The pneumatic booster pump is a plunger pump controlled by a two position four way pilot valve for reciprocating motion. Using gas pressure to transmit energy, the pneumatic device has a simple and lightweight structure, easy installation and maintenance, and the medium is air, which is less flammable compared to hydraulic medium. Therefore, it is used. When choosing a pneumatic booster pump, multiple considerations should be taken into account to ensure that the standards for these parameters meet the requirements that bring convenience to our use, thus fundamentally ensuring work efficiency. Choosing a pneumatic booster pump should consider the following aspects:

1.工作压力和流量

1. Working pressure and flow rate

工作压力参照驱动气压为0.48Mpa时泵输出压力和流量。如果泵的输出压力大于所需的工作压力，这就要考虑措施。

The working pressure refers to the pump output pressure and flow rate when the driving air pressure is 0.48Mpa. If the output pressure of the pump is greater than the required working pressure, measures should be considered.

2.驱动气体的压力和流量

2. Pressure and flow rate of driving gas

在连续工作时使用的驱动气压不超过0.69Mpa，在间歇工作时可达到1.03Mpa。在很好性能状态时气动泵的耗气量，请参照所需驱动气体流量表。

The driving air pressure used during continuous operation does not exceed 0.69Mpa, and can reach 1.03Mpa during intermittent operation. Please refer to the required driving gas flow rate table for the air consumption of the pneumatic pump in good performance state.

3.输送液体介质

3. Conveying liquid medium

泵输送的液体介质是气动增压泵的选型中着重考虑的部分。液压部分的材质和液压密封圈是由输送的液体介质所决定的。泵可用油、水和大多数液体介质。标准泵的主要液压密封圈是丁橡胶和聚氨酯，单向阀座采用特氟龙密封。其它密封材料包括碳氟化合物和亚乙基丙烯，这些密封材料主要用于输送的特殊介质。请向工厂或当地的分销商咨询密封材料选型。

The liquid medium conveyed by the pump is a key consideration in the selection of pneumatic booster pumps. The material and hydraulic sealing ring of the hydraulic part are determined by the liquid medium conveyed. Pumps can be used with oil, water, and most liquid media. The main hydraulic sealing rings of the standard pump are neoprene and polyurethane, and the one-way valve seat is sealed with Teflon. Other sealing materials include fluorocarbon compounds and ethylenepropylene, which are mainly used for conveying special media. Please consult the factory or local distributor for sealing material selection.

4.可接受的体积和重量对于某些的应用，气动增压泵和动力单元的外形尺寸和重量也要考虑。

4. Acceptable volume and weight For certain applications, the external dimensions and weight of pneumatic booster pumps and power units should also be given special consideration.

气动增压泵就能够保证这几项参数的标准达到给我们使用带来方便的情况，这样就从根本上保证了起动增压泵的工作效率。

The pneumatic booster pump can ensure that these parameters meet the standards and bring convenience to our use, thus fundamentally ensuring the working efficiency of the starting booster pump.
