Since I'm new here I thought I should try and help, SK-6015 Piston Seal Rebuild Kit (Includes Piston Seals, Energizer O-ring, Wear Bands) is what you want. Be especially careful to mark how everything goes together (take pics, mark tubes that connect together, note the direction of the tab on the cylinder heads go so in and out go the right direction), and be especially careful of the copper tubes that connect it all together. Don't kink them. Test before you hook back up to your system. If you don't know what you are doing or are the least bit hesitant, send the machine out for service. PLEASE. You will need a torque wrench, screwdriver, wrenches, vacuum oil, razor knife, and some threadlock. I would recommend a camera, permanent marker, and a bowl for screws and bolts. Please be gentle in your criticism of my post, I'm new here. Hope I have helped.

The search for a proper recovery pump..
- Thread starter HighStateToke
- Start date
appion turned their back on the community so to speak, lets just try and avoid the same situation and avoid mentioning extractions for the time being. im in talks with their service unit and technical center now. once gray wolf works his magic with the data ive received we can make this happen for you guys
got some good info ill forward to you from the repair wizards
sorry i havent posted up much lately guys, i feel like smeagol in the cave with the precious, still compiling data of the quirks and upgrades to the beta unit to finalize the newest mk5-bravo-version3.1-vista-sasquatch osx-2.0
ps - the new sight glass, i recommend filing the edges of the face plate down cause its sharp and cut my finger to the bone while tightening a high pressure clamp.
the gast pump outlets T into a single line that runs through the liquid line on the 50# tank, the promax inlet is hooked up to the gas inlet of the 50# tank and the promax outlet goes to the 100# tank via heat exchanger.

The Gast service said that the Gast doesn't like inlet pressure, so I'm looking for a suitable demand regulator, so that the Gast has no pressure on it until it sucks.
We filed radius's on both the square edges and the hex headed bolts in the face. SS cut his hand on a square edge on the face and WW his knuckle on one of the hex headed bolts.
you can source stainless coils through most brewery website. They are used in jockey boxes. You can also source copper from home depot and coil it yourself, then put a couple compression fittings on the end. I've found its a great place to T two recovery pumps together. I recommend using ball valves as well to aid in clearing the line at the end of the day.
Go stainless i you can, IMO

heat exchanger?
heat exchanger?
Perma, Jockey Boxes and MT-69's seem to have an inherent flaw of not being gravity flow. Which means if its colder than your refrigerants condensing point it may/can/ does hold some liquid.When recovering refrigerant on an A/C system the MT-69 stays in cool H20 to avoid this but still help return times. So I would like to go with something that takes advantage of gravity and could supercool my return flow. I have some calls into the CO2 manufacturers about their(coil in coil) systems but these require a chiller. I like the idea of making my own out of copper but have you tested one to 400 PSI? Isn't hi pressure water bending necessary for kink free pressure rated. Input much appreciated.have you worked through these issues?
GW, It seems you may have tackled this exact design cost issue. I (just) saw a post you made on a twenty foot piece of SS you were bending into a heat exchanger and using a SS stock pot. How did that work out and what fittings did you use? Got pics?
Might you just bypass the Gast until the low side is low enough? Or have your separator vessel at 0C for Butane and -40'sC for Propane(at least initially) which would relieve the pressure.
And please people... I'm a Newb. There are prob a million of you with more practical than me. If I'm way out there or just obviously don't know of what I speak, explain so I learn.

Works slick. Sorry it is still dark out, so the picture taking is limited.
I welded couplings in the pot and insulated it with closed cell neoprene foam.
The butane comes in the side port and exits the bottom.
I used Hoke 90 degree el MNPT X compression fittings in the welded couplings, to attach the tubing.
The extra valve in the bottom is for draining the pot.

