RM's no-O-ring construction removes a specific, real degradation point — O-ring swelling/hardening under chemical attack — rather than just specifying a more chemical-resistant O-ring compound, which matters on caustic soda service where elastomers are a known wear point.
Caustic soda service is exactly where O-rings tend to swell and harden over time — Richter's RM family removes that failure point by design rather than by picking a more resistant O-ring compound, the real reason RM sits at a different reliability tier than a standard PFA-lined mag-drive pump on the same NaOH duty.
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.
