Hello everyone, I am Mr Liu from Walkedsea International Freight, today I would like to talk about how to classify liquid discharge pumps.

What is a drain pump? Why is it called positive displacement pump? How do you classify it?

Liquid discharge pump, also known as positive displacement pump, positive displacement pump, refers to the reciprocating or rotating movement of the working element in the pump cylinder, so that the working volume alternately increases and decreases to achieve the suction and discharge of liquid pump. Because the flow of the discharged liquid is proportional to the frequency of the volume change, it is called a positive displacement pump.

According to the working mode of the moving parts can be divided into reciprocating pump and rotary pump. Discharge pumps are included in the related subhead under head 84.13.
