NDP-P50 series (Maximum corrosion resistance)
Maximum Corrosion Resistance Pump!
Safe Design with Intrinsically Explosion-proof Specification. Highly corrosion-resistant polypropylene (PP-GF) is used for the center body.
A diaphragm pump that can be used to transport chemicals and a variety of conveying liquids.
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-P50 series has a nominal diameter of 2" (50 mm) and a maximum flow rate of approximately 630 L/min.
The maximum size solid is 8 mm or less.
■ Main Applications
Supply of Chemicals, Pure Water, and Waste Liquids/Transfer of Flammable Liquids in Explosion-proof Areas/Transfer of Food Ingredients and Additives/Supply of Pipe Cleaning Solution/Collection of Waste Oil and Wastewater/Transfer of Alcohol, Disinfectants and Solvents
Features
■ Highly Corrosion-resistant Polypropylene (PP-GF) is Used for the Center Body.
The product is resistant to corrosion and rust, making it suitable for transferring chemicals and a variety of conveying liquids.
■ Yamada’s Proprietary Design Air Switch Valve “C-Spool”
The air switch valve in the center section of the diaphragm pump is completely oil-free, so it does not require regular lubrication.
The operation assist using a C-spring suppresses stoppages during operation, and achieves stable operation.
◆ Air Switch Valve “C-Spool”
| The C-spring Prevents Stoppages during Operation Achieves stable operation. |
Equipped with a Reset Button Downtime due to pump stoppages in the case of wear of the air switch valve is kept to a minimum. |
 |
 |
| Completely Oil-free Both the air switch valve and the pilot valve that activates the air switch valve at the stroke limit are designed to be oil-free. Does not require regular lubrication. |
Simple Replacement No need to disassemble the pump when replacing it. |

*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.
