Gear Metering Pumps
Gear Metering Pumps
WITTE gear metering pumps work with viscosities from 0.5 to 1000000 mPas and are preferably used in the chemical industry. A wide range of media can be conveyed using different material combinations.
- Gear metering pumps of the CHEM series are extremely flexible in design and can be offered in various variants and configurations thanks to a modular system.
- Gear metering pump for differential pressures up to 120 bar, suction pressures vacuum up to 15 bar
- Gear metering pump for temperatures up to max. 500 °C in combination with a magnetic coupling.
- Gear metering pump for viscosities up to 1,000,000 mPas or higher.
- Gear metering pump made of stainless steel, ceramics and special materials
- Gear metering pump with throughput from 20 l/h to 170,000 l/h
The CHEM series is suitable for low viscosities with high pressures while the BOOSTER, EXTRU and POLY series are used for viscous melts. WITTE offers a comprehensive service for all gear pumps, from consultation, planning and design of the pumps to commissioning on site.

Gear metering pumps in special pump design
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 degrees Celsius.
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.
