Optimizing extrusion processes with reduced heat and required torque and the elimination of surging
MFG in Monroe, NC USA
The Zenith PEP II series are common in extrusion processes. The Zenith gear pump optimizes the extrusion process by allowing the screw to melt and homogenize the polymer. As the pump generates the needed pressure, it relieves the extruder of work; therefore, reducing heat from the shear, lowering the torque required and eliminating surging.
The Pep II pumps are also offered with the Rheoseal. The Rheoseal design includes reverse flights inside the seal chamber, as well as a water channel to cool the polymer and a backup lip seal. The rotating shafts create a mechanical action on the material, which pumps the polymer back into the pump cavity and seals the shaft from the leakage.
Zenith Pumps provides typical drive and control packages, as well as custom systems designed to meet your particular process specifications. Our extensive experience and full engineering capabilities ensure you the best possible solution to your precision extrusion application. Zenith’s standard extrusion control package provides the basic controls for PEP-II pump systems. The drive consists of a motor and reducer mounted on a common base plate, with speed controlled by a Zenith ZVD digital speed controller. A pressure control system regulates the extruder speed and maintains a constant pressure to the pump inlet. A temperature controller regulates the pump’s electric heaters. Other features available include:
Precision gear pumps are an integral part of many manufacturing processes requiring metering, mixing, dispensing, coating, and extruding, where accuracy and uniformity of flow are critical. That’s why manufacturers in industries from manmade fibers and polymers to food and medical devices have relied on Zenith gear pumps since 1926. With high metering accuracy, pulse-free flow, and long wear life across a wide range of fluid and pressure conditions, the Zenith Pumps brand is synonymous with high performance and reliability.
