The barrel is a "throw away" item from our local GM dealer in their service department.

The center PVC pipe houses a used hot water heater element.

The white PVC Pipe on the right is the suction line and the steel pipe in front is the discharge outlet.

The digital thermometer in the back monitors the oil temperature.

The center PVC pipe supports the hot water heating element. This unit creates the "hot stick" that is used to heat the oil. This is a 220 volt element running on 110 volts AC.

From left to right ... 1/2" pipe nipple to 1/2 x 3/4 bushing to PVC 3/4" adapter to 3/4" PVC pipe (not glued)

This is 1/2" pipe assembly. From the top down ... nipple connects to a pipe coupling (on top of the lid) with a nipple screwed in to the coupling from the bottom of the lid which connects to a bell reducer and finally a 3/8" nipple which completes the assembly.

The object of reducing from 1/2" to 3/8" ... increase velocity of the hot oil which helps agitate the oil / methox mixture.

The vinyl hose heading up leads to the PVC suction line.

The vinyl hose on the right is the discharge side of the pump and leads to the discharge fitting above.

When the methox carboy is empty the red valve is shut.

The input and discharge are both 1/2" pipe thread.

I would estimate the pump produces around 10 GPM

I simply lower the probe into the hot oil and read the temperature.

Time will tell if the methox will destroy the probe but so far so good. 

The hot stick has a wire running through to keep the heating element off the bottom of the barrel.

The thermometer probe is lowered into a small hole drilled in the lid.

I have been making 38 liter (10 gallon) batches with used french fry oil from a local restaurant.

Using KOH base of 7 grams and a titration of 1.6 grams per liter mixed with 8.7 liters of menthol alcohol.

After a settling period the glycerin is pumped out using the suction line and discharging into an empty carboy.

By raising the suction line off the bottom by an inch or so the new biodiesel is pumped through a "Golden Rod" filter (which is threaded directly to the discharge line) into a storage tank or without the filter to a wash barrel.

• The pump is self priming
• The pump is portable and can easily be
  used with my Appleseed proccessor
• One pump can do all the pumping
  operations
• To make another batch simply get
  another barrel and start over
• 30 or 55 gallon barrels could also be used
• With the exception of the pump ... the
  parts are very inexpensive
• Suction and discharge hose is 3/4" ID
  vinyl tubing which slips over standard 1/2"
  pipe nipples
