X.3454C We have tried an air pump with the pressing sweated at the top of the piston in order to increase the pressure from 2 lbs. to 3 lbs. We find that this is quite satisfactory. The maximum pressure depends on the leakage so that we must not expect to find all pumps will be exactly the same. EH. | ||
