Richter Magnetic Drive Chemical Process Pump - PFA PTFE Lined Sealless

Richter Magnetic Drive Chemical Process Pumps

Richter Magnetic Drive Chemical Process Pumps are fluoroplastic-lined, sealless centrifugal pumps designed for the safe and efficient transfer of corrosive, toxic, and hazardous chemicals. Available in three duty classes — MNK (heavy duty), RM (medium duty), and QMD (standard duty) — these pumps use permanent magnet coupling to eliminate mechanical seals entirely, achieving zero fugitive emissions. With PFA, PTFE, or FEP lining and an eddy-current-free CFRP/PTFE containment shell, they deliver exceptional chemical resistance and energy efficiency.

Manufactured by Richter Chemie-Technik GmbH, Germany, with over 65 years of expertise in fluoroplastic-lined equipment, these pumps feature the proprietary SAFEGLIDE PLUS dry-running optimized SSiC bearings and SmCo/NdFeB permanent magnets. The sealless magnetic drive design eliminates all seal-related maintenance, leakage risks, and environmental compliance concerns, making them the safest choice for handling aggressive acids, caustics, solvents, and hazardous chemicals in chemical processing, pharmaceutical, semiconductor, and other critical industries.

Frequently Asked Questions

What is a magnetic drive chemical process pump?

A magnetic drive chemical process pump is a sealless centrifugal pump that uses permanent magnets to transmit torque from the motor to the impeller through a containment shell, eliminating the need for mechanical seals. This prevents any leakage of hazardous or corrosive fluids to the atmosphere.

The MNK series is heavy duty rated for -60°C to +200°C with PFA/PTFE lining and the widest size range (DN 25 to DN 200). The RM series is medium duty for -30°C to +150°C with PFA lining. The QMD series is standard duty for -10°C to +100°C with FEP lining, offering an economical option for less demanding applications.

Richter magnetic drive pumps are available with PFA (perfluoroalkoxy), PTFE (polytetrafluoroethylene), conductive PFA for ATEX applications, and FEP (fluorinated ethylene propylene) lining. All fluoroplastic linings provide exceptional chemical resistance to virtually all corrosive media.

SAFEGLIDE PLUS is Richter's proprietary dry-running optimized bearing system made of sintered silicon carbide (SSiC). It provides enhanced protection against dry running conditions, extending pump life and reducing the risk of bearing failure during process upsets.

The CFRP/PTFE eddy-current-free containment shell eliminates energy losses caused by eddy currents in metallic containment shells. This results in higher efficiency, lower operating temperatures, and reduced energy consumption compared to metallic containment designs.
