Request for selection of pump type
Thread Content
Our department operates a liquefied gas station, where we mainly sell liquefied petroleum gas, propane, and propylene. We would appreciate it if experts could advise us on what type of pump we should use!
What material is being used? What are the requirements regarding temperature, corrosivity, flow rate, head pressure? Is there any presence of particles? What about viscosity? Please provide some information on these basic parameters
Mainly sells liquefied petroleum gas, propane, and propylene, with a flow rate of 100 cubic meters per hour
The temperature is at room temperature; since it is liquefied gas, it has virtually no viscosity
It’s at room temperature; for transportation, centrifugal chemical process pumps are generally used. If unloading is involved, cavitation can occur easily, so positive displacement pumps such as slide pump or compressors should be used for unloading.
Shielded pumps are relatively safe, though they are a bit more expensive.
Although shielded pumps are a bit more expensive, they are safer and have a lower maintenance rate.
Shielded pumps can be used as loading pumps, but they are not suitable for unloading unless there is a significant height difference between the tank truck and the pump. You can choose a liquefied gas pump
