White Knight High-Purity Pneumatic Bellows Pumps

Bellows Pumps

White Knight pneumatic bellows pumps feature PTFE/PFA flow paths. These reliable, leak-free pumps offer high flow rates, steady pressures and stable temperatures. They do not contain metals, elastomer O-rings, or electric motors. They are dead-head capable, and provide suction lift.

Diaphragm Pumps

White Knight pneumatic diaphragm (AODD) pumps feature PTFE or UHMW (PE) corrosion-resistant fluid paths. They are ideal for corrosive or toxic liquids such as acids, fuels, glues, paints, resins, inks, or slurry. PSB Series pumps are direct retrofit replacements for obsolete chemical delivery pumps.
