The sodium potassium pump requires ATP - i.e. it is involved in active transport, not facilitated transport.
Secondary active transport aka facilitated diffusion [depending on your teacher].

Active transport
sodium-potassium pump.
A sodium potassium pump is different from diffusion cos, it requires energy (ATP), and therefore is a active transport. Rather then diffusion which is the passive transport of solutions across cell membranes without using energy, and is determined by the concentration gradient.
In a sodium-potassium pump a carrier protein uses ATP in Active transport. The sodium ions are transported out of the cells and the potassium ions are transported into the cell.
When number of sodium-potassium pump decreased, transport of Na takes little more time. Less number of sodium-potassium more time for transport

Potassium is distributed by passive diffusion.
