Why Gas Stations Choose Submersible Pump Fuel Dispensers
Since the 1970s, submersible pump systems have gained popularity over self-priming pumps, with major oil companies worldwide adopting this technology. Currently, around one million gas stations across the globe use submersible pumps, with more than half of these stations opting for positive-pressure fuel delivery systems. The shift from self-priming pumps to submersible pumps is primarily driven by the need for more efficient, flexible, and reliable fuel distribution.

Working principle of submersible pump
The submersible oil pump is connected with the oil tank, and the oil in the oil tank is transported to the fuel dispenser by using the impeller, eddy current and pressure change inside the submersible pump.
Main features of submersible pump:
Suitable for long-distance refueling.
The maximum pumping distance of the self-priming pump is about 50 meters, which cannot meet the longer refueling operations. Therefore, combined with the current requirements, when the structural conditions of the fuel dispenser are 106 meters from the tanks, 6 meters from the tank to the suction system, the suction pump cannot suck the oil in the tank to the fuel dispenser.
At this time, only the submersible pump can meet the current requirements and complete the long-distance refueling work. In order to ensure efficient and reliable refueling operations, it is recommended to use a submersible pump to complete the refueling operation.
Cost saving:
First of all, submersible pump can supply oil to multiple fuel dispensers, saving pipeline, elbow, bottom valve and other accessories, reducing the construction cost of fuel station.
Secondly, the user does not need to have complex professional skills and operational experience, but only needs to operate according to the standard of the refueling interface, thus reducing the cost and difficulty of use.
Moreover, the submersible pump is very convenient to maintain and can be solved by simple debugging and replacement of parts, thus reducing maintenance costs and time.
Finally, the submersible pump adopts advanced hydraulic system and electronic control system, has a high oil transmission speed and flow, can quickly complete the refueling operation, effectively improve the work efficiency and reduce fuel consumption, so as to achieve the purpose of energy saving.
