NDP-H50/H500 series
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-H50 series has a nominal diameter of 2" (50 mm) and a maximum flow rate of approximately 460 L/min.
The maximum size solid is 8 mm or less.
■ Main Applications
Application of Mold Release and Coating Agents/Circulation and Spraying of Mold Release Agent, Pumping Out Factory Wastewater and Waste Oil/Supplying Oil, Coolant Fluid, Paint, Etc.
Features
■ For High Discharge Pressure and Low Speed Operation
Achieves the highest discharge pressure in the industry of up to 0.85 MPa and stable stroke even at low speed operation.
■ Expanded Operating Pressure Range
Allows for reduced load on the material thanks to the low-pressure operation.
■ Specifications with Reduced Drive Air Loss
Specifications achieving energy-saving effects and enhancing the push-in pressure of the material are used.
◆Mechanical Switch
| Achieves Low Pressure, Low Speed Operation, and Push-in High Pressure |
The actuation of the slide valve linked to the center rod connected to the left and right diaphragms enables the left and right stroke and reliable switching operation of the diaphragms. |

*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. It will differ depending on the usage conditions, etc.
*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.
