The Clean Burn Pump
The oil pump is a key component in any used-oil furnace. As every mechanic knows, it is better to have a heavy duty component that doesn't have to work to the limit of its ability over time. That is why the Clean Burn Pump is made so "beefy," so heavy duty.

Compared with competitive units with plastic gears and overworked electric motors requiring fan cooling, the Clean Burn Pump features heavy duty steel gears encased in an oil bath, and precision assembly to help ensure a very long, very reliable service life. Oil flow is consistently held because precise gear ratios and pump speeds are set for each individual furnace. This maintains correct flow rates no matter what type of oil and viscosity is used and provides for optimum performance.

In short, if you were building your own used-oil furnace, you would choose a Clean Burn Pump, no question.
