I would have a curiosity, I saw in some catalogs of oil pumps that is indicated the moment of inertia of the same.
what is this data used for?
Thank you very much

for determining the point torque or in the regimen adjustment conditions

So for our type of pumps that are started and work at constant rotation regime is practically an influential data, or is it wrong?

I would say yes. Sure that if you have pumps with great inertia and to start them to regimen it takes 60 seconds it is good to understand that if they were started directly they would take great hits and above all they would suck a lot of current. for this, however, an evaluation of inertia at the start would not be bad.
when you control a pump, you have the inertia of the engine rotor and that of the pump. star screws with ramp and then over the first 5/8seconds you go to the triangle to stay with the load until you turn off. alternatives are the soft start or normal programmable inverter.
who designs oleodynamic plants is good that a conticino does it, especially if it has to provide the electrical part.

we design/produce only pumps, so is it a useful value to indicate in the catalog?

If you are a manufacturer and manufacturer of pumps, I would say that it is as good as given. then who uses them takes into account or not. normal application, formation from cellar = not needed. otherwise yes
