Centrifugal pumps, motor with base good installation or without base good installation?

If it is a small pump, the motor and the pump as a whole base is better to install, because there is less to find equal a lot of trouble

If it is the power of more than 200KW of large pumps, or not with the base of the good, because the motor's vibration and the pump's vibration is quite large, easy to the stability of the equipment
