The sampling pump is mainly used for sample collection of gas or liquid, and thus can be divided into a gas sampling pump and a liquid sampling pump according to the working medium. Since the sampling pump is a sample collection, its volume is very small, and we usually call it a micro vacuum pump.
The DP16147 series diaphragm type electromagnetic pump is suitable for gas sampling and can be used with various analytical instruments. It can also be used in other applications with similar conditions and requirements.
DP16147 series diaphragm type electromagnetic pump absorbs the characteristics of similar foreign products, and has the characteristics of small size, light weight, stable flow, low noise, and long-term non-stop operation. Users can choose different models according to the conditions of use, and can use multiple pumps in parallel to broaden the scope of use.
The basic principle of the sampling pump: the circular motion of the motor, the diaphragm inside the pump is reciprocated by mechanical means, so that the volume in the pump chamber of the fixed volume is compressed and stretched to form a vacuum (negative pressure), at the pumping port At a pressure difference from the outside atmospheric pressure, the gas or liquid is pressed (sucked) into the pump chamber by the pressure difference, and then discharged from the exhaust port.
