4 sector applications

Where LibertyCES specs Sealless Pump

Mining

Moderate evidence
Richter MNK/QMD/RM

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

Chemical Processing

Strong evidence
Finish Thompson UCR326 · DB Series

Chemical processing explicitly named sector.

Plating

Strong evidence
Finish Thompson VKC/MSVKC

Plating explicitly named sector for vertical sealless mag-drive pumps.

Food & Beverage

Moderate evidence
Finish Thompson AC Series

Food processing, breweries explicitly named sectors (mechanical-seal, not sealless technology, but closest category).

5 chemical compatibility records

Chemical compatibility

Acids

Moderate evidence
Phosphoric AcidNitric Acid
Materials: PFA · PTFE · ETFE · CFRP/PTFE (double can)
Richter MNK/RM · Finish Thompson UCR/UCP ANSI sealless

Richter's mag-drive line names phosphoric/nitric acid in its industries data; Finish Thompson UCR/UCP is ETFE/PP-lined for chemical processing generally.

Oxidizers/Disinfectants

Strong evidence
Sodium Hypochlorite (Hypo)Peracetic Acid (PAA)Bromine (Production)
Materials: PFA · PTFE · conductive PFA
Richter MNK/RM Series

Richter Industries page explicitly names Bromine Production, sodium hypochlorite, and PAA in F&B CIP context for its sealless mag-drive line.

Caustics/Bases

Moderate evidence
Caustic Soda (NaOH)
Materials: PFA · PTFE
Richter MNK/RM · Finish Thompson UC/UCR

Richter names caustic soda explicitly in its base-chemicals process list.

Salts/Brines

Light evidence
Brine (Chloralkali electrolysis)
Materials: PFA · EN-JS 1049
Richter MNK/RM

Chloralkali electrolysis (brine feedstock) explicitly named among Richter's process chemistries.

Solvents/Organics

Light evidence
MDITDI
Materials: PFA · PTFE
Richter MNK/RM

MDI/TDI (isocyanate organics) production explicitly named as a process chemistry for Richter's mag-drive pumps.
