The Downhole Filter-Flow Sand Separator is designed for oil wells with sand production. Through tangential liquid inlet, cyclone separation, flow filtration, and secondary sand settling, it separates sand and fine solid particles from produced fluid before the fluid enters the pump. It helps reduce pump wear, prevent blockage, improve pump service life, and meet sand-control requirements for different wells.

Formed by mold pressing, with no welding or rivets. The whole centralizer has a firm and reliable structure. Three-piece design

The Pumping Unit Polished Rod Hanger is used to connect the polished rod with the horsehead of the pumping unit. It helps keep the polished rod centered at the wellhead during operation and ensures smooth and stable rod movement. The structure eliminates complicated wire rope fixing procedures and improves installation efficiency and operational reliability.
