Types of electrical fuel pumps for various applications

Every vehicle’s heart is its fuel and exhaust system, and fuel pumps are the most important components of this system. There are various types of fuel pumps used in various applications. Because these pumps supply fuel to various parts of the engine, it might stop working if some of these pumps stop performing. Let’s take a look at some types of fuel pumps used in various applications.

Roller vane pumps

Roller vane pumps consist of a rotor fitted with metal rollers. These rollers create a vacuum which pulls the fuel into the pump. Once the fuel enters the pump, the rollers force the fuel out of the pump chamber with extreme pressure. These types of pumps are popularly used in applications which involve multiport fuel injection. No other type of pump can handle fuel contaminants as much as Roller vane pumps. They are also used in transferring non-abrasive liquids and aromatic solvents.

Turbine pumps

Turbine pumps consist of a turbine blade which operates at a high speed. When the fuel enters the blade chamber, the spinning blade forces the fuel towards the pump’s outlet with great pressure. Turbine pumps are used in various applications to transfer hot fuel from one point to another. They offer high efficiency and reliability, so they are used to supply fuel in gasoline and other fuel engines. However, these pumps are sensitive to fuel contamination.

Gerotor pump

It is a gear drive pump which consists of two gears; a smaller gear and a larger outer gear. When the gears start rotating, they create a vacuum which draws the fuel into the pump. They also create contraction which pressurizes the fuel to move out of the pump. Gerotor pump is used by auto makers’ like- Chrysler and Ford in their vehicles which involve multi port fuel injection system. This type of pump is used in transferring hydraulic fluid, lube oil and light fuel oils.

Solenoid pumps

Solenoid pumps are mostly used to transfer fuel from the vehicle’s fuel tank to its engine. The pump consists of an electromagnetic coil and a piston; there is no motor or blade used in it. Solenoid pumps are manufactured as per requirement with different pressure ranges. The pumps are long lasting and durable as they do not contain bellows or rubber parts.

Peripheral pumps

Peripheral pumps are used to transfer fuel from motor vehicle’s fuel tank to the vehicle’s internal combustion engine. Its internal structure consists of a fuel delivery duct, a fuel intake duct and rotor blade.

Brush-less pumps

Brush less pumps consist of a three phase motor which is completely brushless. Brush-less pumps can easily work with gerotor and turbine pumping sections. They can be used to transfer or pump bio diesel fuel, pump diesel, gasoline-ethanol blend, automotive gasoline, etc. The pumps offer reduced power consumption, durability, high efficiency, and compatibility with wide range if harsh fuels.

According to confirmed reports, using Brushless fuel pumps reduces the power consumption by 36 per cent. This can help auto makers in reduction of CO2 emissions and also help in offering fuel economy improvement in vehicles.
