Hot cold anytime of the year what pump will pump used veggie oil from waste dumpsters year round? I have bought the little $150.00 pump from Northerntool.com with the gas filler hose that hooks up to a battery. I got roughly 4-5 uses before I burned it up. I sent it back to northern (exchanged for new one) and burned that one up in less than a month. Outside temps were 50* so the oil was slow going.
So I thought I was buying the mack daddy pump I went to northerntool.com and bought a 5hp honda engine powered trash pump. Spend over $150.00 on those braided hoses with quick dissconnect for both ends. Never could get the thing to prime. Tried for 2 months every weekend to get the sucker to suck oil it wouldn't ! Had even 2 mechanics look at it and they took the pump apart and the seals were in brand new condition. The only way it would pump water or anything is if it was fed into the pump (like flowing creek) but nothing stationary would flow.
Is there a better settup? I don't want to be behind a building for an hour trying to pump out 100 gallons of grease. I would like to find a pump to transfer this grease from tank to tank at a rate of lets say 15+ GPM
I use a 5.5hp gas powered trash pump on the bus, and it works great. It has the power to pull from a dumpster quite a ways away, and can still push it through our filters. I used to use the transfer pump from Northerntool, but that was too slow (we've pumped up to 200 gallons at a time with the bus), so now I just use that between tanks.
This past summer, we did have some trouble getting the gas pump to prime itself if we drained the hoses, but most of the time all we had to do was open the plug on top of the impeller housing, fill it up, and away it would go.

Research super sucker on this forum. You can make a sucker tank that will do about a gallon a second for pretty cheap. Myself, I built one with a 55 gallon propane tank and now i can get back behind the place, suck 55 gallons of oil, and leave within 4 minutes.
I use a 2 inch trash pump with great results, less than two minutes for a full 55 gallon drum. I do know that the first use takes a while to prime. Maybe two to three minutes if I have not used it in a while. I do have a couple stops that I have to add additional hose on the suction end. That really slows down the prime, so I always get them last. If the pump has a priming port, I would definitely use it, carry a gallon jug with WVO in it and give it a pint or so and then start the pump until it starts to suck thru the hose.
The other alternative is to build a super sucker.

so do you throw your sucker end into the drum them take the cap off and prime it with WVO then start? Or do you prime it start it then throw the hose into the drum of used oil?
I put the wand in the oil, open the in line valve, and then start the pump. If it doesn't want to suck within a couple minutes I shut down the pump, prime the pump and then start it back up. You will only try to prime it with the pump running one time. I know, it was not pretty.

A few months ago my 12V transfer pump crapped out on me, and I was needing to empty my source's grease tank. Instead of going out and dropping $350+ for a new pump, I took an old tractor PTO roller pump (the kind used for ag sprayers) that I had laying around, made a crude little stand for it and hooked it up to a 1/3 HP electric motor. I have it spinning at about 1000 rpm's, even though it is supposed to be for 540 rpm, and it works better than any pump I've ever used. It'll prime itself up to about 10' of lift, and it will pump about 20 gpm. I've only pumped oil down to about 60 degrees with it, so I'm curious to see how it will work this winter. My supplier has a receptacle on their back dock, so I don't have to take a generator, and I don't have to worry about making lots of noise with a gas engine.
