There are two common valve pump and valveless pump. Plunger metering pump because of its simple structure and high temperature and pressure and other advantages have been widely used in the field of petrochemicals. Aiming at the shortage of high-pressure medium under the condition of high pressure, the valve-less rotary plunger metering pump has been paid more and more attention. It is widely used in high viscosity medium such as syrup, chocolate and oil additives Metering added. Due to the structural disadvantage of being unable to achieve complete isolation between the metering medium and the pump lubricant, the plunger metering pump suffers from a number of limitations in high contamination prevention fluid metering applications.
