Highest Precision for Extreme Conditions: Gear Pumps for Process Industry

Maximum precision, complete process reliability and consistant performance with the toughest conditions

Application

The challenges in the
chemical and process industries

In the chemical industry, precision is not just a question of efficiency: it determines safety, quality, and cost-effectiveness.
Conventional pumps quickly reach their limits, whether due to metering instability, leaks with aggressive media, high maintenance requirements, or unsuitability for highly viscous and temperature-sensitive substances. 

Mahr | MarChem

Our solution:
High-precision gear pumps with global expertise

Our pump technology has proven itself for decades, for example in the production of synthetic fibers:
under high pressure, at high temperatures, and with extremely viscous media. The continuous further development of the
pumps has opened up their use for a growing range of applications. We are now applying our experience and expertise,
as well as the proven precision and robustness of our pumps, to the process and chemical industries.
