Introduction
The LNG cryogenic pump lever is the "heart" of the LNG refueling station, responsible for boosting LNG and delivering it to the refueling machine. Single pump pry refers to the integrated pry block equipped with only one low-temperature submersible pump.

Main advantages
|
Lowest initial investment cost: |
Only one main pump and related pipeline valves are configured, and the equipment procurement cost is significantly lower than that of a double pump pry, making it the preferred choice for the most cost sensitive construction project. |
|
Simple structure and compact footprint: |
The number of equipment components and process pipelines is small, the size of the pry body is small, and the footprint is smaller, making it easy to arrange in stations with limited space, especially in pry stations. |
|
Easy operation and maintenance, with few fault points: |
A single system means lower workload and cost for daily inspections and maintenance. The electrical control logic is also relatively simple, reducing the technical threshold and risk of misoperation for operators. |
|
Relatively low energy consumption: |
Only one pump is running, which results in lower total energy consumption compared to a dual pump system (which may require pre cooling or circulation of the backup pump). |
