Finally got my WMO pump assembled

After much procrastination, I got the pump built and dry tested. Havent got to move oil with it yet, that happens in a few hours when I get off work.

Basicly I follwed the instructions on how to convert a chevy small block oil pump into a transfer pump, and coupled it to a 1hp washer motor. Ill report back on how well it works.


Here is a few pictures.

Looks just like my setup. I haven't gotten a coupling yet, what did you use?

I use the gear off the end of a junk chevy disributer. I punched out the pin, removed the gear, took a 1/2 bit to make the large enough to fit over the motor shaft. Put the pin back in, and pounded the gear onto the end of the shaft, untill the pin stoped it, then the slot on the pump fits in perfectly.

I have a similar setup & it works great. I sometimes use it with a 1/2hp motor, but usually just w/ the 1/2" drill.

perfect for use with a centrifuge.

that would work just for transfering oil into my main storage tank right?

Yes it will work. I built one and it pumps about 7 gal per minute just using by 18v drill. I have never timed it hooked up to the 120v motor.

Nice

Looks good! I think I may need one of those, would this work as a recovery pump? Would it pump oil out of a container on the ground and pump it up into a drum in the back of a deuce at a reasonable rate?

Have the same set up. My prob is that I'm not sure what pick-up hose to use that can handle the type of fuels and not collapse under suction. Would like to be able to run a long pick-up hose. Have tried a few things and I keep getting sections sucked flat. Would also like to NOT spend HUGE amounts on the hose.

That is what I'm doing w/ it, only into the 105's tanks.

Looks like a good idea.

sounds good! About how long does it take to fill a 55gal drum?

that looks like it will work well,ANOTHER reason never to throw anything out.

be good to hear how well it works.

suitable pump

Now THAT looks a great candidate for a nice Pre-prime oil pressure pump for a deuce or 5 ton. (as) It seems it can be driven? by a moderately powered 12/24volt motor?...... (now, for to me to find n' old chevy engine or similar..somewhere ) but that IS going to be my very next project..and I will keep that progress posted...

At this point not really sure. I've just added that on to the trailer and used some cheap garden hose to test it . . . the hose collapses when I'm sucking up thick oil.
Today we dropped about $100 on some hose that will stand up to fuel and (hopefully) will not collapse.
Won't be drawing any more fuel for a few days while we travel. Will be having to get more in a couple/few days.

It can be driven w/ a 24v electric scooter motor. Right now I've got it hooked to a 1/3 horse motor from a swap cooler and that works, but . . . I need to have it powered from the 24v so that I can draw from anywhere.
The main prob that I have w/ the pump is that it's meant to be submersed and so it doesn't run gaskets between the pieces, therefor it weeps. I've talked w/ the "Hot Rod" guys here that all run chevys and they say you can put gaskets in between because you will lose the pumping.

I've also heard that you can mod a power steering pump to work. That might be better being that it shouldn't weep.

What did you get for hose lowtech? I would think old hydraulic hose would work well. It is designed for extreme pressure with steel braiding but I cant imagine it getting sucked shut by a sbc oil pump sucking wmo.

Try some Permatex #2 on the pump cover.

ok, seeing this thread prompted me to build one. i threaded the barbs in and can use the pressure relife feature on the pump and use a supply handle if needed or in case a filter gets cloged. with the 600 rpm drill i get about 4.5 gpm,not enough for recovery transfer. im looking into a 1040rpm 1/3 hp motor, it should deliver about 8 gpm then, i am also going to try a 12v genny starter motor and see what happens. next one i build i think i'll use a bbc pump.
