This page lists the motor-diaphragm series. HND and ND1000 are in this series even when the model code looks like another drive. Digital cards are on the digital page.
Each card prints its own maximum flow and maximum back pressure. Those two figures are opposite ends. Some motor cards list 380 V among the supply options. That is not a separate product line.
