The two stage pump has two impellers, one for suction and one for pressure. This is a good coice for an under ground tank or any application where the oil in the tank is below the level of the burner or a longer oil supply line. The extra suction impeller gives extra vacuum or lift to move the oil.
What are the two stages of a two stage oil pump?
How they work – Dual stage pumps have a low vacuum stage and a mated high vacuum stage in one assembly. The high vacuum stage takes in process gas and transfers it to a second, low vacuum stage that compresses the gas to atmospheric pressure, improving the vacuum performance of the pump.

The “oil pump”, properly called the fuel unit in most oil heating texts, draws heating oil from the oil storage tank, pressurizes the oil to high pressures of 100 to 125 psi (typically on modern retention head oil burners), and delivers oil to the oil burner nozzle where the combination of high oil pressure, combustion …
How much vacuum must a fuel oil pump produce to lift fuel oil up 6ft?
We need about . 75″ to 1″ Hg of vacuum for each foot we lift the oil, 1″ of vacuum for each 10 feet of horizontal run, and ½” for a clean oil filter.

What is the typical oil pressure for a gun type oil burner?
What factors should be considered when selecting an oil fired furnace?
Selection criteria is crucial and includes fuel, load, application (water or steam), efficiency, venting and system design.
Can a dual fuel heat pump be used with a natural gas furnace?
At that point, most heat pumps will turn on costly electric heat strips, but a dual fuel heating and cooling system utilizes an efficient natural gas furnace, saving you from high electrical bills in the winter.
How does a 2 line oil furnace work?
The two-line fuel system on an oil-fired furnace consists of a supply line and a return line. The supply line delivers fuel oil from the holding tank to the fuel pump. The return line sends excess oil not used by the furnace back to the oil tank.
