The pump and compressor tube heads are units that connect the
upper and lower flanges with two annular side outlets. Also known
as elevator column suspension screws, the upper flange is
equipped with locking screws to fix the elevator column
suspension.
The NKT head is installed at the top of the siege column head and
consists of two parts: the elevator shell and the hanger. It is
used to lift the elevator column and seal the annular space
between the pipeline and the elevator column.
Our NKT head has a standard structure and is equipped with a
suspension device for elevator columns on its conical adapter.
This device can be equipped with a threaded check valve as
required.
