| I've been using this for a few munths to keep my WVO warm. It starts out as lard - so it's solid if I don't heat it. It's a Taco 007 pump, a 220 volt heating element running on 110 (forgot the wattage). The big pipe and tee are 1 1/4. Near the electrical box for the heater, you can see the trick adapter I had made for the heater. He faced the top surface of a 1 1/4 X 1 bushing, ran a pipe tap all teh way through to open up the threads, and cut a shallow groove around the element so that an O-ring seals radially between the bushing and the element. Inside the square box is a water heater element thermostat and hi-limit cut out. The box is welded to the 1 1/4 pipe for heat transfer. The grey bulbous thing is an expansion tank. Don't let it freeze. Several parts in the pump seem to not like it, but I took it apart and did some creative metal re-forming, and it doesn't leak - though it was pretty noisy for a while. |
