Hydraulic Pumps
Pumps for hydraulic applications
WITTE hydraulic pumps are pumps of the CHEM series and are adapted to the requirements of the respective process. For example, WITTE has built a hydraulic pump that was needed to circulate hydraulic fluid for use in an offshore process.
Various sealing variants are available for hydraulic pumps. Depending on the pressure conditions, magnetic couplings can also be offered for these pumps.
- Hydraulic pump for viscosities up to 4000 mPas
- WITTE hydraulic pumps are pumps of the CHEM series and are adapted to the requirements of the respective process.
- For example, WITTE has built a hydraulic pump that can circulate hydraulic fluid for use in an offshore hydraulic pump with flow rates from 35 l/min to 90 l/min.

Hydraulic pumps for use in the chemical industry
In addition to standard chemical pumps, we also supply hydraulic 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 at 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 hydraulic pumps for pumping high-temperature brine operating at temperatures above 500 degrees.
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 hydraulic 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.
