Kaplan Blade Runner Seals

Chesterton Customseal’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 minimise environmental concerns. The bi-directional seal design allows for precise positioning of blades while sealing the hydraulic fluid in and river water out.

Interlock design seals oil in and water out
Proprietary low friction polymer enables accurate blade positioning
Split design minimizes turbine downtime and maintenance costs

Polymer Seals for Wicket Gates

Chesterton Customseal experts have developed tailored sealing solutions, for wicket 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 cold water service use.

High-integrity, reliable sealing for slow, rotary, oscillating applications
Unique designs eliminate continual adjustments
Durable polymer material compensates

Chesterton Kaplan Turbine Runner Blade Trunnion Split Seal

Proven in applications around the world, this split seal design greatly enhances reliability by keeping water and contaminants out of the hub and keeping lubricants in to avoid environmental contamination. Chesterton’s Kaplan Turbine Runner Blade Trunnion Split Seal has a pin and lock design that keeps the turbine motion from pulling the split seal apart and also uses load pressure to join cut ends.

Chesterton R11K Rod & Piston Seal

The Chesterton® 11K Rod Seal is a single-acting, two-part unit recommended for use in hydraulic cylinders and presses. The unique, split design eliminates the need for equipment disassembly and shimming. The simplified design reduces friction and wear as observed in conventional elastomer V-ring assemblies. The net effect is an improvement in the life of the equipment. The bottom ring is the primary sealer while the top ring provides secondary sealing and works as an anti-extrusion ring.

Chesterton 20KD Face & Static Seal

Chesterton 20K D-Ring is a compression seal most commonly designed for use in static applications and often applied as an upgrade from conventional face seals or O-ring designs. This design provides excellent performance in applications found in hydraulic or pneumatic equipment, including flanges and valves control units. Our unique manufacturing process allows the flexibility to create any size seal, making it applicable to nearly every equipment application.

Chesterton 21K Wiper Seal

This positive-rake wiper is designed to effectively clean and dislodge foreign matter from retracting rods and rams to prevent scoring and system contamination. The sharp, rugged, flared profile provides protection against abrasive particles which can contaminate the system and lead to premature equipment failure. These wipers provide excellent performance for hydraulic and pneumatic applications.

Chesterton 22K Rod & Piston Seal

Chesterton 22K Rod & Piston Seal is a single-acting u-cup design with a special seal-lip geometry that provides zero leakage throughout the entire operating range. The sturdy static lip stabilizes the seal to prevent rolling while the negative-rake design eases installation. This seal design is offered as a rod or piston seal and provides excellent performance in hydraulic applications. Our machining process allows the flexibility to create any size with no tooling cost.

Chesterton 22KE Rod & Piston Seal

A single-acting, continuous u-cup design that incorporates the use of an O-ring to increase pre-load capabilities for low pressure. The O-ring energizes the seal—increasing its pre-load capabilities in the absence of system pressure. This seal design is offered as a rod or piston seal and provides excellent performance in hydraulic applications, eliminating low-pressure leakage. Our processes allow the flexibility to create any size seal based on your needs.

Chesterton 22KN Rod & Piston Seal

This seal design offers a positive-rake lip profile for optimal radial sealing load with minimal frictional resistance. This seal is offered as a rod or piston seal and provides outstanding performance in both hydraulic and pneumatic applications. This abrasion-resistant design offers outstanding performance in hydraulic and pneumatic applications, and due to our machining process, we can create this seal in any size!

Chesterton R22KN5 Split Rotary Seal

Chesterton R22KN5 Rotary Split Seals with their robust design are ideal for low-speed dynamic rotary seal applications exposed to large shaft run-out. These seals provide excellent sealing and protective solutions for heavy-duty rotating equipment even in severe application conditions thus prolonging bearing and equipment service life. The flexible, dynamic lip of R22KN5 creates a positive, leak-free seal.

Chesterton 27K Rod Seal

The Chesterton 27K Rod Seal is a single-acting, stacked V-ring set with a positive rake design to provide optimum operating performance. Unlike conventional stacked sets, these designs make contact through the centre to ensure even loading, longer sealing life, and minimal gland pressure. These sets are available in split or solid designs and provide excellent performance in closed-cavity hydraulic applications.

Chesterton WR Custom Wear Rings

These wear rings reduce radial movement, therefore helping to extend seal life. The exceptional physical properties make them suitable for use on rams or pistons in reciprocating and rotary applications. Various designs and materials are available which address specific needs and applications in the market. With the flexibility to make any size seal, we can custom-make these wear rings to eliminate modification.
