It is used as a tubing plugging device against which pressure is being applied in order to set Hydraulic Set Packers.

This is made up with the tail pipe below the Packer to be set.

With the ball seating down, it acts as a reverse check valve preventing flow down the string, while allowing the string to fill from below.

Without dropping a ball to seat, the tubing can be pressured up.

Once the Packer is set, tubing pressure is increased to values shown in the chart below to shear the screws holding the ball seat.

The ball seat and the ball with spring etc. are blown out of the sub to the bottom of the well.

Tubing below the plug should have sufficient ID clearance to permit passage of the ball, ball seat, spring etc.

To set a packer number of screws installed in the pump out plug must be compatible with the concerned/rated precise requirement.
