What is the typical pressure of a residential oil-burner pump?

The typical pressure of a residential oil-burner pump is around 80 psi. This pressure is sufficient to ensure that the oil is effectively delivered from the storage tank to the burner, allowing for proper combustion and efficient operation of the heating system. Oil-burner pumps need to maintain this pressure to overcome the resistance in the lines and ensure that the oil is atomized effectively for burning.

At 80 psi, the oil is delivered at a pressure that allows for efficient spray patterns, which is crucial for maximizing the heating efficiency and ensuring a clean burn with minimal emissions. This level of pressure helps to prevent issues such as incomplete combustion or the formation of soot, which can result from inadequate fuel delivery.

Other pressures listed, such as 10 psi, 2 psi, or 200 psi, are either too low for effective operation in residential heating systems or too high, potentially leading to equipment damage or safety concerns.
