LNG refueling station submersible pumps are divided into three categories based on size; can they be interchanged?
Thread Content
The submersible pumps commonly used in LNG refueling stations have capacities of 11KW, 15KW, and 19KW – can these three types be used interchangeably?

As for whether a pump can be used, what I mean is the issue of matching the pump’s capacity to the size of the motor. For example, a motor selected for pumping liquefied gas cannot be used for pumping water, as the motor power required in this case is almost twice as high.
It’s because the number of stages of the motors is different. The head of the pump varies; in fact, 11 KW is sufficient – going for a larger capacity isn’t necessarily appropriate.
High-power systems can be paired with low-power systems, but low-power systems cannot be paired with high-power systems.
The power of the secondary pump in ACD is 11 KW, while the power of the fourth-stage pump is 18.5 KW； The power of the low-temperature two-stage pump in Vanzetti, Italy, is 13 KW, while that of the four-stage pump is 22 KW. The maximum flow rate of Italian pumps is 430 lpm, while that of ACD is 340 lpm. Therefore, companies such as Jerry, Furi, and Anrico are now starting to use Italian pumps, which offer high flow rates at low prices.
