As a new type of conveying machinery, pneumatic pump is the most novel type of pump in China. Using compressed air as the power source, it can absorb all kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids. Let's take a detailed look at the working principle and characteristics of the pneumatic pump.

working principle:

Pneumatic pump is a high-pressure pump that uses gas as a power to push the piston to work, in short, compressed air as the power. Pneumatic pump can provide pulse-free, stable liquid flow, suitable for chromatographic analysis system. The pneumatic amplification pump utilizing the principle of pneumatic amplification can quickly obtain the required high outlet pressure and provide a large output flow, and is especially suitable for packing chromatographic columns by homogenization. The disadvantage of the pneumatic pump is that the volume of the liquid cylinder is large, and it is inconvenient to replace the mobile phase. If two such pumps are not used, gradient elution cannot be achieved.
