Surface Treatment Pumps (Plating, Anodizing, Etch, Wash & Rinse)
Surface finishing runs on chemical compatibility, leak-free containment, and stable flow. We apply mag-drive sealless for corrosives/solvents, vertical immersion for open tanks, inline/end-suction for rinse/utility, and drum/IBC systems for ergonomic loading. Precise ppm is delivered by digital/peristaltic metering with validation hardware. Brands: Finish Thompson, Iwaki, LMI, Neptune, Emec, Walchem, Flux, Grundfos, Goulds, Griswold, Wilden, Yamada, ARO, J.L. Wingert, Gorman-Rupp.
Best-Fit Pumps for Surface Treatment
| Service | Best Pump Type | Recommended Brands | Why It’s Best |
|---|---|---|---|
| Acid/alkali/oxidizer recirculation | Mag-drive sealless centrifugal (PP/PVDF/ETFE/SS) | Finish Thompson DB/UC; Iwaki MX/MD | No seal leak path; broad chemistry range and low maintenance |
| Open tank transfer / filter loops | Vertical immersion (sealless) | Finish Thompson; Iwaki | Dry-run tolerant bearings; keeps motor out of fumes and condensate |
| Rinse cascades / utility circulation | Inline / end-suction centrifugal | Grundfos; Goulds; Griswold | Efficient, quiet pressure control across baths and rinse stages |
| Brightener/leveler/accelerator dosing | Digital diaphragm / Peristaltic metering | LMI PD/TD & KML/KBL; Neptune; Emec; Walchem (control) | High turndown ppm accuracy with validation hardware |
| Drum/IBC chemical loading | Drum/IBC pump + injection hardware | Flux; J.L. Wingert | Ergonomic transfer; calibrated columns, quills, and sampling |
| Portable chemical transfer / cleanup | AODD (chem-compatible kits) | Wilden; Yamada; ARO | Self-priming, run-dry tolerant; easy to flush and maintain |
| Sumps & containment | Self-priming or submersible utility | Gorman-Rupp; BJM | Quick clean-out above grade or compact pit service |
Compliance: We align materials to SDS and integrate pH/ORP control, interlocks, and containment to meet EHS and emissions goals.

How We Engineer Surface Treatment
- Containment first: sealless designs on corrosives/solvents whenever feasible.
- Right wetted parts: PP, PVDF, ETFE, or alloys chosen to the SDS and temperature.
- Validated dosing: back-pressure, anti-siphon, columns, and quills tied to control I/O.
- Uptime: easy-service self-primers or guide-rail subs for sumps and spill control.
- Integration: pH/ORP loops, level interlocks, and ventilation tie-ins where required.

Surface Treatment FAQs
Mag-drive or vertical immersion—what goes where?
Use mag-drive for closed containment and transfer; pick vertical immersion for open tanks to keep motors out of fumes and allow dry-run tolerant operation at the surface.
How do you keep additive dosing consistent at low ppm?
Digital or peristaltic metering with back-pressure, anti-siphon checks, calibration columns, and injection quills—integrated to your pH/ORP control loop.
What materials survive mixed chemistries?
PP and PVDF cover many acids/alkalis; ETFE or alloys extend range for oxidizers and solvents. We match every wetted part to your SDS and temperature.
