Pump Station Modelling
Infoworks ICM pump station modelling principle is very basic, adding a pump between two nodes is highly hypothetical. There is no way to add pump station head losses.
I would like to suggest incorporating pump station modelling (for Rotodynamic pumps) with pump curve and system curve theory. Then the model results would be much more realistic.
There must be a tool to incorporate all the accessories in pump stations, between two nodes. Like pump station type, drywall wet well. And Parameters to calculate Pump suction and discharge losses, like all fittings, non-return valves, discharge valves, flow meters etc. This would be helpful for model calibration purposes.

If you simulate the pressure pipeline leading from the pump station, doesn't that give you the ability to approximate the system curve? If you already have the system curve and you want to replicate that, you may be able to use the link type "user control" and enter the head-discharge system curve there.
