What Are The Main Parts Of The Fuel Dispenser?

Have you ever asked yourself what’s going on when refueling at your favorite gas station? Imagine the intricacies that go into every drop of fuel that enters your fuel tank. This post will satisfy your curiosity since it will uncover the secrets behind the devices that keep our vehicles moving.

The Main Parts of the Fuel Dispenser

The main parts of the fuel dispenser are the gas pump nozzle, fuel dispenser pump, hose, display screen, underground storage tanks, and pumping unit. Each has its function to ensure that there is precise and safe delivery of fuel to vehicles.

Pumping Unit

• Description: It is a combination of the motor and pump that work together to move the fuel from the underground storage tank to the fuel dispenser and eventually to the vehicle.
• Components: Motor, dispenser gas pump, fuel dispenser hose, and gas pump nozzle
• Materials: Typically constructed using durable metal components to withstand operational demands
• Importance: Essential for ensuring the consistent transfer of fuel from storage to the gas dispenser, enabling efficient fueling.

Gas Pump Nozzle

• Description: This is the most recognizable part of the fuel dispenser pump. It serves as the interface between the dispenser and your vehicle.
• Components: Nozzle, trigger mechanism, and flow control features.
• Materials: Made from metal and high-end plastics to endure frequent use and exposure to fuels (either gasoline or diesel).
• Importance: The gas pump nozzle is crucial for safe and precise fuel transfer. It helps prevent spills, ensuring that the fuel reaches your vehicle’s tank.

Fuel Dispenser Hose

• Description: It connects the fuel dispenser nozzle to the main body of the dispenser pump. The hose allows the fuel to flow from the storage tank to the vehicle.
• Components: Reinforced rubber hose with metal fittings.
• Materials: Reinforced rubber, often with a protective outer layer to resist wear, pressure, and chemical exposure.
• Importance: It is vital for maintaining fuel integrity and preventing leaks. Thus, there is safety whenever the refueling process is ongoing.

Fuel Dispenser Pump

• Description: The core component of the gasoline dispenser pump. It is responsible for moving fuel from the underground storage tanks to the vehicle. There are two primary types of dispenser pumps. These are submersible pumps and suction pumps. The former pushes fuel out of the tank while the latter pulls fuel from the tank.
• Components: Motor, pump mechanism, valves, and control systems.
• Materials: This pump is made using robust metal products combined with specialized materials that handle high pressures and corrosive fuels.
• Importance: It ensures the reliable and accurate delivery of fuel, functioning as the heart of the fuel dispensing system.

Flow Meter

• Description: This measures the precise amount of fuel being dispensed to ensure customers receive the correct volume.
• Components: Gears, turbines, and measurement sensors.
• Materials: Made using metal alloys to ensure precision and durability
• Importance: This part is essential because it provides accurate billing and customer satisfaction, as well as regulatory compliance.

Display Screen

• Description: It displays the key information whenever the fuel dispenser pump is in use. These are the amount of fuel dispensed, cost, and price per gallon or liter. Modern fuel dispensers typically use digital displays, which are easier to read. They can also show more detailed information. Some older models may still have mechanical displays.
• Components: LCD or LED screen, control circuitry.
• Materials: Made from glass or durable plastics with electronic components
• Importance: This screen offers transparency and clarity to customers during the fueling process, improving user experience.

Keypad or Touchpad

• Description: This component allows customers and gas station personnel to interact with the fuel dispenser, input payment details, select fuel types, and perform other functions.
• Components: It consists primarily of buttons, a touch-sensitive surface, and an integrated payment system.
• Materials: It is typically made from durable plastic or rubber for the keypad, with electronic components underneath.
• Importance: This component streamlines the fueling process by enabling easy input and control, enhancing the overall efficiency of the system.

Oil Pump

• Description: The oil pump pressurizes and moves fuel from the storage tank to the vehicle, ensuring consistent flow and pressure.
• Components: It is composed of a pump mechanism, motor, and pressure control systems.
• Materials: The oil pump is made of metal alloys that are designed to accommodate high pressures and withstand corrosion.
• Importance: Critical for maintaining proper fuel flow, especially during high-demand situations, ensuring vehicles are refueled quickly and effectively.

Solenoid Valve

• Description: This valve controls fuel flow within the dispenser using an electromagnetic actuator that opens or closes in response to electrical signals.
• Components: Electromagnetic coil, valve body, actuator
• Materials: Constructed from metals and electrical components to ensure durability and reliability.
• Importance: Regulates fuel flow precisely, preventing overflows and ensuring safe operation of the fuel dispenser.

Underground Storage Tanks

• Description: These are large tanks located underground that store fuel safely at gas stations.
• Components: Tank body, venting systems, access points
• Materials: The UTS are generally made from steel or fiberglass-reinforced plastics to prevent leaks and resist corrosion.
• Importance: Essential for storing large quantities of fuel securely, reducing the risk of evaporation and contamination.

While not a direct part of the fuel dispenser, underground storage tanks (USTs) are necessary for storing large quantities of fuel at a gas station. These tanks keep the fuel cool and safe, reducing the risk of evaporation and contamination.

Self-Sealing Oil Gun

• Description: This automatically stops the flow of fuel when the vehicle’s tank is full, preventing overflows.
• Components: Vacuum-operated shut-off mechanism, nozzle, trigger
• Materials: Typically made from metal and durable plastics that ensure longevity and reliability.
• Importance: Enhances safety by preventing fuel spills and overfilling, ensuring a clean and efficient fueling process.

How Does a Gas Station Pump Work?

Now, that you know the components, understanding how they work together is also essential. Such information will help prevent accidents, such as fuel spills or fires, by allowing users to handle the equipment properly.

Step 1: Customer arrives and selects fuel.

• The customer pulls up to the gas station pump and selects the desired fuel grade using the keypad or touchscreen interface.

Step 2: Payment authorization

• The customer authorizes payment. This is done by inserting a card, tapping a contactless payment method, or entering cash prepayment inside the station.

Step 3: Activation of the pump.

• Once payment is authorized, the gas pump is activated. It allows the selected fuel to be dispensed.

Step 4: Fuel drawn from the storage tank.

• The pump begins drawing fuel from the underground storage tanks based on the customer’s selection.

Step 5: Fuel flows through the system.

• The selected fuel travels through the hose towards the nozzle.

Step 6: Customer dispenses fuel.

• The customer inserts the nozzle into their vehicle’s fuel tank. The trigger is squeezed to initiate fueling.

Step 7: Monitoring fuel dispensing.

• As fuel flows into the vehicle’s tank, the display panel updates in real-time to show the amount of fuel dispensed and the cost.

Step 8: Automatic shut-off engages

• When the vehicle’s fuel tank is full, the automatic shut-off mechanism in the nozzle activates. Fuel stops flowing at this point.

Step 9: Customer concludes the transaction.

• The customer places the nozzle back onto the pump and completes the transaction.

Step 10: Fuel reset and return

• Once done, the pump resets. It is ready for the next transaction.
