AODD Pumps for Paints and Coatings

Built for Abrasion, Solvents and Color-Critical Production

Unlike many industries and AODD pump markets, coating lines must move fluids that actively attack pump components such as gritty solids that erode internals, solvent blends that stress elastomers and high viscosity bases that challenge flow consistency. Pumps used need to be able to handle:

• Abrasive pigments such as titanium dioxide and iron oxides.
• Solvent-borne formulations that demand chemical-resistant materials.
• Water-borne coatings that require fast cleanup and low residual carryover.
• Resins, binders and epoxies with variable viscosity and shear sensitivity.
• Additives and modifiers that may clog restrictive flow paths.

This combination makes the paints and coatings sector highly abrasive, highly chemical and highly cleanliness sensitive.

Reducing Wear Without Compromising Batch Quality

Wear and color contamination are major concerns in coating plants. When diaphragms wear prematurely, pigment slurries lose consistency, and a single leak can ruin a batch’s opacity or tint accuracy.

AODD pumps by Wilden® and All-Flo™ are designed for this environment and use materials that resist long-term abrasion.

For example, Dunn-Edwards Paints, a paints and coatings manufacturer, documented significant reduction to TiO₂-related diaphragm failures after switching to Wilden® Chem-Fuse™ technology. This was due to Chem-Fuse™ diaphragms being engineered to gold up against acids, caustics and other aggressive fluids, such as latex. These sane durability benefits apply directly to manufacturers handling abrasive pigments or running high-volume production, too.

Solvent Handling That Doesn't Slow You Down

Solvent-borne paints place heavy demand on pump internals and air systems. Selecting the proper pump configuration allows teams to:

• Handle aggressive solvents without damaging diaphragms by running solvent-borne coatings confidently and avoiding unexpected pump failures.
• Maintain steady, reliable flow during batch mixing, to ensure that there’s even movement of pigments and resins leading to more consistent, accurate batches.
• Switch between resin and solvent formulations with minimal delay for faster transitions that keep production timelines on track.
• Clean and flush pumps quickly during product changeovers for rapid removal of residual material reducing contamination risk.
• Adapt pumps to different chemistries with quick diaphragm swaps and adjustments that improve flexibility for processes running multiple lines.

Configured for Real Coatings Production

Coating teams need pumps that can reliably handle solvents, resins and abrasive pigments that make these products. That’s why recommended configurations emphasize bolted aluminum construction paired with abrasion-resistant diaphragms capable of withstanding repeated exposure to TiO₂ and high-solids formulations. These materials not only resist wear but also help maintain consistent flow needed for tint accuracy and batch uniformity.

Using standardized rebuild kits and genuine parts can simplify maintenance for teams that balance multiple product lines with frequent changeovers. Together, these design choices reduce downtime, extend pump life and support the demanding production schedules common in modern paint and coatings facilities.