Beautiful
I can dig it, but would think another isolation situation would be better. I've always thought an orange igloo cooler, cheap and well insulated. Coil could go though the top and out through the bottom water thingy. D/I on the inside, and you golden. Don't know bro ... think I'd put more filter dryer's before the heat exchanger. See that big guy you got after it, lol. Anyways lookin good

Maybe a pot in an igloo cooler......
The K value for closed cell neoprene foam is about .3, which would give it an R value of about 3.3 btu/hr/ft2/inch thickness. They use it for wetsuits and you can always add layers.
An Igloo would have a better R value than our single layer, but we didn't use plastic, because we are planning to experiment with alcohol/dry ice baths. We welded in all the fittings, instead of using a bulkhead fitting with elastomer seals.
More drying capacity is no doubt a good thing, but it all adds system back pressure and lowers efficiency. We thought we would start with a nice sized single one with 1/2" ports and add if required.
As you allude, any water in the system before the heat exchanger, can condense out in the lines and freeze up at -70C.
Id never named a terpenator before, but there was only one i could think of, the most beautiful name in the wide world...
Ladies and gentlemen, Jenny is almost done. "We got a whole bunch of boats. Twelve Jenny's, a big ol' warehouse...."
JColtrane, you should come visit soon.

All of WolfWurx's turnkey systems get named by the owner before delivery and gets a name plaque. SS named this one "Jennny" after Forest Gump's boat fleet, all named Jenny.
The unit is ready for delivery, but we are still working on the hand scrawled name plate. Alas, no fonts are readily available in scrawl, so it is an artistic endeavor.
I'll post the pictures when the photographer returns them. We used a professional this time, with a green screen background, so we can change the background of the pictures at will.
A Mk IV and a V are different animals, starting with pot size, but I have no doubt that WolfWurx could help you mount your Mk IVB kit on a cart, if you contact WW.
You are welcome to a cart print, if you want to DIY, or WW can order you a cart built.
We have them fabricated from 304SS, by Insta Fab in Vancouver, WA, and have Multi Craft Plastics in Tigard, OR cut out the HDPE shelving.
Insta Fab has been around awhile and built some of my most exotic equipment before retirement.
WolfWurx is currently awaiting the Haskel pump, to start final assembly of a Mk IVB turnkey system for an east coast extractor, so should have an example in the shop for you to see and caress, if you promise to not get it all sticky.
Alas, WW already delivered the turnkey Mk VB, but there are a couple Mk VA2's being assembled, to ogle for comparison.

How do you think a KNF UN726FTP would perform on on MKiiia in front of an a5 with two #50 tanks? I would eventually like to upgrade to the auto pressure switch if I did this but it would be manual at first.
I know its not the ideal pump, but I have an opportunity to scoop one up for next to nothing. Your guys thoughts?
I'll include a link to the manual but I'm not sure if it is allowed.
Some excerpts:
Model - UN726FTP
Max vacuum - 50 Torr/28 in. Hg
Max pressure - 20 PSIG
Free-Flow Cap - 17 liters/minute
KNF’s N726FTP series of contamination-free diaphragm pumps feature solid PTFE heads combined with our exclusive PTFE coated molded diaphragm. They are capable of pumping highly aggressive gases without attack to the pump or contamination of the gas stream.
Solid PTFE completely eliminates blistering or peeling of pump components, assuring the longest duty available for corrosive gas pumping applications. This pump is available in single-head and our unique twin-head designs fitted for either table-top use or for OEM applications mounted directly into your equipment.
(This one is the single head)
CONTAMINATION-FREE TRANSFER - The diaphragm design uses no coated-metal wetted parts. This insures a leak-tight seal and prevents contamination of the pumped medium while at the same time increasing system reliability.
PTFE heads and FFPM valves* are resistant to most corrosive gases & vapors, reducing periodic maintenance.

just spoke with their technicians, this pump suffers from the same problem that the gast pump has and that its not designed to have pressure on the inlet. and their technicians are calling me back tomorrow afternoon once theyve had time to mull over the idea i gave them.

Wow good work SS, very fast. I appreciate that.
Please post any follow up they provide you with.
I'm pretty sure I'm going to get the pump either way, I'm sure I will find a use for it. Any info you can share would be great.
Thanks again!

Just got emailed back for a Chinese refrigeration company for a anti explosion recovery machine with an oiless compressor, it's called the cmep-6000 , and they put that 6000 in there for a reason I was quoted 6600 per unit holy balls. Is this what safety is worth, I've also been looking into a pump from knf but the highest output they have is 100 psi is it possible to recover butane efficiently only using this type of pump ?
