The Voith Contaminex™ CM30-16 GR is a heavy-duty trash pump used in paper mill stock preparation systems, specifically for pumping highly contaminated pulp stock containing ropes, plastics, wire, and other coarse rejects without plugging. It is commonly installed between pulpers and detrashing equipment such as TwinPulp and PreClean systems.

Design Features

• Large pump housing minimizes plugging.
• Free-flow impeller with hard-faced leading edges for long wear life.
• Secondary pulping action helps break down contaminants.
• Suitable for intermittent operation using a variable-frequency drive (VFD).
• Designed for highly contaminated recovered-paper systems. 

Typical Applications

• OCC (Old Corrugated Container) pulping systems
• Mixed waste paper processing
• Transfer of pulper junk to detrashing equipment
• TwinPulp and PreClean reject handling systems

About the "16 GR" Designation

The base Voith literature identifies the pump as CM30/31, but the suffix "16 GR" is typically a mill-specific configuration code that may indicate:

• Impeller or rotor version
• Gear ratio or drive arrangement
• Special materials of construction
• Factory order number
