To prevent clogging, sprayers need correct filtration and stable flow control without over-shearing the emulsion. Key features include properly sized strainers ahead of the pump and spray bar, low-shear pump selection, smooth-bore hoses with minimal sharp elbows, and recirculation that keeps material moving during pauses. Pressure regulation should be steady, not pulsing, to avoid nozzle flutter and streaks. Quick-access cleanouts, quick-change nozzles, and purge or flush capability reduce downtime. Temperature management also matters because viscosity spikes can trigger plugging.
