pumping wmo

does anyone think large diameter PVC pipe with end caps on it (sealed) could handle the 20 in of vaccum and then 40-50 lbs of pressure on it regularly? I got to thinking a 36" diameter PVC pipe about 4' long would hold alot of oil and be WAY less heavy than a similar size metal tank. Sure would make life easier unloading it out of the back of the truck when empty

Schedule 40 PVC should handle it. Many city water pressures are over 60 psi. Should be able to find schedule 40 rating limits with an online search.

If it don't work,,, and cracks under pressure... it's little oil mess.. right? Ugggggh.

got the washing machine motor, got pullies, just need to find out which wires need power to make this dude spin, put the pullies on, and mount it all up, I have tried every possible combination to make it spin and I just get a hummin noise, no spin.

You most likely need a starter capacitor. What wires do you have and what do you have hooked up?

G MAN, Can you use the Vac pump on the 7.3 to create a vaccum? Right now mine is not even hooked up to anything.

I dont know about vacuum but I have heard NEVER used PVC/ABS/CPVC for compressed air. It can fail and send plastic shrapnel everywhere. Thats why for shop air you only use copper or black iron/ galvanized pipe.

oil pump

What I have found handiest is to buy a remanf small block chevy oil pump from a guy on Ebay. It costs about $50 bucks plus shipping. I then use a 3/8s drill to power the pump. With my setup it takes about 8 min to empty a drum of motor oil.

Take a look at the guy on Ebay's listing and decide if you want to make or buy the pump.

I can use my regular 120 volt drill or my battery drill. The battery is only good for about 40 gal.

+1 for SBC oil pumps

I use a carbonator gear pump meant for pumping hot fryer oil off of ebay for moving oil from drum to drum not the fastest but does the job every time.

well the set up got held back a bit because i need a capacitor to make this motor work and someone came into my brothers yard and stole the remains of the washer that had the capacitor on it. In short if you try to use the method of the pump and motor try to make sure your motor is a simple two wire type. I have been told to look on old dryers and big shop fans for one of these.

You ask a question I don't have an answer to since I've never tried to use the stock vacuum pump straight off the 7.3/6.9 to pump down a vacuum on the collection tank.

Best I can suggest is to hook up a vacuum line and a gage to the pump and time how long it takes to pull 10 to 20 inches of vacuum on your collection tank.

Please let me know how it comes out.

I know this thread is pretty old, so I'm not sure if you ever got your motor/pump working. I am in the process of setting up a WMO centrifuge using the modified SBC pump and a washing machine motor, 115v 6A 1750RPM.

My motor, like yours would only hum when wired up POS, NEU, GND. I had an electrical engineer I know look at the wiring diagram, he discovered that the motor had a built in start capacitor. In my case, all I had to do was connect the red(start cap) wire to the black (pos) wire and the brown(who knows) wire to the white(neutral)wire. Now it fires right up, no humming or needing to start the motor by hand.

Just a word for the wise, I blew a GFCI outlet trying to figure out which wire was the start wire

I still need to modify my sbc pump and figure out how to attach the two.

Will an old how water tank work under vacuume?
