Hey there dose anyone have experience with a mvp 150psi recovery pump?? I started in a new lab that has one but when I tried to use it, it seemed to just blow gas out of the back of it and not recover it. I had to switch to a cmep.
Yeah, post a photo of how you have it set up including all hoses and connections from your recovery vessel to your sieve, pump, condenser, and solvent tank. If everything is lined correctly then you need to identify where your system is leaking, so you can fix the problem. A gas sniffer would be a useful tool for that

How is anybody supposed to decipher the plumbing of your pump from that?!?
get the MVP out of the booth and test it. It should work just like an air compressor

So not currently plumbed…fair enough.
When you say “out the back” was there a hose connected to the outlet (the JIC in back that we can’t see in that picture…)?!?
I don’t see a test procedure listed here Support — MASTER VAPOR PUMPS
but it may be in one of those videos, or you could ask them.
I assume you’re feeding your CO2 from a larger bottle? And have two inlets so you can switch tanks. (Yeah I know, you’re not the one who did that, so wtf would you know. It’s your problem now, so let’s figure it out…)
You should be able to test it simply by hooking the outlet to any vessel capable of taking 150psi. I’d recommend one with a gauge and a prv. Don’t use one that has solvent in it already.
Leave inlet open. Make yourself some compressed air. Use soapy water to ID leaks.

(Nope, second port is a vent. Just now RTFM 
)
Which is from the MVP 60 manual, but still relevant. If someone decided you needed bigger, it may be the failed to diagnose a busted diaphragm.
You have read the fine manual yes?

It looks like something threaded went into this hole I pulled it so I could get a run done now I have to figure out what’s wrong. I do charge it with 150psi before I start it.
Live resin
Fresh froze
Does that mean you failed to RTFM?
Definitely read the fucking manual lol at least what was available at the lab I don’t think it was a full manual I’m looking for a pdf of an online copy of it.

I’ve called mvp a grip of times no call back and no answer for about a week I even went through the list of venders that they had on there website and called all of them I talked to two people that answered out of the whole list and they weren’t really sure about the mvp 150psi pump they bolth said I should just run passively

Support in the cannabis industry… woof.
Yeah, the only manual I found in the 45seconds I allotted to the task was the one linked above.
Not sure we still have our MVP, but reasonably sure that hole is supposed to have a plug in it. Can’t see how you’re gonna pressurize the center section without said plug.
Happy to take a look for/at ours on Monday.
Have you tried emailing them?

I appreciate you Brotherman and it was working the first two times I ran but I’m pretty sure your right a plug is saposed to be in there I’m waiting on a phone call back from a guy that rebuilds them should have it figured out. Do you run the co2 continuously through the run or just to charge it?? I used it to clear air from lines then charge but then I turn the co2 off the “manual” that was in the lab when I started didn’t really explain that part.
You tell me…
From the manual I linked:
Note: I would expect this to be unsuccessful with the unplugged port on back of your pump.

Took another 30 seconds to find the MVP-150 fine manual… https://www.graco.com/content/dam/mvp/tech-documents/manuals/3A6/3A6339/3A6339EN-B.pdf
Is this what you have in lab?
Should the CO2 be on while running?!?
…then I spent several min tracking down this one: https://www.graco.com/content/dam/mvp/tech-documents/manuals/3A6/3A6340/3A6340EN-D.pdf
Which might help you figure what you’re missing.

CO2 should be used to prime the pump. Leave the exhaust valve closed while you add the 150psi. Omce the 150 psi reads out on the gauge you close the inlet. When you are done for the day. Bleed the CO2 by opening the exhaust valve.
Edit: on the pictures the pump isn’t even plumbed to the closed loop. Im assuming thats just while you figure out the pronlem?

that is not how I read those instructions…
