If its light enough oil, why not use more of a siphon type system like a spray mist set up. Operator could fill it any time without worry, and it would be super cheap to build.

Hey guys I am trying to find what I thought would be an easy find. I need a 1 gallon reservoir that is either clear or has a fill glass that has metal on top and bottom in order to screw NPT fittings into. But it also needs and removable cap and be able to be pressurized at low pressures.
This is almost perfect except I dont think it can be pressurized due to its design because it has a flip up fill cap.

Now this one is more of what I need but I shouldnt have to spend this much on one.

It is basically $377.00 for a tank and 2 regulators.
I can install the regulator and filter I need for $40.00.
Also I have had some issues I hope someone could have some input on. I am basically automating a tiny spray stream of light weight oil on a peice of automated equipment. It needs to be intellgent but I have most of the electronics figured out. My issue is with the fluid side of things. I first was going to put a valve on the air pressure going into the oil tank to make the nozzle spray that way. After a prototype I saw that even when I turn off air pressure the tank still holds pressure and the nozzle still sprays so I was going to go with a nozzle on the oil side.
Its better but still not as exact as I want,but I can deal with it. Some else asked why dont I go with a displacement pump on the oil side but thats more moving parts/noise and I dont know if the pump would have to be automated to spray the oil or if the pump would run continuous and a solenoid valve would control the spray. Also a consideration with a air pressurized oil tank is that an operator will have to refill it periodically. Even though it will only be 2-15psi I run the risk of operator error if they forget to turn the air of and use the relief valve to discharge pressure before taking the cap off.
I would like to take this out of the equation but i dont know which is the best route to take.
Any suggestions on any of these issues?

Post a link of something you have in mind,but maunly because they usually invlove mist or atomization.And with the nozzle being in open air near about 4 feet from an operator in is an OSHA no no.Has to stream or pee.Originally Posted by underthetire
Then i would just get a standard high pressure waylube pump/tank combo. They will push 200 PSI without a whole lot of volume.
SHOWA, BIJUR, LUBE, VOGEL, Devco Corporation
Even easier than air, just use a timer or smart relay/ whatever to energize the motor in whatever interval you want. ~600-1k bucks usually. They make less noise than air would.
Yeah its seems to be getting to complex to pressurize the oil supply tank because after testing even with 15PSI I would have to design an air cut off and pressure release from the tank for the operator to refill. Not only for saftey but even at 10PSI continuosly flowing into the tank makes it difficult to pur low viscosity oil without it being blown around. And I cant rely on operators turning the main air valve off for refilling.
Gravity fed lube is not an option either or syphon system due to the oil being mixed with air in these kind of systems. Is the only other option using a pump and what side pump would I need that can be small enough to produce 5-20 PSI?
And how would I control the pressure on it,a needle flow control valve?
What kind of pump is on that? How would you vary the PSI? It looks promising but my budget is $500.00 per machine being it is a small company.
By the way the heck does it mean under the reservoirs measurements when it says 83/4W?
Probably motor watts, but not sure.
You might want to check these out, since they have built in timers.

Since the volume is low on these type of pumps, pressure is adjustable either internally, or by nozzle size.
I found a easy solution for the tank pressure issue. A 3 way manual toggle switch. The operator will just have to switch it off before refilling and it will turn the air off and exhaust the tanks pressure.
Another thing I am concerned with is what will prevnt the oil(water like viscosity) from leaking out of the vertical mounted nozzle? I would assume the valve would be air tight and what if I include a check valve? I dont know much about fluid mechanics but it may be the ball valves I was using for thr prototype are not sealed nough but after I sprayed it still leaked after a little. I need this to be very controled so what the theory behind this?
I have a pesticide sprayer at my house which should be pretty darn close to the concept Im using. In fact it was my inspiration behind this project. But when I pull the trigger it spray and immediately stop and does not leak? This is what I need. So why is mine. Spraying,peeing then dripping. I know that doesnt sound right but it the best I can come up with.
Why you want a clear reservoir. You can simply use a metaltank with a hole on the top and bottom or on the side. In this you make a connection to a small clear hose and you can see how much liquid is in. These Solution is in the High-Temperature Large-Capacity Oil Reservoirs from your 3rd and 4th link.
