🏭 Manufacturer Information

Manufacturer: Werner & Pfleiderer / Coperion GmbH
Headquarters: Stuttgart, Germany
Specialization: Coperion (formerly Werner & Pfleiderer) is globally recognized for engineering high-capacity twin screw compounding and extrusion systems for plastics, chemicals, pharmaceuticals, and food industries. The ZSK series is especially known for its modular barrel design and superior torque transmission systems.

📋 Description

The Used Werner Pfleiderer / Coperion ZSK 160 is a high-throughput, twin screw extruder designed for intensive compounding, dispersion, and mixing of polymers and other bulk materials. Featuring 8 modular barrel sections, this system allows precision adaptation to diverse material processes such as plastics, masterbatch, rubber, chemical reactions, or high-viscosity formulations.

This unit is equipped with:

• A 2500 HP General Electric (GE) drive motor for powerful throughput capability

• A gear reducer with oil cooling system for reliable, high-torque performance

• Complete screws and shafts

• Multiple associated spare parts 

The project is identified as Project No. 87-3593, confirming its original engineering and build scope.
