How does an Air Operated Pump work?

An Air operated Pump has 2 main parts – A double-acting air motor and a double-acting liquid pump. The double-acting air motor drives a double-acting liquid pump. The liquid is sucked into the pump tube through the bottom valve when the piston is on the upward stroke and is discharged in both up and down strokes.

What does 3:1 ratio mean?

The amount of air coming into the pump (input pressure) is one-third the amount of liquid leaving the pump (output pressure). For example, if the pump has 50 PSI of air going in then, there will be 150 PSI of pressure pushing the fluid out.
