Hydraulic Gear Pumps
Hydraulic Gear Pumps
WITTE hydraulic gear pumps are used for dosing and transferring hydraulic fluids.
The hydraulic gear pumps of the CHEM series are exclusively designed and assembled in Germany. In addition to pump engineering and design, WITTE offers extensive service packages.
On request, our fitters can also install the pumps directly in the plant and are on site during commissioning. The hydraulic gear pumps of the CHEM series benefit from a comprehensive modular system with a large number of different materials for the individual components.

Hydraulic gear pumps for the chemical industry
In addition to standard chemical pumps, we also supply special pumps according to special customer requirements. We take over the complete engineering as well as the research and development work. We can also carry out test runs close to real operating points on our in-house test bench.
We have already realized special chemical pumps according to customer requirements in a wide variety of designs. For example, ceramic pumps for pumping high-temperature brine working at temperatures above 500 °C. Pumps for extreme design pressures up to 575 bar are also part of our portfolio.
The process is often significantly improved through the use of these pumps. If you have any questions regarding the development of special pumps or the use of special materials, please contact our materials expert and sales manager Mr. Carsten Pump.
