Transfer Requirements in Paint and Coating Applications
In the paint and coating industry, fluid transfer is a critical part of the overall process, covering raw material handling, production, formulation, and packaging. Compared with general industrial liquids, paints and coatings often feature wide viscosity ranges and complex compositions, which place higher demands on pumping equipment.
Some coatings are highly sensitive to temperature changes, while others contain pigments or fillers that must remain evenly dispersed. An unsuitable pump selection may not only reduce efficiency but also negatively affect coating performance and final appearance.
Challenges of Handling Complex Media
Paints and coatings are rarely uniform fluids. Pigments and fillers must remain stable within the formulation. Excessive shear during pumping can cause viscosity changes, separation, or settling.
AODD pumps operate using a reciprocating diaphragm motion, providing relatively low-shear transfer compared with many rotary pump types. This makes them well suited for preserving formulation stability during transfer.
In addition, some coatings tend to settle during downtime, requiring pumps that can restart reliably after short interruptions.
Safety as a Key Selection Factor
Safety considerations play a major role in coating applications. Many solvent-based paints are flammable or volatile, requiring strict risk control during handling.
Because AODD pumps are powered by compressed air rather than electricity, they inherently reduce the risk of sparks or overheating. This structural advantage makes them a common choice for hazardous or explosion-risk environments.
Flexibility for Variable Operating Conditions
Paint production and application processes often involve frequent start-stop operation and product changeovers. AODD pumps offer strong self-priming capability and can tolerate short periods of dry running, allowing them to adapt to these changing conditions.
A Proven and Practical Industry Solution
Rather than being selected for complexity, AODD pumps are valued for their balanced performance in safety, adaptability, and reliability. These characteristics explain why they remain widely used throughout the paint and coating industry.
