Gas stations, as crucial nodes in modern transportation, the choice of equipment directly affects efficiency, safety and cost. If you are involved in the construction or upgrading of gas stations, you may notice a notable trend: over 90% of newly built gas stations have chosen submersible pumps (submersible pumps) as the core oil transportation equipment. What is the reason that has made submersible pumps almost become the "standard equipment" for newly built gas stations?
Closed operation: The submersible pump operates completely submerged in the oil in the tank. The motor and pump body are all below the oil, and the pumping process is completed entirely within a closed pipeline.
Eliminating leakage points: Unlike self-priming pumps which need to be installed on the ground and draw oil from the tank through negative pressure, submersible pumps have no exposed suction pipelines or joints, fundamentally eliminating the possibility of oil or gas leaking from these connection points. This significantly reduces the risks of fire and environmental pollution.
Compliance with strict regulations: The safety and environmental protection regulations for modern gas stations are becoming increasingly stringent. The sealing performance of the submersible pump is the most reliable way to meet these regulations.
Positive pressure push: The submersible oil pump is located at the bottom of the oil tank and directly "pushes" the oil towards the fuel dispenser. There is no need to painstakingly create a vacuum (draw air) in the suction pipeline like a self-priming pump does first.
Quick start-up and stable flow rate: Oil comes out almost instantly when refueling, and the oil flow is more stable, less likely to cause gas blockage (especially at high flow rates or high oil temperatures). Drivers no longer need to wait, which greatly enhances the user experience.
Strong adaptability: It has fewer restrictions on the burial depth of the oil tank and the distance of the fuel dispenser, and the design layout is more flexible.
Simple structure and low failure rate: The main components of the submersible pump (motor and pump) are integrated in the oil tank, while the ground part only consists of the control box and pipelines, making its structure relatively simple. There are no exposed and vulnerable components like rotating seals.
Easy to maintain: Although the oil tank needs to be lifted to the well for maintenance, the frequency and difficulty are usually lower than inspecting the complex leakage points or gas resistance issues in the self-priming pump suction pipeline.
Long service life: The oil has a certain cooling and lubricating effect on the submersible pump motor. With reasonable use and maintenance, its service life is relatively long.
Fully sealed system: From the oil tank to the fuel nozzle, the entire transportation process takes place under positive pressure and within a sealed pipeline.
Reduce leakage: Compared with the self-suction pump system which may have negative pressure sections causing trace amounts of oil and gas to escape, the submersible pump system can better cooperate with the oil vapor recovery device, more effectively control the oil and gas volatilization (VOCs) during the operation of the gas station, and is conducive to environmental protection.
The motor of the submersible pump is submerged in the oil, effectively isolating and absorbing the running noise. The pump's operation is hardly audible on the ground, being much quieter than the self-priming pumps installed on the surface, thereby reducing noise interference for the station staff and the surrounding environment.
The submersible pump, with its outstanding safety, efficient operation performance, low maintenance requirements and excellent environmental protection features, perfectly meets the strict demands of modern gas stations for safety, efficiency, environmental protection and user experience. This is not merely a technological upgrade, but rather an inevitable choice for the gas station industry to move towards greater safety, higher efficiency and more environmental friendliness. Therefore, the phenomenon of "90% of new gas stations choosing the submersible pump" is the natural result of the market's selection of the optimal solution. Next time you fill up your tank, think about it: it is this "invisible" submersible pump underground that is silently ensuring your fast and safe fueling experience.
