Waste Oil Heater Forum - Your definitive source for burning waste oil for heat.

Russ,

It's a Buderus and it's 6 to 7 years old. It was in storage about half of that time.

Looking forward to your boiler project. Is it going to be an indoor or a shed boiler set up?

russ,

 it's a shenandoah variable speed metering pump. i got off ebay. from a company called central ohio heaters. there is some good information at there web site.  http://www.centralohioheaters.com/Parts.html  they sell all kinds of waste oil burning equipment and customer satisfaction is very important to them. at the time i bought the metering pump it was cheaper to buy it thur ebay than thur thier web site .

russ, good eye on the pump it is a suntec a2ra-7710 pump. it has no internal relief valve.

the oil comes from the tank into a 140 micron filter, the pump is the mentioned above powered by a 90 volt variable motor and controller. there are two gauges on the assembly. the first is a vacuum gauge checking the draw into the pump. lets you know if the first filter is getting too dirty. the second gauge measures the pressure at the final filter and nozzle which normally shows 1-2lbs of pressure. this would let you know if the filter or nozzle is getting dirty. the last filter is a spin on automotive filter that is rated a 40 microns. it does have a pressure relief valve that opens at 11lbs. i have found a spin on filter that doesn't have a relief valve and when this one gets drirty i'll put that one on.
