Waste Motor Oil / A partial abortion
« on: January 18, 2016, 02:50:21 pm »
That's the mess I walked myself into..
Got a friend, a mutual friend of ours used to install waste oil burners, set this "Blackgold" brand heater up for him in his garage.. Well my buddy moved to bigger shop, and I helped him move heater to new shop.. Now it wont pump oil uphill 6ft..  A couple of the copper lines had terrible flare jobs done originally, so I replaced them with good tight fittings.. I took the pump out of line, stuck it in a bucket and ran the shaft with a drill.. I figured even the lower RPM of a drill would produce some dribble or something out of the pump... Nothing
The original "DELTA" brand pump model # CV2RR is next to impossible to find, I managed to cross it over to a "Webster", but that model seems to be only available from factory, special order...
It has check valve on bottom of suction line inside tank, seemed to move freely... It has another check valve AFTER the pump, which I don't think is really necessary, (Once the oil goes up, the check valve in the tank should keep it there right ?)
I am at a loss,,
I even went so far as to blow compressed air into the tank, pressurizing the backside of the suction tube, and then took the line off at the burner, and wrapped my hand around it so that I could use a shop-vac to create suction,, all while the pump was running.. Not even a drop...
Help !!
