NDP-E series (Solenoid- Controlled series)!!
The video shows how an NDP-E (i.e. a solenoid controlled pump) works!
This model has a high-frequency transmission proximity sensor in the pump.
The proximity sensor detects the stroke end of the diaphragm, and the pump driver that receives the sensor signal controls the center exhaust type 3-position 5-port solenoid valve to operate the pump.
Operation is reliable and low stroke motion is no problem.
Operation with an instrumented sequencer is also possible.
However, please note this type is not explosion-proof.
Please check it out!!
