Paints, Dyes & Coatings Pumps (Pigments, Solvents, Resins)
High viscosity, abrasive pigments, and flammable solvents demand the right hydraulics and materials. We deploy gear and progressive-cavity for viscous bases and resins, AODD for rugged transfer and pigment slurries, mag-drive for solvent handling, and peristaltic for shear-sensitive or off-gassing fluids. Brands: Roper, Blackmer, Netzsch, Wilden, Yamada, ARO, Finish Thompson, Iwaki, LMI, Neptune, Emec, Walchem, Flux, Grundfos, Goulds, Griswold, Gorman-Rupp, BJM, Graco.
Best-Fit Pumps for Paints & Dyes
| Service | Best Pump Type | Recommended Brands | Why It’s Best |
|---|---|---|---|
| High-viscosity base, resin, latex | External gear (relief) / Progressive-cavity (VFD) | Roper, Blackmer; Netzsch | Stable PD flow across viscosity; PC gives low-shear conveyance |
| Pigment slurries / abrasive blends | AODD (bolted, abrasion kits) | Wilden; Yamada; ARO | Run-dry/dead-head; handles solids and batch variability |
| Solvent transfer (toluene, MEK, xylene) | Mag-drive sealless centrifugal | Finish Thompson DB/UC; Iwaki MX/MD | Leak-free containment for VOCs; broad compatibility |
| Tinting & additive dosing | Peristaltic / Digital diaphragm | LMI KML/KBL; LMI PD/TD; Neptune; Emec; Walchem | Accurate ppm; hose option for off-gassing or crystalline fluids |
| Drum/IBC unloading (solvent or latex) | Drum/IBC pump | Flux | Portable, ergonomic; tube sets for solvents, water-based, or oils |
| Tank farm transfer / loadout | Self-priming / End-suction centrifugal | Gorman-Rupp (self-priming); Grundfos/Goulds/Griswold | Fast priming/clean-out; efficient bulk transfer where fluids are thin |
| Sumps / spills / cleanup | Submersible (abrasion-tolerant) | BJM | Immersed duty with abrasion options for fines |
Note: We confirm viscosity vs. temperature, solids %, explosion-protection requirements, conductivity/grounding, and elastomers against your SDS.

How We Engineer Coatings Duty
- Viscosity & shear: PD for thick bases; PC/peristaltic for shear-sensitive media.
- Abrasives: hardened wear parts, slower tip speeds, and generous NPSH margin.
- Solvent safety: sealless transfer, bonding/grounding, and vapor management.
- Controls: VFDs and closed-loop metering for precise batch/continuous flow.
- Serviceability: clean-out ports, quick-change hoses/stators, and standardized kits.

Paints & Dyes Pump FAQs
When should I choose gear vs. progressive-cavity?
Use gear for steady PD transfer of medium-to-high viscosity resins and oils; choose progressive-cavity for very high viscosity or when low shear is critical.
Are AODD pumps OK with abrasive pigments?
Yes—use bolted housings with abrasion-resistant wetted parts and keep speeds modest. AODD handles solids and batch upsets well.
Why mag-drive for solvents?
Sealless designs eliminate a mechanical seal leak path and improve containment for VOCs—key for compliance and safety in solvent handling.
