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.
A pump with an intrinsically explosion-proof specification, for use on lines at chemicals plants, etc. 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. The NDP-25 series has a nominal diameter of 1" (25 mm) and a maximum flow rate of approximately 160 L/min. The maximum size solid is 3 mm or less.
Main Applications
Collection of Waste Liquid/Sludge/Transfer of Factory Wastewater/Alcohol/Transfer of Ethanol/Transfer of Lubricant and Hydraulic Oil/Supply of Paint to Roll Coater/Collection of Rainwater/Wastewater Treatment during Regular Repair/Preparation of Raw Materials (Various solvents)/Collection of Cutting Oil/Removal of Fuel (Gasoline and Diesel Oil)/Transfer of Slurry/Recovery of Floating Oil

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.
