Introduction HYDROPOWER: Solutions that increase reliability and reduce costs – we improve performance in the hydropower industry

Chesterton is a global manufacturer of industrial fluid sealing systems, industrial coatings, lubricants, and maintenance specialties. Working with hydropower plants around the world, we have gained knowledge and expertise that continue to help us develop unique solutions to address the specific challenges faced by the hydropower industry, including fluid containment, corrosion and wear control, and critical plant assets management.

Chesterton’s unique portfolio of solutions and experience helps plants drive significant improvements in equipment availability and reliability.

Split Mechanical Seals

Chesterton® split mechanical seals for turbine main shafts are designed to seal without external leakage under suitable operations conditions and significantly reduce water filtration dependency. This innovative technology simplifies installation, improves reliability, and helps to extend performance capabilities.

Advanced Polymer Seal Technology

Chesterton’s innovative split, interlock, polymer sealing technology was designed for use in blade pitch control systems, found in Kaplan turbine runners, to improve reliability and minimize environmental concerns. The bi-directional seal design allows for precise positioning of blades while sealing the hydraulic fluid in and river water out.

Chesterton sealing experts have developed tailored sealing solutions, for wicket and gate cylinders, that provide long-term reliability. Our abrasion-resistant polymer materials with robust designs that accommodate these slow, rotary, oscillating equipment conditions are ideal for use in cold water service.

Rotary Live Load

Pump packing is ideal for the controlled leakage required for certain applications. ​Chesterton offers extensive application ​expertise in pump packing solutions for rotating equipment—including design, selection, installation, testing, and more. Our innovative packing solutions reduce power requirements for the pump and result in less leakage—lowering the total life cycle costs of the pumping system.

Chesterton’s rotary live load system is a technology that extends the time between packing adjustments by adding energy and preload to the gland-bolding systems. This technology consists of springs, washers, and guides that maintain sufficient gland load on the packing set over designed travel.

Chesterton® Industrial Coatings provide efficiency and protection

Our industrial coatings – ARC and Ceramic Polymer coating lines – offer effective solutions for protecting and rebuilding plant metal and concrete infrastructure and equipment that is subjected to corrosion, wear, and environmental damage. Our low-VOC, 100% solids, protective coatings are engineered to offer long-term protection to hydro station components and equipment.

Prolonged exposure to corrosive fluids and abrasive particulates erodes unprotected metal surfaces, impacting plant reliability and costs. Chesterton’s metal coatings are formulated to protect equipment and structures providing years of service under the harshest conditions.

Concrete is used throughout a hydropower plant and is prone to damage and attack as a result of operating in the environment. Our concrete coatings are utilized to repair damaged concrete surfaces and protect them against further attack.
