For mini plant and microreaction technology

The mzr-6355 micro annular gear pump of the hermetic and chemically inert series is, considering its almost universal suitability for aggressive and corrosive liquids, a revolution in the pump technology. Its rotors and functional elements being made of ceramics, the pump shows the highest chemical resistance and an outstanding resistance to wear. Thanks to the use of SSiC (pressureless sintered silicon carbide) as bearing and shaft material, a magnetic coupling, and case components made out of alloy C22 (DIN 2.4602), this pump will take up any challenge in the chemical industry applications.
