Buse Monarch 7.50GPH, 45PLP

This oil nozzle is a Monarch 7.50GPH, 45PLP. It belongs to the category of precision consumable parts that atomise fuel into a fine spray for complete combustion. The nozzle is identified by manufacturer codes 0984230 and 732.892.042, and its catalogue article is 732.892.042. The designation indicates a flow rate of 7.50 GPH and a spray angle of 45 degrees; the pattern is given by the code PLP, which stands for a specific spray geometry. No further details on thread or pattern interpretation are available from the data. Parts of this type are selected by matching three parameters on the burner data plate: flow rate at reference pressure, spray angle, and spray pattern. Using a nozzle with the correct rating but the wrong pattern can cause sooting, pulsation, or unstable ignition. All three must match for reliable operation. When replacing a nozzle, always verify these parameters against the burner specification, and note that the pattern code (hollow, solid, semi-solid) is as critical as the flow and angle. This nozzle is a direct replacement part for burners that specify a 7.50 GPH, 45-degree nozzle with the PLP pattern. It sits at the end of the oil supply line, after the pump and solenoid valve, and sprays into the combustion head. Ensure the thread type is compatible with the burner’s nozzle holder – if in doubt, compare the thread on the existing nozzle. No additional compatibility, materials, or approvals are provided in the source data.
