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

  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.
