Richter Chemie-Technik
Sealless magnetic-drive centrifugal pumps and PTFE/PFA-lined valves for aggressive chemical service — German-engineered, ENVIPACK maintenance-free stem sealing.
Richter Chemie-Technik makes sealless magnetic-drive centrifugal pumps (MNK, MPB, QMD, RM) and PTFE/PFA-lined valves for aggressive chemical service. MNK and RM use an eddy-current-free CFRP/PTFE containment can; MPB self-primes and handles up to 30% gas content. Ball valves use ENVIPACK maintenance-free stem sealing, and the NK butterfly valve reaches DN1000 (40 inch).
What LibertyCES specifies from Richter Chemie-Technik
Eddy-current-free CFRP/PTFE containment can and rare-earth SmCo/NdFeB magnets — MPB tolerates up to 30% gas content, RM requires no O-rings.
ENVIPACK maintenance-free self-adjusting stem seal standard across the entire ball valve range, DIN EN ISO 15848-1 + SIL certified.
NK reaches DN1000 (40") — the widest size range of any Richter valve — with triple stem sealing and PFA disc + PTFE body lining.

Frequently Asked Questions
What makes Richter magnetic drive pumps energy-efficient?
The MNK and RM families use an eddy-current-free CFRP/PTFE composite containment can instead of the standard metal can most mag-drive pumps use, avoiding the wasted energy and heat that eddy-current losses generate as the drive magnet rotates.
Which Richter pump handles gas-laden liquids?
The MPB Peripheral Magnetic Drive Pump safely pumps liquids with up to 30% gas content and is self-priming without an additional suction tank — a real, distinct capability the other three centrifugal families are not designed for.
Is there a Richter valve rated specifically for chlorine service?
The RSS bellows-sealed control valve carries an explicit "Chlor application: special design for particularly long service life" claim, with thick-walled PFA lining for maximum permeation resistance.
Does Richter serve semiconductor and high-purity applications?
Yes — Richter's own spec table lists a dedicated Semi-Conductor/Photovoltaic sector for high-purity and ultra-high-purity water, pure chemicals, and acids. See LibertyCES's semiconductor & high-purity manufacturing page for the full manufacturer cluster.
