I'm currently doing a testing on hand pump from 2 different brand. Lets say Brand A and brand B.
Brand A hand pump is 20cc/cycle with maximum pressure 350 bar, Brand B hand pump is 25cc/cycle with maximum pressure 350bar as well.
1. brand A hand pump easily pump up to 92bar, but after i tried it for about 30 mins, its pressure only increase to 98bar. While brand B hand pump can be easily pump up to 100bar, and then take about 30mins to pump it up to 110bar. What do you think? Is it the quality of the hand pump or its have something to do with the displacement of the hand pump?

2. Is the displacement per cycle affected its performance?

Can anyone give me any opinion????

Definitely is the displacement.It similar to engine displacement.Just like a 2.5 litres engine will have more torque than a 2 litres engine.It is base on the how big the bore size of the cylinder and this apply to your hand pump too.
