Abstract
The plunger pump with air tube is a kind of plunger pump specially designed for transferring residual paste particulate medium.Compared with other plunger pumps,this pump has an additional fluid input valve and an air tube,taking the residual paste articulates medium from trunk piston cavity with the help of clean medium,which enables the trunk piston and piston seal to work in an environment of clean medium,so that the service lifetime and operating pressure of the pump are increased,while the manufacturing cost is lowered.
