Real Specifications
| QMD temperature range | -10°C to +100°C (14°F to +210°F) — narrowest range of the 4 families, positioned as the economical/standard-duty tier | richter-ct-magnetic-drive-pumps.md |
| RM sealing detail | RM does not require O-rings — a distinct sealing-philosophy differentiator from MNK's PFA/PTFE/PFA-conductive lining options | richter-ct-magnetic-drive-pumps.md |
| Shared housing/magnet materials | EN-JS 1049 / ASTM A 395 ductile iron housing; magnetic coupling uses SmCo and NdFeB rare-earth permanent magnets | richter-ct-magnetic-drive-pumps.md |
| Certifications | MNK/MPB/RM certified to 2006/42/EC (Machinery Directive) and 2014/34/EU (ATEX) | richter-ct-magnetic-drive-pumps.md |
Richter's RM line eliminates O-rings from the design entirely — a real, vendor-stated reliability claim that removes one of the most common sealless-pump degradation points (O-ring swell/hardening under chemical attack) rather than just specifying a more resistant O-ring material.
Sealless doesn't mean maintenance-free if the design still leans on O-rings that harden or swell under attack — Richter's RM family removes that failure point structurally, which matters more in a mining acid-recycling loop than any single pressure or temperature spec on the datasheet.
Every claim on this page traces to real, vendor-published documentation on file with LibertyCES. Confirm current specifications with the manufacturer before final specification.
