Number of Moving Stages*

Total Stroke (in)*

Pressure (PSI)*

Flow (GPM)*

Outside Diameter (OD) of Moving Stages (in)

Be sure that each stage is smaller than the previous stage. Stage 1 is the largest stage.

Stage 1 - OD of Moving (in) (Largest Stage)*

Stage 2 - OD of Moving (in)*

Stage 3 - OD of Moving (in)*

Stage 4 - OD of Moving (in)*

Stage 5 - OD of Moving (in)*

Inside Diameter (ID) of Previous Stages (in)

Be sure that each stage is smaller than the previous stage. Main barrel is the largest ID.

Main Barrel - ID (in)*

This value should be greater than the Stage 1 OD from above.

Stage 1 - ID of Previous (in)*

This value should be greater than the Stage 2 OD from above.

Stage 2 - ID of Previous (in)*

This value should be greater than the Stage 3 OD from above.

Stage 3 - ID of Previous (in)*

This value should be greater than the Stage 4 OD from above.

Stage 4 - ID of Previous (in)*

This value should be greater than the Stage 5 OD from above.
