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.
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-5 series has a nominal diameter of 1/4" (8 mm) and a maximum flow rate of approximately 11 L/min.
*Slurry cannot be handled because it is a flat valve type.

- The silencer is built into the pump body. Rc 3/8 threaded holes are provided for connection to a hose that leads exhaust air to a duct, etc.
- 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. The discharge will differ depending on factors such as the liquid to be transferred and the piping conditions.
- 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.
- Slurry cannot be handled because it is a flat valve type.
