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.工作壓力和流量

1. Working pressure and flow rate

工作壓力參照驅動氣壓為0.48Mpa時泵輸出壓力和流量。如果泵的輸出壓力大于所需的工作壓力，這就要考慮措施。

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.驅動氣體的壓力和流量

2. Pressure and flow rate of driving gas

在連續工作時使用的驅動氣壓不超過0.69Mpa，在間歇工作時可達到1.03Mpa。在很好性能狀態時氣動泵的耗氣量，請參照所需驅動氣體流量表。

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.輸送液體介質

3. Conveying liquid medium

泵輸送的液體介質是氣動增壓泵的選型中著重考慮的部分。液壓部分的材質和液壓密封圈是由輸送的液體介質所決定的。泵可用油、水和大多數液體介質。標準泵的主要液壓密封圈是丁橡膠和聚氨酯，單向閥座采用特氟龍密封。其它密封材料包括碳氟化合物和亞乙基丙烯，這些密封材料主要用于輸送的特殊介質。請向工廠或當地的分銷商咨詢密封材料選型。

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.可接受的體積和重量對于某些的應用，氣動增壓泵和動力單元的外形尺寸和重量也要考慮。

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.

氣動增壓泵就能夠保證這幾項參數的標準達到給我們使用帶來方便的情況，這樣就從根本上保證了起動增壓泵的工作效率。

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.
