Description
The GSP liner hanger was primarily designed for deviated and horizontal holes and for heavy liner. Its slips are recessed into a special profile at the rotating body. This ensures trouble-free installation and uniform load distribution in the setting section. In set and non-set states, the GSP liner hanger allows a very high bypass, ensuring a high flow rate with low pressure loss.
