Metering pumps [CHEM-SP]

Gear pumps for the chemical industry

Metering pumps

Metering pumps are used in different sectors. For example, in fiber production. Synthetic chemical fibers are gaining importance. They are required for many different applications such as textiles, linens, brushes, etc.

WITTE dosing pumps ensure that the polymer melt in the process is transported evenly and reliably to the corresponding locations in the process. A constant flow rate is very important to ensure consistent quality. Media with very low viscosities can be safely and precisely transported in other applications as well. High efficiency and a long life expectancy characterize this series of pumps.
