Plating Pumps (Acid, Alkaline, Cyanide, Chromic Lines)
Plating lines punish equipment with oxidizers, acids/alkalis, and fines. We spec mag-drive sealless (PP/PVDF/ETFE) or vertical sealless for tanks, digital & peristaltic metering for brighteners/pH, AODD for sludge and progressive-cavity where viscosity or solids demand steady, low-shear flow. Brands: Finish Thompson, Iwaki, LMI, Neptune, Emec, Walchem, Wilden, Yamada, ARO, Netzsch, Flux, J.L. Wingert, Grundfos, Goulds, Griswold, BJM, Gorman-Rupp.
Best-Fit Pumps for Plating
| Service | Best Pump Type | Recommended Brands | Why It’s Best |
|---|---|---|---|
| Bath recirculation & filter carts (acid/alkali/chromic) | Mag-drive sealless / Vertical sealless (PP/PVDF/ETFE) | Finish Thompson DB/UC/SP; Iwaki MX/MD | No seal leak path; plastics resist oxidizers and plating chemistries |
| Brighteners, wetters, pH adjust | Digital diaphragm / Peristaltic dosing | LMI PD/TD; LMI KML/KBL; Neptune; Emec; Walchem (control) | Accurate ppm; peristaltic handles off-gassing & crystallizing additives |
| Fume scrubber liquor / pickling transfer | Mag-drive sealless centrifugal | Finish Thompson; Iwaki | Containment for corrosives; simple maintenance |
| Sludge/precipitate transfer (clarifiers) | AODD (bolted) / Progressive-cavity (VFD) | Wilden, Yamada, ARO; Netzsch | Rugged solids handling or smooth, low-shear cake feed |
| Rinse water loops / backwash | Inline / end-suction centrifugal | Grundfos TPE; Grundfos NB/NK; Griswold; Goulds | Quiet, efficient circulation with back-pull-out service |
| Drum/IBC chemical make-up | Drum/IBC pump + validation hardware | Flux; J.L. Wingert (columns, quills) | Ergonomic unloading; calibrated injection for compliance |
| Sumps/spill containment | Submersible / Self-priming | BJM; Gorman-Rupp | Immersed reliability or above-grade serviceability |
Note: We match elastomers and plastics to chromic acid, nitric, hydrochloric, cyanide and alkaline cleaners. Grounding/bonding guidance available.

How We Engineer Plating Duty
- Containment: sealless for oxidizers/solvents; venting and secondary containment where needed.
- Filtration: proper turnover and head for filter media loading.
- Dosing accuracy: back-pressure, anti-siphon, columns/quills for validation.
- Materials: PP/PVDF/ETFE plastics, ceramic/SiC bearings, and compatible elastomers.
- Serviceability: quick-change hoses/stators, back-pull-out frames, isolation and drains.

Plating Pump FAQs
PP or PVDF—what should I select for chromic acid?
PVDF offers superior resistance to strong oxidizers like chromic acid; PP can be fine for many acids/alkalis. We confirm against your SDS and temperature.
Peristaltic vs. diaphragm for additives and pH?
Digital diaphragm is precise at pressure; peristaltic excels with off-gassing or crystallizing chemistries and hose-only wetted parts.
Can you furnish filter carts and validation hardware?
Yes—pumps, filter housings, calibration columns, injection quills and controls for a complete, spec-ready package.
