The actual volume of the cylinder that is swept by the piston per minute is piston displacement. It can be calculated from:
Single acting cylinder (head end displacement)
Single acting cylinder (crank end displacement)
Double acting cylinder (sum of head end and crank end displacement)
Throughput can be changed directly by changing the piston displacement. This can be accomplished by changing the speed, by removing or deactivating suction valves, or by converting a double acting cylinder to single acting.
In addition, piston displacement and thus throughput can be changed by changing cylinder liners, installing sleeves, or boring the cylinder.
