Highest Discharge Pressure in the Industry!
Safe Design with Intrinsically Explosion-proof Specification. Mechanical air switching valve for low-speed operation and push-in high pressure is equipped. This is a diaphragm pump ideal for filter presses, circulation operations, and supply pumps for spraying. 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. The NDP-H80 series has a nominal diameter of 3" (80 mm) and a maximum flow rate of approximately 610 L/min. The maximum size solid is 10 mm or less.■ Main Applications

- The maximum supply air pressure for a type with a resin-made pump body will depend on the liquid temperature.
- The water discharge is provided as a rough approximation only. It will differ depending on the usage conditions, etc.
- 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.
