Air Operated Diapgramph Pump
Air Operated Diapgramph Pump
Compact and High Water Discharge!
Safe Design with Intrinsically Explosion-proof Specification. An air-powered diaphragm pump that can transport highly flammable liquids at high pressure.
Fully self-suction type that can pump out fluid efficiently, with no pump-priming required. This series of diaphragm pumps are suitable for slurry without the risk of leakage due to seal friction.
Main Applications
Collection of Waste Liquid/Sludge/Supply of Paint To Roll Coater/Collection of Cutting Oil/Application of Adhesives/Application of Mold Release Agent/Mold Coating Material

1 The maximum supply air pressure for a type with a resin-made pump body will depend on the liquid temperature.
2 The water discharge is provided as a rough approximation only. The discharge will differ depending on factors such as the liquid to be transferred and the piping conditions.
3 Maximum flow rate is a value indicating the pump capacity. We recommend selecting a size that allows some leeway, taking into account the impact on the life span of the diaphragm.
