The Witte rubber compounding pump is designed and manufactured for rubber processing.
This pump type is specially developed for rubber processing and rubber compounding.
Most rubber compounds are very sensitive to heat. This requires a pump that limits the temperature increase to a minimum.
The pump can be executed with housing, shaft and even bearing cooling.
The addition of a gear pump to the rubber compounding line makes it possible to reduce the overal temperature in the system.
This reduces degradationand possible vulcanisation of the rubber product.
Examples of rubber compounds: EPDM, CR, NR, NBR, SBR, NR FPM, BR…
The use of a gear pump in the rubber compounding line has several advantages.
