What Is a Fuel Transfer Pump?
In order for fuel to be transferred from a fuel tank to a vehicle or other location, an apparatus known as a fuel transfer pump is commonly used. Fuel transfer pumps are relied on for a grand number of vehicles and operations, ranging from the fueling of a forklift truck to the operations of utility vehicles found within quarries and construction sites. Depending on the type of liquid or fuel that is being handled, as well as other various factors, there are a number of common fuel transfer pump types that one may take advantage of. In order to find the correct fit for a given application, it can be useful to have an understanding of the various differences between types.
When choosing a fuel transfer pump, one consideration that should be made before a purchase is what flow rate is needed for a given application. Generally, the flow rate will be dependent upon the size of the fuel tank that is to be filled, and speed should be manageable. If fuel is transferred between the tank and vehicle at a pace that is too quick, the fuel has a chance of spilling or frothing. These issues can result in the premature shut-off of the automatic nozzle, preventing fueling from being carried out properly. In general, there are a few types of speed ratings that may be chosen from, each of which caters to varying types of vehicles and vehicle sizes.
Low speed rates for fuel transfer pumps often sit around 50 liters per minute, and such speeds can be useful for smaller vehicles such as a car, forklift, or van. For larger vans, trucks, and various public service vehicles, a medium speed of 70 liters per minute may be fitting. Large capacity tanks utilize a high pumping speed which is around 90 liters per minute, and such rates are commonly used for buses, quarry vehicles, mining vehicles, coaches, and more.
Beyond the speed of a particular pump, one may also determine the type of assembly that they need and the protective features required. Pumps are often either bare or cased, the bare type being an assembly that enhances airflow for increased cooling. Despite this, their resistance tends to be lower than the cased type. With a cased fuel transfer pump, such apparatuses may be well protected from dirt or moisture that may be present within the surrounding environment. Generally, the cased version is best when operating in a work site, on a farm, or within another environment where moisture and dirt is present.
One last consideration that may be made is the type of operation that a pump provides. Hand pump variations are more simplistic, requiring the user to rely on their own force for the means of transferring fluids between the tank and vehicle. These can come in many forms, common examples being rotary hand pumps, suction pumps, and lift pumps. Battery powered pumps, meanwhile, may operate on various voltage levels for the means of transferring fuel. Ranging from 12V to 230V systems, such pumps may be useful for excavator equipment, plant equipment, diesel pumping equipment, and much more.
