For pumping gasoline fuel and diesel, as well as other types of viscous liquids, for example fuel oil and oil, a special pump is used to pump fuel. This equipment on the market is presented in a very wide range. So how do you choose the pump you need?
When buying any pumping equipment, it is worth paying more attention to two fundamental factors: economy and speed ratio. But first of all, decide on what task the pump for fuel transfer, purchased by you, will have to cope with. So, for example, if you need to provide a certain level of pressure, then it is worth choosing a device in which a multi-stage system of impellers operates. To implement a large head, a centrifugal pump is purchased to pump diesel fuel. Propeller or axial devices are used by those consumers who need a large volume of liquid supplied. Their downside is lower pressure. The most commonly used steel jet pumps for the transfer of diesel fuel, all petroleum products and gasoline. The fundamental advantage of these models is the absence of moving parts in the structure.
But the low efficiency is a significant disadvantage of such equipment. If your plans do not cost you to buy the device with the highest economy of operation, you can buy a whirlpool pump for fuel transfer. This is one of the cheapest equipment. In addition to low cost, vortex pumps for fuel transfer have the following advantages: small weight, small size, ease of operation.
Do not forget that the internal design of various devices is also different. And the factor influencing it is the goal set for the operation of the equipment. Only in this one segment of pumps there are many classifications and modifications. Therefore, in order not to get confused in all this abundance, we will study one, the most common. According to one of the classifications, all pumps are divided into dynamic or volumetric ones. They are distinguished not by the type of liquid pumped by them. The main indicator is its purity.
If it is necessary to pump viscous clean liquids, that is, without impurities, then it is worthwhile to use volumetric pumps. These models convert the energy of the engine into liquid energy. And this feature is a big advantage. With this work, not only the energy losses, but also the operating time, are greatly reduced. Another big plus of such pumping systems is the possibility of self-absorption. But there are also disadvantages: during their work there are strong vibrations, which requires the construction of a very strong foundation.
If you need to pump oil and fuel containing impurities, in a word, of lower quality, then use diesel dynamic pumps. They convert energy into 2 stages, but their work is not actually affected by the purity of the liquid. What kind of fuel pump do you need, only you know!
