Pumps differ in details like manufacturing tolerances (i.e. because of material properties), sealing material, pressure, flow, admission or no admission of oil vapor, service intervals, reliability, tolerance to dust, tolerance to chemicals, tolerance to liquids and vibration.
Because of all these variables, it's impossible or virtually impossible to create a vacuum on earth. Even the vacuum where the Space Station resides, is not a real vacuum: tiny particles exist everywhere within our visable universe.
The less air molecules resides in a chamber, the harder it is to remove the last ones. That's not linear.

No even if you had a perfect pump, molecules will enter via the walls of chamber there will always be some air left in the chamber, for the a similar reason a pump can't remove all the water from a swimming pool. there is always some water on the sides of the swimming pool and in the bottom.

The vacuum pump works with a motor. The gas interior the chamber occupies the area between the blades of the fan interior the motor. while the fan rotates with extreme velocity the air between the blades is pushed out area. The tension of air between the blades is rather decrease than the strain of air interior the chamber. as a result there's a non-give up flow of air from the chamber to out area as long because of the fact the strain of air interior the chamber is greater than the strain between the blades. as quickly as those 2 pressures grow to be equivalent, equilibrium is attained and there is not greater flow of air from the chamber to outdoors. assume we pour water from a bucket with a small cup and throw it out. while the point of water reaches the top of the cup, we won't be able to pour water from the bucket.

Depending on the type of pump you use, what you are left with will vary in the number of atoms per Cubic centimeter left. But you will never get it down to zero. (even deep space has a few atoms per Cubic met re!)

In real world you can not suck all the air
because you have leakage between the piston and cylinder in pump .It is one of the important specification of pump

it is impossible to create total vacuum in the Lab.
