The centrifugal pumps of the IN-VB 2 Type are similar as the manual show. Only the number of stages are the different coresponding to different flow rates.
In the case of a dry run or a similar damage, the manual from the manufactures home page is very helpful.

The manual also provide numbers for torque for bolted connenctions and more.
