Polymer Gear Pumps
Polymer Gear Pumps
The polymer gear pumps of the BOOSTER and POLY series are perfectly matched to each other and are therefore perfectly suited for use in the various process stages. They complement each other through their perfectly matched properties. This makes them predestined for use in the production of prepolymers and polymers.
Monomers and thermoplastics also benefit from the gentle pumping of these pumps. Polymer gear pumps of these series are used, for example, in one of the world's largest PA production plants.
- Polymer gear pumps with viscosities up to 40,000 Pas

Conversion service for polymer gear pumps:
Other makes of gear pumps from other manufacturers are rebuilt in our workshops and equipped with higher quality and more durable shafts, bearings and seals. This allows throughputs to be increased and maintenance intervals to be extended. A cost-intensive new acquisition can thus be avoided. We can supply these spare parts for many makes of other well-known manufacturers. Especially for large discharge pumps, retrofitting can lead to significant improvements in the process and the end product.

Special pump construction for the polymer industry
We can offer our discharge pumps in different versions, with square or round inlet or with shortened inlet flange. Alternatively, we also develop solutions that are exactly adapted to the system and the installation situation. Modified versions with the same footprint and double throughput are already in use at many customers. Here we can also consider the dimensions of a third-party product and replace it with a modified WITTE version.
