Medium

Gas

See whether the outlet is loaded, if the outlet is directly connected to the atmosphere, you can choose "C series miniature vacuum pump" or "D series dual-purpose micro vacuum pump and compressors"; if it is for application with load at the outlet, then please select "D series dual-purpose micro vacuum pump and compressors"

Gas and solid impurities mixture 

Solid impurities entering the pump cavity will damage the diaphragm and one-way valve of the micro pump. A filter must be added to the air inlet to filter out the solid impurities, and the filter should be replaced regularly

>>Special filter for micro pump

Liquid

 "S Series Miniature Vacuum Liquid Pump" can be used to transfer liquid

2.Chemical composition of medium

Air and non-corrosive gas

Our air pump products are suitable for air, common non-corrosive gases, and have good chemical resistance

>> Chemical Resistance Performance Table of EPDM

>>Chemical Resistance Performance Table of Reinforced Nylon

Corrosive gas

Most of the pump bodies of our products are made of reinforced nylon, and the diaphragm and one-way valve are made of EPDM rubber, which has good resistance to common corrosive gases. For specific corrosive media or whether chemical reactions occur, please refer to the link Chemical Resistance Performance table. For low-concentration corrosive gas or weak chemical reaction gas or chemical composition not listed in the table, it can be confirmed by actual tests

Flammable and explosive gas

Our products do not have explosion-proof certification and cannot be used in flammable and explosive working environments

Pure water and non-corrosive liquids

Our air pump products are suitable for water and common non-corrosive liquids with good chemical resistance

>>S Series Miniature Vacuum Liquid Pump Model List

Corrosive liquid

Most of the pump bodies of our products are made of reinforced nylon, and the diaphragm and one-way valve are made of EPDM rubber, which has good resistance to common corrosive liquids. Whether it can withstand specific corrosive media or whether chemical reactions occur, please refer to the link Chemical Resistance Performance table. For low-concentration corrosive gas or weak chemical reaction liquid or chemical composition not listed in the table, it can be confirmed by actual tests.
