概述
The Polychem non-metallic telescoping head shaft was invented and installed as part of the first 100% non-metallic system in 1984. At that time, the industry was just beginning to test plastic as a lighter, corrosion-resistant alternative to steel. Today, Polychem non-metallic head shafts have become the water treatment industry’s gold standard.
The head shaft’s unique assembly does not require crane installation and is virtually maintenance free. Two fiberglass end tubes with internal bearings and keyways overlap a center tube and are joined together with torque interlocks and set collars to form one robust, easy-to-lift shaft. Since its introduction, the Polychem telescoping head shaft design has been utilized in over 12,000 systems worldwide.
