Shutting the Fluid Discharge of an Air-Operated Reciprocating Pump

What will happen when the fluid discharge of an air-operated reciprocating pump is shut? This will cause the pump to OVERSTROKE.

Overstroke happens when the engine is switching in a normally-closed manner.

Explanation:

In pneumatic pumps, compressed air is utilized to generate a force that is used to channel fluids through the piping system. If the discharge line of the pneumatic pump is blocked the pump will stop and the fluid won't flow, the pump won't run and airflow will also stop. Pneumatic pumps have weak drivers. The compressed air which runs the pump is also at low pressure.
