What can I get that'll empty out a 55 gallon drum at a resturant fairly easily?

It needs to be able to pump thick oil in the winter without heating. (Can't wait all day for the oil to warm up.) as well as be able to handle whatever trash is in the oil.

The Fill-Rite fuel transfer pump is a bit expensive and doesn't deal with chunks too well...

My little oil pump with hose barb fittings doesn't look like it'll deal with chunks either... Plus it's rated for water. I don't think it'll handle thick grease well either.

I have available a 12 HP Honda Gasoline engine with a V-Belt pulley. I could hook it up to something.

What do you guys use?
