Fuel transfer pump is a very general term, and essentially covers any application where fuels, oils and diesel are handled. A typical use of a fuel oil pump includes the bulk transfer of a fuel from one receptacle to another, whether this is a drum, IBC or storage tank. They can also be used to directly fuel a vehicle, machine or generator and may in this case be part of a larger fuel oil transfer pump system or skid, complete with hose reel, valves and meters. 


Other example applications include fuel oil circulating, fuel boosting and fuel injection. Screw pumps or gear pumps are usually the pump types specified for fuel oil transfer applications, but performance requirement will differ depending upon the application at hand. However, centrifugal pumps can be selected for diesel transfer as the viscosity is closer to water, and they are able to achieve high flow rates at low discharge pressures.
