The numbers of pumping elements (two gears that pump oil), pressure and scavenge, depend largely on the type and model of the engine. Stabilize the gas from the contactor At oil burner school we learned to set the fuel unit pressure up to 110 or even 120, adjusting the nozzle size down to a smaller gph nozzle to keep the overall fuel delivery rate at the intended design point for the oil burner.
From a strainer, oil passes into the oil pump and then flows through the heat exchanger, where its cooled. belek saturday market; aboriginal clothing kamilaroi. Based off of what the engine demands, you design a rotor set or a vane that will meet those criteria. The valve is spring loaded because the pressure drop through the oil cooler could become too great due to denting or clogging of the cooler tubing. Below: Suntec Oil Burner Pump, 3450 rpm, 3gph, 100-150psi, model A2VA-7116 widely used on many oil burners. The gear-type oil pump has only two elements: one for pressure oil and one for scavenging.

An antidrain check valve is incorporated into the assembly to prevent the oil in the tank from draining down into the engine sumps when the engine is not operating. 
The direction of rotation of a fuel unit is marked on the fuel unit label (shows as our red arrow on this Beckett Clean cut oil burner fuel unit) or possibly on some older Sunstrand pumps as a casting into the fuel unit body. The filters generally discussed are used as main oil filters; that is, they strain the oil as it leaves the pump before being piped to the various points of lubrication. The scavenge elements have a greater pumping capacity than the pressure element to prevent oil from collecting in the bearing sumps of the engine. A shaft drives the first gear and the second gear is driven by the first gear. Most filters are located close to the pressure pump and consist of a filter body or housing, filter element, a bypass valve, and a check valve. The single-stage Sunstrand J-pump and the two-stage Sunstrand H-pump were among the most widely used fuel units we encountered when servicing heating equipment in the Northeastern U.S. Webster's M-series fuel units are also widely used as OEM equipment on a variety of oil burners found on residential heating boilers, furnaces, and water heaters.
