seal, just rely on differential pressure seal in well.

       Feature

• No anchor structure, and can be used in horizontal, shallow and deviated 

wells, without restricted for.

• The cup can be installed on two side (maintain the pressure from two 

directions), also can be the same side (up or down) so that it can be assembled and disassembled easily.

or pressure. It could set and seal the casing and tubing annulus just with the 

string. Save time and expenses.
