Fields of application Corrosive, environmentally critical and high-purity fluids in the chemical, pharmaceutical, petrochemical, semiconductor, pulp, metal, food processing and waste disposal/recycling industries. The RMI (ISO/DIN) and RMA (ASME/ANSI) series were developed • for use with media where stainless steel and conventional polymers such as PE, PP etc. do not have sufficient corrosion resistance • as an alternative to - pumps made of expensive long-lead-time metals (Alloy C, titanium, nickel, etc.) - mechanical seal pumps - full polymer pumps - metal pumps with double mechanical seals and...

© Sturdy design for dimensional stability even at high temperatures • Full-surface ductile cast iron EN-JS 1049/ASTM A395 allows for higher pump pressure and temperature rating than an all plastic pump • Impeller magnet assembly provides stable metal core • Highest grade SSiC silicon carbide sleeve bearing system for resistance of chemical abrasion and corrosion © Non-metallic double can system • Wetted: thick-walled pure PTFE • Pressure-bearing: carbon-fibre, with high safety reserves • No eddy currents: no heating of fluid, no energy waste © High-performance NdFeB (neodymium iron boron) and...

Other Richter process pumps Richter magnetic drive and mechanical seal pumps are used - just like Richter chemical shut-off, control and safety valves - in different chemical and related processes. This pump range also includes more specialised designs. The plant operator can thus choose from Richter pumps even for very difficult applications. Mechanical seal pumps • to DIN/EN 22858/ISO 2858 up to 300 m3/h (1320 USgpm) and 90 m (300 ft) LC • to ASME B73.1 up to 115 m3/h (300 ft) and 105 m (350 ft) LC Self-priming pumps for emptying containers and basins from the top. Suction height up to 6 m...
