Anybody here know anything about hydraulic systems?

[Begle1]

How do I get this to work as a water injection pump?



Thanks.

ditch it and bust out the $75 for an actual pump?

I already got one of those little Shurflos, but this one does 3000 PSI!

Would this work?



Would the reservoir have to be pressurized? Do relief valves work like pressure regulators? Anybody know if there's such a thing as a 1000 PSI relief valve? Nitrous solenoids would work with water, right? Are they big enough?

[Begle1]

Here's a hydraulic regulator, $90, 3550 PSI max rating, adjustable output from 100-1000 PSI. 3/4" input and output, 50 GPM flow...

I really need to get my pump so that I know what the line sizes, pressure and flow ratings are.

I'm probably going to need to find a pulley so that it doesn't over-rev itself to death.

Hydraulic pumps make more PSI if you use oilas it is thicker. I would bet that thing push MAYBE 600 PSI on water. The drive mechanism probaly NOT set up for water so things inside might not have as close of a tolerance as a water pump.

Looks like a power steering pump to me. It probably has an internal pressure relief already.

also the durability of water going througha hydrolic pump is questionable

#1, That's a Fisher snowplow pump.
#2, It's a gear type pump, no pressure relief in it. Relief valve is in the control valve on this system.
#3, Water will rust the inside of this so fast you wouldn't believe it. If you let it sit for a couple of days, the bearings and gears will start to rust, and then you'll be pumping that into your engine.
#4, On a gasser that runs 1-1. I have gone 1 and 2 inches smaller and didn't hurt them any. I was using it on a plow though.

Hope this helps ya!

Oooh, the difference in viscosity resulting in a drop in pressure... That's a formula that I could calculate actual numbers off of, isn't it?

The preliminary idea was to cut the fumigated water with this stuff. I'm not a machinist, but it talks about being a lubricity increaser and corrosion inhibiter. Would that solve any problems?

Pete knows his pumps!

If the water injection idea doesn't pan out, could I use it as a lift pump?

[PToombs]

It's non-flammable! What good is that?

Hey, you know me, always trying to pump something!

If you wanna use it as a lift pump, make sure you get the regulator!

[Begle1]

Alright, I got the pump in the mail.

5-inch pulley (outside diameter), 1/2 inch shaft, 1/2 inch inlet and outlet.

Now, I looked all over this thing for some kind of identifying mark, and there isn't a one.

Any ideas on how to find the specs for this thing? I looked through Fisher Plow's website, and they don't mention pumps anywhere...

Any experienced guesstimates on what it's going to flow and what RPM it's going to destruct at? Those two things are all I really care about...

1:1 ratio on gassers, that means that pump RPM equals engine RPM? For a 1:1 ratio the pulley on the pump would be the same size as the pulley on the engine, right? A smaller pulley on the pump would make the pump spin faster, bigger pulley would make it spin slower?


I took some pictures for the sake of documentation.

I don't know where to find specs either. It looks like a 70's vintage pump.
Yes, that's exactly what 1:1 means, and you have the pulley size thing figured out. We used a 3 inch on them with no problems. If we went smaller, the belt would slip when we raised the plow. A combination of not enough belt contact on the pulley and the pressure needed to raise the plow.

[Begle1]

So how fast were you spinning the engine when you were running them with the 1:1 ratio? Was this on a 2000 RPM skidsteer or a 5000 RPM Datsun?

I would think that a junkyard AC clutch should work fine?

Know if gasser first gens or anything else has the same serpentine belt as a first gen Cummins?

[flashgordon]

correct me if I'm Wrong but, that is an A/C compressor....the one on the right in the last pic....................

And if it is a A/C compressor...................does the compressor not compress gas (Vapor freon) not liquid????? or do i have this backward?????

Flash.

[Begle1]

The one on the right is the stock air compressor that I took off my truck so that it would go faster.

The one on the left is the hydraulic pump that I'm going to put on my truck so that it will go faster.

They got the same size shaft, seems to me like I gotta find a new A/C clutch to mount on the hydraulic pump.

Need to find a way to mount the pump itself too.
