What is the medium used for pressurization?
For liquids such as clean water, hydraulic oil, aviation kerosene, emulsion, etc., choose a gas-liquid booster pump. For gases such as air, nitrogen, oxygen, helium, etc., choose a gas booster pump. Although the principle is the same, the two types of pumps have different structures, so they cannot be mixed.
2. What is the pressure before being pressurized by the pressurized medium?
For gas-liquid booster pumps, the liquid source does not require pressure and relies on the pump's self priming ability to suck the medium into the pump for pressurization; For gas booster pumps, it is necessary to know the inlet pressure of the medium, which is crucial for the correct selection. If the output pressure is above 8MPa and the inlet pressure is less than 1.2MPa, the two-stage gas booster pump HGT series needs to be selected. For HGS series and HGD series with a boost ratio of 10:1 or above, the inlet gas must have a high pre pressure, such as nitrogen gas cylinders.
3. What is the temperature of the pressurized medium?
Pneumatic booster pumps are generally not suitable for boosting high-temperature fluids.
If it is a pressure test, what is the volume of the product being compressed?
If there is no specific data available, you can choose common volumes that are relatively equal for description, but do not inform. Words such as "not big" or "very small" are not helpful for selection as size is a relative concept
