There is a huge necessity of stuffing box between impeller side and motor side.
The stuffing box is mainly required to prevent the leakage of the pump at that place as this is the main region from where maximum leakage takes place. That is why you need to put some conventional packing or mechanical seal inside (sometimes or outside) the stuffing box. Otherwise the product (say water) being pumped can contaminate the function of the motor by easily entering into this.
If you need any further details you can contact me.

is connected to the motor shaft indirectly.
