White Knight PSD Series air-operated double-diaphragm (AODD) pumps feature PTFE or UHMW (PE), corrosion-resistant fluid paths, which make the pumps ideal for corrosive or toxic liquids such as fuels, glues, paints, resins, inks, or wastewater, as well as more viscous fluids and slurry.
The pumps are available in 1/4, 3/8, 1/2, 1, or 1-1/2 in models. They feature high-quality machined designs, unique sealing surfaces, and tight bolt configurations to ensure consistent, reliable performance and superior product containment. They have no exposed metals and may be configured in various materials to meet most abrasion, temperature, and chemical compatibility requirements. They are dead-head capable and achieve high flow rates while minimizing air consumption and operational noise. The pumps have non-lubricated, self-priming, icing-resistant air systems.
PSD Series pumps are easy to install, operate, and service. They can be serviced in the field to minimize repair costs, downtime and production loss. They require only minimal parts to rebuild and can be rebuilt in situations that would require other AODD pumps be replaced, which increases pump life and decreases total costs of ownership.
