Request a Spec Review →Named chemicals
LibertyCES has documented Sealless Pump in Oxidizers/Disinfectants service, including Sodium Hypochlorite, Peracetic Acid and Bromine. Wetted materials to confirm: PFA, PTFE and conductive PFA. Documented models include Richter MNK/RM Series. Compatibility depends on exact concentration, temperature and duty cycle, so confirm with a free spec review.
Notes from the vendor documentation
Richter Industries page explicitly names Bromine Production, sodium hypochlorite, and PAA in F&B CIP context for its sealless mag-drive line.

Real Specifications
| Spec | Value | Source document |
|---|---|---|
| Richter F&B CIP named chemicals | Caustic Soda, Phosphoric Acid, Nitric Acid, Sodium Hypochlorite, Peracetic Acid named directly as CIP process chemicals | Richter Chemie-Technik — Industries + Centrifugal Magnetic Drive Pumps |
| Richter Base Chemicals named application | Bromine Production named directly under Base Chemicals | Richter Chemie-Technik — Industries + Centrifugal Magnetic Drive Pumps |
| MNK lining options | PFA, PTFE, or PFA-conductive lining options | Richter Chemie-Technik — Industries + Centrifugal Magnetic Drive Pumps |
| MPB gas tolerance | MPB self-primes without an additional suction tank and safely pumps liquids with up to 30% gas content — a capability the other 3 Richter families do not share | Richter Chemie-Technik — Industries + Centrifugal Magnetic Drive Pumps |
Richter's own documentation: MNK, RM, and QMD are not gas-tolerant by design — only MPB safely handles liquids with up to 30% entrained gas content, so specifying MNK or RM on an actively off-gassing oxidizer stream risks the cavitation-driven failure MPB exists to avoid.
Sodium hypochlorite off-gasses in the line, and Richter's own four-family lineup gives real gas tolerance to only one of them — MPB, rated up to 30% entrained gas — so specifying MNK or RM on an actively off-gassing oxidizer duty risks the exact cavitation failure MPB was built to avoid.
Every material and product claim on this page traces to real, vendor-published documentation on file with LibertyCES. Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.
