The search for a proper recovery pump..

[Chonkski]

had 2, broke 2. they run fast and lasted for a while. they also run quite hot, theres a video online of someone frying an egg on the pump. the appions use a radiator to cool the gas, where as the tr21's use the mt69. i do not recommend using the tr21's without a heat exchanger because the pump runs very warm and youll be warming up your nice chilled recovery tank.

How long was the average life between the 2?

I've found the solution guys.

The new pump! Made to work with r600, This will especially work large commercial purposes.............

lets rebrand them and sell um for huge mark up

 

[Chonkski]

Hehehe

All jokes aside....I'm almost considering trying one out. I'm sure it needs lube, so I don't know how clean it would be, or how airtight and safe it even is. But it would be like a cool mix between passive and active recovery. 'Manual active recovery'.. Lol

 

[hobb3s93]

'Manual active recovery'

guess u coined the term man haha. would be pretty cool if it works....

brings me back to the days of the desiccator and the mityvac hand pump

Haha! Sure have come along way.

Back when I tried the hand pump, my 'desicator' was a mason jar

Extracting cannabis sure has become a funny trial and error learning process for those who have been along for the ride the past decade. In fact, it was a little longer than a decade ago that I would blast through a 2liter bottle into a Pyrex and just let it sit out for a week until I would call it done! Lol

I know I know, that's pretty bad. But I was still a teenager. All those chemicals from the two liter probably made me a little loopy. Hehe

 

[SneakySneaky]

How long was the average life between the 2?

they lasted about 5 months of daily 12+ hours work. the mt69's will eat through some ice. the 2 together would go thorugh 100 lbs of ice without question. the old 5 gallon bucket solution was to put 10 lbs in, making the bottom flat and layered with dry ice, put a thin layer of regular ice on top of that, then put the mt69* in and bury it in ice. the only problem i ever had with this was when i hadnt cleared out the mt69 on initial use and some moisture got inside the coils and the dry ice froze the moisture in the coils of the mt69 and clogged it.

Starting with that creative gem and upgrading of course, to pump in both stroke directions and with two handles, like a hand powered rail car.

Recent human powered flight and land speed records suggest that a recombinant position and petals might afford the best long duration efforts.

Being lazy by nature , is the first requirement for being an engineer, cause work avoidance is how many of our creative juices first started whirring and so let me add one more level of evolution, to human effort assisted by wind, water, or solar electric?

All easy current technology, just requires bolting available parts together.

Brainstorming outside the box, what if instead of tolerating the Achilles Heel of oil less pumps, we found:

1.0 An suitable diaphragm pump rated for flammable vapors, that is priced low enough for ma and pa.

2.0 A suitable demand regulator to place in front of the diaphragm pump, so it sees zero inlet pressure, such as typically used on scuba gear and propane powered vehicles, and with components suitable for our pharma use.

3.0 A heat exchanger dropping the temperature of the diaphragm pump discharge to below n-butane's boiling point in a single pass, so no secondary refrigerant pump is required.

4.0 A more salubrious non petroleum pump oil, so conventional sealed oil bath pumps certified to R-600 can be used.

5.0 A highly effective oil separator, or cascade of separators, to insure that no significant amount was carried away by the gas stream.

6.0 A highly effective sub zero cold trap after the pump and before the storage tank, to remove pump oil and cool down the stream.

7.0 A means to subsequently scrub the gas stream through molecular sieve to PPB levels, to remove any trace amounts making it past 5.0 & 6.0?

Some of the directions we are looking at and an invitation for input from the rest of ya'll fertile minds!

I wholeheartedly agree with you! Which is why this would be a nice step up for those of us backing down to passive recovery, all because of these pump shinanigans that are blowing up the threads, no pun intended.

But I am with you when it comes to barreling onward unto the next stage wisdom and knowledge of this 'trait'.

Sounds like a wonderful solution, but how much extra cost does this involve? The diaphragm pump may be easily attainable.

Is it really an affordable option for Ma and I? Hehe

Or should I just keep long term planning on a haskel as soon as I can do that.

I'm very close to getting a tr-21 for the time being, because my second promax makes me feel more uneasy than the first...

I'm sure I speak for most of us when I say I can't wait for all the 'hazard' stress to be gone when it comes to equipment. I handle the normal workload stress much better.

whats wrong with your promaxes? the haskel is for serious work....the 10hp screw drive compressor is about 10k just to run the pump and requires 3 phase power...not a do at home option it would require no neighbors or a warehouse....but i also have haskel envy i think it might be cheaper to rent a warehouse and get one than keep burning through pumps at the rate ive been going.

 

[Chonkski]

I could not agree with you more brother. When it comes to serious work, this is the direction I'm going for. I hope to be in a warehouse by sometime next year

So far we are very very deep investment wise, so it's not worth it to compromise with these throw away pumps.

My first promax was with my first active system, which was the mkIII. Admittedly, I ruined the seals on that pump within the first two weeks due to a few 'beginner mistakes' like not throttling the valves etc.

Now that I have learned the ups and downs and built my own version of my ideal terpenator, the second pump is sketchy on holding a vac on the input side. Straight out of the box.

 

[Permacultuure]

I'm over the "search", if you, we or anyone looking at hydrocarbon extraction as anything more than a hobby should be serious about financially planning logistical upgrades, proper recovery being first on that list, assuming your operating the right machine.

I see these "main stream" extraction companies, who are not afraid to show how lucrative this industry can be, failing to make the proper upgrades until forced to by the state.

Reinvestment, progression and expansion is constant around here......

I'm stoked cause I've got three phase, on two different meters......but that damn screw....We hope to be running a 30hp screw before the end of November......with the assistance of the wonderful souls at Wolf Wurx....

Well put, brother.

Chonkski, can you comment more about properly throttling pumps? I'm only recovering to -15 or -20, but I'd like to know what more I can do to increase the lifespan of my pump.

I have seen the throttles for the inlet and outlet sides of the pump. Should I reduce it down so the pump works more slowly?

Don't turn your pump on until your gauge is above zero during flood....doing only one long single pass....... and I only recover to -15 to -20 with recovery pump. Then pull hard with vac pump , which should be done with something like a rocker.

I've managed to get away with using standard vac pump but do not recommend it.

I am more or less talking about precautionary techniques to avoid aspirating oil laden butane into the recovery port of the collection tank. But throttling the intake every time anything is entering the collection, whether it be from the vent or the dump.

Not only that but also the valves as well. Even the 'liquid line in' valve(s) when the psi rises to help cut down messy clean ups.

Hope I'm making sense!

Anyone looked at kimray electric glycol pumps?

http://kimray.com/Portals/0/Documents/G14067.pdf

These are diaphragm pumps, and they're available with SS and viton parts.

The spec sheet says nothing about vacuum, but im sure they'd likely pull a pretty decent amount without failure, sine they're rated to 2500psi.

We also use their suction controllers to regulate inlet pressure on nat gas compressors at my day job. They make them small enough, with SS and viton internals, and non vented for our application, BUT some of the packings are bathed in oil, and exposed to the gas stream through sensing lines. Also, the bodies are steel.
