhere. I think I would look at appion before buying a new pump.
And probably then some.

It would be nice is someone came out with a 120v/277v pump.
That might require some smart circuitry to keep someone from plugging in or switching the voltage and burning it up. I like the idea though.

It's not always about the vaccume pump ... Your hoses are almost more important that they are not leaky

i like the paint coating over the braze connections. i usually uses a grey zinc coating. to reduce the steel from rusting i have regular blue and grey spray paint for the dryers. a could reason for doing it as well is so a tech cant go behind you and tamper with your braze connection and say it was leaking. fill me in on your reason your painting over the things. what made you do it? just curious
Its to keep them from rusting. Technically if we're doing a pm, and we see a rusty drier, we're supposed to sand it down and paint it.
I usually put some tape over the copper ends, so I don't get paint all over the copper. Makes it easier if you have to unsweat it. Looks like I forgot to do that this time.

im quite happy with my rothenburger 6.0
You're not supposed to unbraze a drier since it would release some of the moisture it has collected. Use tubing cutters whenever possible.Its to keep them from rusting. Technically if we're doing a pm, and we see a rusty drier, we're supposed to sand it down and paint it.

I have a cheap Master Cool single stage 6 CFM. I could not believe how fast it pulls down. I've seen it pull down a 20 ton package unit to 600 microns in less than 2 hours with 1/4 inch hoses and the schraders in.
