What LibertyCES's vendor documentation shows

Mag-drive pumps are inherently sealless; same Mining & Ore sector evidence.

Products cited in this application

Richter MNK/QMD/RM

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 tierrichter-ct-magnetic-drive-pumps.md
RM sealing detailRM does not require O-rings — a distinct sealing-philosophy differentiator from MNK's PFA/PTFE/PFA-conductive lining optionsrichter-ct-magnetic-drive-pumps.md
Shared housing/magnet materialsEN-JS 1049 / ASTM A 395 ductile iron housing; magnetic coupling uses SmCo and NdFeB rare-earth permanent magnetsrichter-ct-magnetic-drive-pumps.md
CertificationsMNK/MPB/RM certified to 2006/42/EC (Machinery Directive) and 2014/34/EU (ATEX)richter-ct-magnetic-drive-pumps.md
Install / Failure Note

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.
