Zenith PEP II Series
Gear Metering Pump
Type: Positive Displacement Pumps
Designs: Mechanically Sealed / Metering Gear
Manufacturer: Zenith
Product Description
While gear-pump-assisted extrusion has been used for years, the Zenith PEP II positive displacement pump optimizes the process by allowing the screw to melt and homogenize the polymer. This means the extruder isn’t pushed as hard so there’s less heat from the shear, which means less torque and no surging.
The PEP II pumps can also come fitted with the Rheoseal. The Rheoseal provides a water channel to cool the polymer as well as reverse flights inside the chamber. The pump’s improved dimensional stability and controlled melt quality isolates the die from upstream fluctuations and stabilizes the plasticating action while lowering melt temperature. The PEP II also provides extended extruder life and a lower cost to operate.
