Air Operated Diapgramph Pump
Air Operated Diapgramph Pump
Compact and High Water Discharge!
Safe Design with Intrinsically Explosion-proof Specification. Has discharge capability equal to or better than the NDP-25. An air-powered diaphragm pump that can transport highly flammable liquids. The lineup includes aluminum models with 40A suction and 32A discharge ports.
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-32 series has a maximum flow rate of approximately 190 L/min. The maximum size solid is 3 mm or less.
Main Applications

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.
