To ensure quality and repeatability‚ producers must control extruder variations such as pressure fluctuations‚ viscosity inconsistencies and density changes.

With the Zenith PEP II gear pump‚ manufactures can effectively control the melt delivery to the downstream equipment ensuring a final product that is reliable‚ repeatable and economical. To achieve this control‚ the PEP II series regulates the back pressure on the extruder minimizing resident time and stabilizing the plasticizing action of the extruder.
