So i'm going to start to building my meth injection system fairly soon and I'm wondering what the best pump would be to run straight meth. From what i've read, meth can't be run through many pumps because it tends to eat away at many materials. I'm not sure of all then numbers yet, but i want a pump that will be able to make 22-25 psi on pump gas safe with a GReddy T88

I'm not seeing any info on pumps on that site. I see two kits, but they don't say anything about the pumps.

 

I think most everyone is using the surflo pumps:

What the difference between a switched and bypass pump?

 

Most of the larger alky companys use custom pumps. 150 psi pressure switches and seals that are meth compatable. Some of the smaller ones still buy standard pumps and mod them to be meth compatable. The seals on the pumps from systemacc or northern will need to be switched out if your plan on running straight meth. You will be hard pressed to buy the pump, seals,and pressure switch cheaper than most alky vendors sell them for.

 

I have two pumps on the bench, one is a Alkycontol, the other is a Snows boostcooler, side by side they look the same, anybody know if there is a difference?? and whats with the Snows double chamber nozzle, says it improves atomization? anybody? Ron

 

Depending on the age of snows pump its liable to have viton valves. Vs having mtbe in the alkycontrol pump. If your going to run the straight 100% meth i would use alkycontrols pump. I am not 100% sure when they started getting custom pump 3-4 months ago that they switched over to mtbe or buna.

I know we did switch when could buy a custom pump straight thur shuflo, and this kept us from having to do it manually like alky controll still does.

I have not heard anything about snow having a new nozzle. Do you have a pic?

 

you have any meth kits devil? i saw your site but only saw the alchy/water kits.

 

Any pump that has either Buna or EPDM seals will be 100% methanol compatible. Viton has a good heat tolerance but can not run more than 50/50 mix. Buna handles 100% well, but cant handle very high heat (180-200F). EPDM can handle high heat and Meth. We use EPDM in our pumps.

 

On your site I only see one pumps and it says a max of 50/50 mix of meth/water. Where are these 100% pumps that you speak of?

 

The pumps on our site sold as of today are capable of 100% methanol and EPDM seals. The "50/50" warning is simply a disclaimer from Shurflo the manufacturer and us for flamability. They required us to put that waiver on our site.

Thanks.

 

Ahh, i see, Makes sense. What is the GPM rating on that pump?

 

The standard rating is 1.0 GPM, but that is with the old viton seals. The EPDM seals are more flexible so the max flow would be a little more, but not significant.

Also, the flow rate is highly dependent on the pressure in the line. The more pressure, the lower the flow rate. So its a bit deceptive to just assume 1 GPH because the pump says it.

 

Karack Methanol is a type of alcohol. So this is what the kit is designed for.

You nozzle size is what will ultimately determen your actual gph. Smaller the nozzle the higher the pressure. The largest nozzle we sell is 14gp Hour While the pump is capable of 1 gp Minute So the pumps are plenty big.

 

i know but i keep hearing that certain pump seals can handle alcohol but some aren't tolerant of methanol. i guess i was just reading into it too much, so ethanol and methanol both require the same pump seals?

 

I've been running straight meth on my surflo pump with viton seals for about 2 years and it is still going strong.
