PEP-II Series Gear Pump
Brand: Zenith Pumps.PNG)
The PEP-II’s unique positive displacement design provides consistent, accurate polymer delivery under varying extruder output conditions of pressure, temperature and viscosity. With the PEP-II providing the pressure between the extruder and the die, extruder parameters can be configured to provide a homogeneous melt at increased throughputs and tighter gauge tolerances.
Today, the Zenith PEP-II pump has become the pump of choice for a wide range of polymer applications in the plastics industry. Zenith can be found wherever precise, pulseless, repeatable metering of fluids is required.
Features- Improved Dimensional Stability - Effectively isolates the die from upstream fluctuations
- Controlled Melt Quality - Regulates the extruder back pressure while it reduces residence time, stabilizes the plasticating action, and lowers melt temperature
- Increased Production - Provides very high efficiency regardless of its pressure building requirement
- Reduced Raw Material Usage - Provides a narrower finished product gauge variation
- Eliminates Surging and Screw Beat - Effectively handles problems caused by melt density or extruder parameters
- Increased Extruder Flexibility - Allows varying process conditions such as higher regrind levels, temperatures, pressures, etc.
- Crowned Root Gear Design - Reduces shear internal to the pump, lowering the temperature and increasing the production rate per power required
- Streamlined Operation and Startup - Closed-loop controls provide easy operator interface
- Extended Extruder Life - Reduces work required by the extruder such as pressure and torque
- Lower Operational Costs - Provides a more efficient method of conveying, eliminating material giveaway, and increasing production per pound of extrudate, etc.
