The search for a proper recovery pump..

[Gray Wolf]

Aaaaand, Bhogart just went kaboom and is presenting us with a dual stage recovery pump. Pushes 2cfm as opposed to the CMEP-OL's 1.25 cfm (which they also sell, both $2800).

I'm hoping someone from BHOGART chimes in real soon with more serious details and pictures, as they are advertising the pump on their website and Instagram.

Did anyone know about this one coming?

I knew about the 2 hp OMEP-OL 6000 standing in the wings, even as we were trying out the CMEP-OL,but the 6000 was made for refrigerant recovery to 260 psi, which exceeds our needs and thus doesn't use its horsepower most effectively.

Rather than high pressure, I am more impressed with the VaporHawg's output volume, which uses a robust tried and proven US made pump, with the same 2 horsepower to produce 6 cfm and up to 160 psi before shutting off from an over pressure switch.

Hee, hee, hee, snicker, snark, snort, let's git it on!!!!!! Bigger is better, and too much, is almost enough.

Man I'm excited for that VaporHawg! I've already contacted James and am on the list!

Hey There, we're very excited about this new pump! More photos and details are being written up this week, if the community has any specific questions they would like answered please ask away and we'll cover them in our response.

Here's a few close up photos. Marathon motor, KNF pump. American and German made.

I'm very interested in the diaphragm pump would live to hear some real lab experience.

They are on back order for 2 weeks. .. this odds info u got today. ...recovery time is 40 min on 10lb extractor with their heat exchanger. ... also I was told that it can handle low vac very well. .. if you are interested put deposit down in 1 week. ... their going to go quick

 

[BigJohnny]

Hee, hee, hee, thangs just keep on getting better for us'n extractors!

Not only has Haskel provided our market with kick ass NEMA 7 Class 1, Div 1, pneumatic refrigerant recovery pumps, but Pharmgold has completed prototype testing and ordered parts for their first pilot run of their NEMA 7 Class 1, Div 1, two horsepower V-twin VaporHawg.

About 6 scfm free air, and capable of both single or double stage, depending on the end pressures desired. It also readily pulls down to -29.3" Hg single stage.

For those of ya'll admiring nice jugs, check out the size of VaporHawg's big bore pump and check out the size of the piston guide sleeves.

More as things progress.

I think I just peed a little....... when can we expect to this? and where do they come from? nothing comes up on google

[email protected] is who I would contact. A new company, that doesn't have their site up yet, but I do know they have folks working on it.

I'm doing 11# in 30-40 mins with one cmep ol and snow on a terp coil upgrading everything to 3/8 and dual cmeps this week, I'm more interested in the reliability and safety of the diaphragm. I was in bhogart this afternoon and talked with them about it and checked out the heat exchanger, seems like a viable option nit really any faster than I'm doing now.

What's the displacement of this pump and max. output pressure? Will it start under max. rated pressure?

Thanx.

I got an email back from them about the vaporhawg, and they say it's 6CFM and the price will probably be about $9999 ..... yes $9999 .... wow.

 

[furrywall11]

Probably already been asked but...
Has anyone had any tests done for industrial lubricants in the concentrates that are made using the CMEP-OL recovery pumps?

 

[Old Gold]

I forget who (Pure777Extracts?), but someone mentioned Analyticial360 claimed there was no contamination in their product. I have not been able to send to a lab recently, but solvent flushes are clean and have no smell. Nothing funky from the only recent test results either, but I doubt the person who sent it out for testing mentioned anything about lubricant a he doesn't have any knowledge of pumps, closed Loops, etc, as much as I try to educate about my process.

 

[furrywall11]

Hmm well, the lubricants possibly making their way all at once, or in small amounts over time, into the concentrate seems to be the only major problem with the pump. This, however, comes from my very modest knowledge of recovery pumps. We should all collaborate and see if we can get these tests done asap!

I say we collaborate and do up this crankcase modification. If you've got a few Benjamin's to spare (and I do mean a literal few), we could get one of these pumps to an individual who can show us how it's done. Message me if you're really interested.

Like I said previously, I haven't seen one in person but I don't really see a reason why you couldn't just drill a hole in the crankcase to vent it. Just gotta find the right spot to drill it.

 

[Old Gold]

Yeah I guess so..
That easy, huh? Any hole would remove the possibility of a vacuum in there, but diameter (thus, air flow as well):in relation to it's volume probably plays a role in how deep the pump is able to pull into vacuum.

I think the problem is expansion due to temp, so as the pump heats up so does the air in the crankcase, with no place to go it has to blow by the seals.

drill a small hole to allow for that expansion/contraction and it should prevent crank case grease from blowing by the piston seals and getting into the butane stream.

the CPS TR21's have such a hole in the bottom of the crankcase, presumably for this very reason.

 

[jswick93]

I think whether or not your meds are contaminated depends on the specific CMEP-OL you have, rather than the model itself. I can say for certain that if I were making product with mine it would be contaminated. The grease inside my crankcase is bad enough that it's getting past the pistol seals. I spoke with someone who works on these, who said that it's a bigger problem with the first of these that came out, and that the newest machines have bearings which are lubricated with ptfe instead of the grease/graphite used on the earlier models. I don't know about this, but this is what I was told. He says that he hasn't seen a problem after a rebuild and clean out with those newer bearings. Anyone know anything about this?

 

[Old Gold]

Very interesting note, and it does make sense.We got ours here right around the time Ecogreen started selling "refurbished" pumps as well. The one we bought was new. I forgot to ask what the difference was, just made sure the one they sent us was in fact a new piece.

I really need to take the fucker apart to the bones, for the geek of me, if anything. But for the knowledge of the community of course. I can't seem to find a day's break, let alone longer, for stripping and rebuilding. Soon enough, I vowed...

Then again, I THINK we hit contamination at one point after a week or two of use.
How do you "lubricate" with PTFE?
