1. Product introduction
DZX series plunger metering pump directly sucks or discharges the working medium through the reciprocating motion of the plunger. Since both the plunger and the seal are directly in contact with the medium, selecting a combined plunger material and seal form can ensure that the pump has a better performance during operation
