Haskel pneumatic refrigerant pumps

[gholladay]

Does anyone know have or know of someone who has either the 59025-3 or the EXT-420's on hand and willing to sell?

I contacted Haskel and the lead time of either of those units is currently 56 days. 70 days for the EXT-420-2. My team is looking to make a purchase soon and I was hoping someone around here might have scooped an extra.

Thanks,

GH

Wow, looks like i should place my order now if i want it in 2 months lol

 

[gholladay]

Thats awesome! I would love to do that! Bet you were all fuzzy feeling all day lol. Peacocking around and shit. Look! Look at this! j/k

Im really leaning towards the haskel here next month, but the space and noise are the only down side. Im in a warehouse strip so i dont know how the neighbors would like 2 compressors running 10 hours a day lol. But i could and just say deal with it lol. Also the fact i run multiple machines at the same time which brings me to my question.

Is there anyway to get the haskel to rum multiple machines? I know it would be impossible to run differnt sized machines as they would just recover at the same speed and the small one would take just as long as the big one, but could i at least run 2 big same size MKV's?? Only way i could think of would be having 1 large 200# or more tank feeding a 1" cooling coil then multiple machines and an intake manifold on the haskel for machine recovery selection correct? Would it even be capable of that? You say its meant for more then what we use it more. I want to take it to its max potential lol.

A6,

Are you talking about having the haskel switch between which basin it's recovering from? ie doing them one at a time, separately. Or saying it would be pulling from both pots at the same time?

I think I remember this topic being discussed somewhere else and I believe you don't want to try to recovery from two different collection basins at the same time with the same pump. I think the inevitable differences in pressure between the two pots would cause the pump to not pull on them evenly.

I know one guy that is running two subzeros off one Haskel. He has to time the runs and recovery perfect. I'll ask more details when I see him again. These pumps are quite versatile and can take a beating which tends to happen during r&d

On a side note I was able to get the Haskel to recover below 0 in single stage mode. We determined it was because the after chiller was reducing the back pressure low enough to allow a vaccum.

You can recover any number of pots with one pump, but they won't recover evenly, so finishing becomes an issue.

You could use one Haskel to rough everything out and then switch to individual pots to finish, or use a secondary pump for finishing.

Perma and GW,

Thank you!

So yesterday I had the pleasure of hosting Dave from Haskel and Joe from HIS Innovations Group. First off these two gentleman are a pleasure to talk with and work with. I got to show them the pump in action and we discussed the benefits of the multi stage operation of this pump.

This pump is amazing, it's pretty much bullet proof and a very simple design. It's built for a much heavier work load than we require, as opposed to hvac pumps that aren't designed to be worked so hard.
We had the single stage mode pulling into the negative bc our after chiller was working so efficiently!

NO YOU DONT NEED 3 PHASE!

I highly encourage calling Joe at HIS if your in any way serious about your craft. He has the knowledge, pumps and connections to get you running, and for about the same price as two cmep ol pumps, if you don't have three phase. Not to mention he's a solid guy embracing our industry and much more to offer than pumps...

Having someone like Dave on our side and helping advance the pump design is an invaluable asset. There is no pump that compares to this, and no matter what china does I doubt it will ever compare to this work horse.

Thanks for everything Dave! Your a huge help!

Permacultuure, thanks for the kind words! It was great to see you and see your operation.

I had the opportunity last week to meet with several readers of this board, it's always great to put a face to the screen name.

Thanks for the warm welcome everyone!

I see some discussion about your one pump on two different pots. I would agree with what has been said, it is possible to hook each pot to a different side of the pump, but if the pressures vary between the pots, it could be tricky keeping the pump running evenly.

Thanks,

Dave

Dave,

What is your recommendation for the set pressure of the pressure relief valve after the haskel? I'm planning to install a gauge and a swagelok pressure relief valve after the haskel pump and before my chiller coil. I spoke with a rep in Denver that recommended 175 PSI. He picked this value by estimating a max inlet pressure from the system of 50 psi and a max outlet pressure from the haskel of 150 psi and then making the set point 15% higher, ei 175 psi.

My tank has a pressure relief set to 400 psi that is included. I believe 175 psi is well under the burst pressure of any of my components past the pump, so it seems like it should work.

GW, what do you set yours to on your turn key models?

Thanks,

GH

We put pressure reliefs on the pot and columns, but not the tank, which is rated at 400 psi, meaning the burst is around 1200 psi.

If we control the air pressure on a 4X pump, we control the output pressure, and have no reason to expect excursions above 400 psi. If you feel the need for one, I would set it below the rupture disc or pressure relief valve on the tank by 100 psi, or so.

GW, that makes good sense. I will have a pressure relief on my tank and column, so maybe I just don't need one there. I thought it might be a good idea to have a pressure relief before my chiller coil after the pump, in case of a blockage, but I suppose I could just install the pressure gauge and not the relief and inspect that part visually.

I think the main reason I was planning to install a relief there is because it was recommended in the Haskel literature to have a relief installed after the pump. I guess the relief on the tank would qualify for this?

Thanks for all the input!

Dave can speak as to Haskel's thoughts, so don't take mine as gospel.

The joker in the deck is the inlet pressure, because a Haskel can tolerate up to 1200 psi outlet pressure.

In our case, inlet shouldn't be over about 50 psi using butane or even propane mixes at lower temperatures and we have a 4:1 mechanical advantage with the different sized pistons.

If inlet pressure doubled to 100 psi, we would have reason to be concerned, and intervene, but not in imminent danger of a ruptured tank.

Seems pretty straight forward to me. If I get the go ahead from Dave I'll probably set it up like that.

Gentlemen:

As Gray Wolf said, the EXT420/59025 is rated up to 1,250 psi structurally (but you can't get to that pressure with this application). Where you set the Relief Valve is going to depend on the maximum pressures that other equipment/plumbing in the circuit is rated to. We normally set Relief Valves at about 10% above the normal operating pressures of a system (as long as that wasn't above the maximum rating for the system), however that might be a little tight in these applications because of the relatively low operating pressures.

Remember, I'm a pump guy, not an extraction expert, if you tell me what you need, I can help, but the process is yours and you know far more about what the limitations are than I do (especially when it comes to the chemistry).
