Please suggest me a vfd for control a 20kw pump via ethernet?

do vfd shall be 20kw sufficient or slightly higher 30kw?

Hello,

a special drive for pumps with a lot of pumping and ventilation features (as deragging, pipe filling mode, ...) is the SINAMICS G120X. It has a PROFINET interface so you can simply communicate to your PLC by using ready-to-use SIMATIC function blocks like SINA_SPEED FB for example.

To find the right order number there are several options, such as using the SINAMICS Selector App or ask your local sales rep...

An element of the control strategy has been discussed here, however it is not clear what devices are required for the ‘working’ end of the system.

Is this one 20kW pump working in isolation?

Also detail regarding:

Product, Head, flow, pressure, and range of control?

Pump type, centrifugal, positive displacement, peristaltic, submersible etc?

This detail will enable the rating to be confirmed.
