Default alternate high pressure water injection pump

check it out:

http://www.northerntool.com/webapp/w...=53251&R=53251

not cheap @ $200, but 220psi w/built in regulator, stainless/teflon/viton construction.

talk about atomization...

Wow.. I dunno.. I haven't had a problem at 100PSI, but I can only imagine 200 PSI. Nice find!

Many types of nylon tubing are beyond their max pressure rating at 220psi if the tubing gets to above 68F. For people who use rubber tubing, the pressure rating could be even lower. I've also seen solenoids and fittings that aren't ment to hold that kinda pressure. At least that's what I've heard. Also, why use a heavier/bigger pump which eats up more electricity then the already heavy/bulky surflow pump when the surflow pump works fine?

peace

edit-I was wrong....

I have tried that pump many years ago, very powerful. It is not easy to use conventional inline valve to control of that kind of pressure. The pressure regulator is a very nice touch indeed.

100 psi works fine for me. I can't imagine a situation where I would need that kind of pressure. Probably end up with lines exploding all the time.

richard,

will your hsv handle 13-14 bars of pressure?

IMHO, there is absolutely no benefit to running 220psi for water injection. If you need anything near this for decent atomization, then your nozzle is junk. Unless of course you want to run ~100psi of boost, then you need something in this range to give you a good pressure differential across the nozzle opening.

I assume you just posted this because we're all mechanical geeks and like high pressure etc

No, the HSV can handle up to 10.5 bar and that is all.

I do have a customer that runs 4.5 bar of boost (gauge) pressure

Ahh the wonderous world of twin-stage turbo diesels. 67 psi is nothing to them. There are some over 200 psi of manifold pressure!!

On a turbo-diesel engine, it'd be kinda neat to integrate the fuel pump with a water pump running off the same drive but with different lines (obviously). Then you could have your ridiculously high water pressure without a seperate drive or electric motor. It'd just be like a second fuel pump and could be electronically controlled just the same. Talk about swish!

Wouldn't be much help for us gasoline folk though ...

for those folks running 200psi manifold pressure as SaabTuner described, 220psi is not enough

It is a good idea to post new and useful discoveries to the board. I used that pump for those two-stage turbo tractor pulling applications. Even with those high pressures, that pump has eventually given way to a mechanical pump driven by the engine. The water injection used on those application was not just for cooling but power production due to the additional cylinder pressure from steam. You should see the steam coming out of the exhaust pipe, it is very similar to a sauna room.
