Booster Pumps
Booster Pumps
WITTE booster pumps are used to build up the required process pressure in polymer production. Due to their robust design, these pumps are ideally suited to generate high pressures in conveying processes. Mainly pumps of this type convey polymer melts with high viscosities. Installation can be horizontal or vertical.
Conversion service for booster pumps and high-pressure pumps:
We also rebuild existing makes of other manufacturers according to your wishes. We can fall back on a wide range of shafts, bearings and seals in various materials. Many of the parts are available in our bearings in Germany, USA and China.

Special pump construction for booster pumps
High pressure pumps of the BOOSTER series are used in polymer production to build up the required process pressure. Our BOOSTER pumps are available in round or square designs. On customer request we modify the pumps so that they can be installed as replacement pumps in the same dimensions, but with increased throughput, at the same location in the plant: A conversion of reactors, pipes or flange connections is not necessary. Special designs according to customer requirements are also possible.
