Air Operated Diapgramph Pump
Air Operated Diapgramph Pump
Lightweight and Compact!
Safe Design with Intrinsically Explosion-proof Specification. 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.
There are no sliding parts in wetted parts, eliminating the risk of liquid leakage due to seal friction.
The NDP-15 series has a nominal diameter of 1/2" (15 mm) and a maximum flow rate of approximately 50 L/min.
The maximum size solid is 1 mm or less.
Main Applications
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 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.
2 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.
