NDP-25-E series
Lightweight and Compact! Simple Structure and Easy Maintenance
This model has a built-in high-frequency transmitting proximity sensor.
This diaphragm pump operates by detecting a sensor and controlling the switching of a solenoid valve.
Fully self-suction type that can pump out fluid efficiently, with no pump-priming required.
The NDP-25-E series has a nominal diameter of 1" (25 mm) and a maximum flow rate of approximately 105 L/min.
The maximum size solid is 3 mm or less.
*The NDP-E series Is Not Explosion-proof. This Series Is Built-to-order, So Be Sure to Confirm the Delivery Date.
■ Main Applications
Transfer of Inks and Pigments/Circulation and Spraying of Mold Release Agent, Pumping Out Factory Wastewater and Waste Oil/Supply of Paint to Roll Coater/Transfer of Clay and Glazes/Supplying Oil, Coolant Fluid, Paint, Etc.
Features
■ Sensor Control Model with Built-in Proximity Sensor that Transmits High Frequencies
The sensor built into the pump detects the stroke end, and the pump controller switches the solenoid valve to operate the pump.
◆ Sensor Control “Proximity Sensor”
| Sensor Control = Stable Reciprocating Motion |
|
A proximity sensor detects the stroke end of the diaphragm, and the pump controller receiving the sensor signal controls the switching of the center exhaust type 3-position 5-port solenoid valve. |
|
Optional Counter Connection Enables Stroke Management |
|
By counting the number of times the center rod has moved, it is possible to determine when parts need to be replaced. |

*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.
