Air Operated Diapgramph Pump
Air Operated Diapgramph Pump
Simple Structure for Easy Maintenance!
An air-powered diaphragm pump that can transport highly flammable liquids.Fully self-suction type that can pump out fluid efficiently, with no pump-priming required. The safety structure does not require explosion-proof measures, so it can be used anywhere.
By simply opening and closing the valve, cutting off the flow at the end point is possible or water discharge can be controlled easily and safety.The NDP-80 series has a nominal diameter of 3" (80 mm) and a maximum flow rate of approximately 840 L/min. The maximum size solid is 10 mm or less.
Main Applications
Cleaning of Crude Oil and Raw Material Tanks/Transfer of Slurry/Circulation of Mold Release Agent/Pumping Out Sprays, Factory Wastewater, and Waste Oil/Transfer of Flammable Liquids in Explosion-proof Areas/Supply of Paint to Roll Coater/Drainage from Power Plants/Waste Liquid Collection during Piping and Tank Cleaning/Fuel Transfer in Explosion-proof Area/Transfer of Clay and Glazes/Transfer of Food Ingredients and Additives/Transfer of Alcohol, Disinfectants and Solvents/Supplying Oil, Coolant Fluid, Paint, Etc./Transfer of Anhydrous Powder

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.
