Solvent Transfer & Dosing (Aromatics, Ketones, Alcohols & Blends)
Solvents demand sealed containment, static control, and materials compatibility. We lean on mag-drive sealless centrifugal for closed-loop transfer, AODD with conductive kits for portable duty, and external gear for viscous clean solvents—plus drum/IBC systems and digital/peristaltic metering where precise ppm matters. Brands: Finish Thompson, Iwaki, Wilden, Yamada, ARO, Roper, Blackmer, Flux, LMI, Neptune, Emec, Walchem, J.L. Wingert, Grundfos, Goulds, Griswold, Gorman-Rupp, Graco, Iwaki, Finish Thompson.
Best-Fit Pumps for Solvents
| Service | Best Pump Type | Recommended Brands | Why It’s Best |
|---|---|---|---|
| Closed-loop solvent transfer / recirculation | Mag-drive sealless centrifugal (ETFE/PVDF/SS) | Finish Thompson DB/UC; Iwaki MX/MD | Eliminates mechanical seal leak path; broad solvent compatibility |
| Portable unloading, drum to day tank | AODD (conductive PTFE/EPDM; ATEX-style kits) | Wilden; Yamada; ARO | Self-priming, run-dry tolerant; conductive paths for static dissipation |
| Viscous clean solvents / blends | External gear pump (mechanical seal or mag-drive) | Roper; Blackmer | Pulsation-free, accurate flow for coatings and solvent-borne resins |
| Precise ppm solvent additives | Digital diaphragm or Peristaltic metering | LMI PD/TD & KML/KBL; Neptune; Emec; Walchem | High turndown with validation hardware; hose selections for compatibility |
| Drum/IBC loading & decant | Drum/IBC pump + injection hardware | Flux; J.L. Wingert | Ergonomic transfers; quills, columns, and grounding kits available |
| Tank farm truck offload (above-grade O&M) | Self-priming centrifugal | Gorman-Rupp | Fast prime, inspection cover clean-out; simple suction piping |
| Utility distribution (non-flammable solvents) | Inline / end-suction centrifugal | Grundfos; Goulds; Griswold | Efficient, quiet, serviceable for plant utilities and wash loops |
Safety notes: We specify bonding/grounding, conductive hoses/diaphragms, anti-static kits, and appropriate motor enclosures for hazardous areas.

How We Engineer Solvent Duty
- Containment first: mag-drive where feasible; seal plans when not.
- Static control: bonding/grounding, conductive kits, and anti-static paths.
- Right elastomers: PTFE, FFKM, EPDM, or FKM based on solvent family.
- Dosing validation: back-pressure, anti-siphon, columns, and quills.
- Serviceability: self-primers and modular wear parts to cut downtime.

Solvent Pump FAQs
When is mag-drive a must for solvents?
For toxic/flammable solvents or where emissions and seal wear are concerns, mag-drive eliminates the primary leak path and simplifies maintenance.
Do I need conductive AODD hardware?
Yes—use conductive diaphragms/valves, bonding/grounding, and anti-static kits to dissipate charge during solvent transfer.
Can peristaltic pumps handle solvents?
They can—select compatible hoses (e.g., FKM, EPDM, specialty chem hose). We match hose to solvent family, temperature, and duty cycle.
