Operation:

The T218 Pump-Out Cementing Sleeve is used for cementing liner strings in the well bore usually run above the T440 Casing Packer. The T218 Pump-Out Cementing Sleeve is run above the T440 Casing Packer, once the Casing Packer is set (tension or compression) the T218 is activated by gravitating a ball into the lower seat, applied pressure shifts lower seat and opens port holes for cementing. After the cementing operating is completed, pump the wiper plug into the upper seat and apply pressure to shift the closing sleeve over the port holes. Final pressure to shift the closing sleeve over the port holes. Final pressure of 2500 PSI will pump out all internal parts of the T218 Pump-Out Cementing Sleeve.
