Pressure Pumps
Pressure Pumps
WITTE gear pumps of the BOOSTER series provide the required process pressure in the systems. The pressure pumps impress with their extremely robust design and thus guarantee precise and reliable pressure build-up.
- Pressure pumps for differential pressures up to 250 bar
- Pressure pumps with suction pressures from vacuum to max. 120 bar
- Pressure pumps for viscosities up to 40,000 Pas
- Pressure pumps with flow rates from 10 kg/h to 30,000 kg/h
- Pressure pumps with delivery volumes from 4.7 ccm/U to 12,000 ccm/U
- Pressure pumps for processing polymers
These BOOSTER pumps can play off their advantages perfectly, especially when processing highly viscous polymer melts. A wide range of special materials is available for particularly demanding media with corrosive or abrasive properties. The pumps can thus be matched precisely to the application and case of application, thus achieving long service lives and optimum efficiencies.
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 pressure 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. At the customer's request, we can modify the pumps so that they can be installed in the same place in the system as replacement pumps with identical dimensions but increased throughput. A conversion of reactors, pipes or flange connections is not necessary. Special designs according to customer requirements are also possible.
