Description: rotor critical speed calculated considering the additional support and damping produced by the action of the pumped liquid within internal running clearances at the operating conditions and allowing for stiffness and damping within the bearings; Name: wet crit. Speed
Description: Rotor resonant frequency calculated considering the additional support and damping produced by the action of the pumped fluid within rotor  ; Name: Wet critical speed
Description: Motion direction (rotating direction) in the case of rotation. NOTE: The rotational direction takes place in view of the targeted end. Anti-clockwise shaft rotation (left L) is described as positive and clockwise (right R ) as negative. Rotational direction-independence is described with (S); Name: Rotational direction of the drive
