Standards and Regulations

Standards are imperative for consistency across all sectors. Especially with products designed for human consumption, all the required guidelines and certifications must be meticulously followed. Many types of industrial materials are suitable for sealing oil, gas, mines and other particularly aggressive media, but they would not be suitable for the food or beverage processing industries.

Our production and quality processes are independently controlled by the International Organization for Standardization (ISO). We are ISO 9001: 2015 certified, which covers the quality management system for the production of seals and seal kits for hydraulic, pneumatic, rotary and static applications. We constantly focus on improving customer experience to provide the best service & product on the market, with an eye always open to continuous improvement and sustainability.

Chesterton Customseal complies with the highest national and international regulatory standards, including:

FDA
NSF
By drinking water
Pharmaceutical regulations

Material certification can be provided upon request.

Reduce Maintenance, Downtime and Repair Costs. Improve Efficiency Under Harsh Conditions.

Unplanned maintenance, equipment downtime, and energy waste can stress your business as the sugar cane does on your machinery.

Our sealing solutions are designed to ease the operation in dusty and abrasive environments. The advantages are:

Easing excessive wear on the equipment to help bearings and shafts continue to run for longer, which increases uptime and production.
Avoid unscheduled downtime and unwanted shutdowns.
Protects the air from dangerous fumes, which can make the air safer to breathe and reduce the risk of fire and explosion.

Thanks to these benefits, the sugar producer can save thousands of dollars by minimizing downtime, increasing equipment longevity and possibly even insurance payments by reducing workplace risks.

All of our sealing solutions for the food and beverage industry can be used in the following process:

Food resources
Food processing (treatment and preparation)
Packaging

With many years of experience and expertise in food and beverage machinery, we have the solutions you need

Premium Materials

In addition to the choice of the basic sealing material, Chesterton Customseal has a good range of innovative products to offer high-quality and high-performance seals. An example is the development of metal detectable elastomers.
The sealing components produced from metal detectable elastomers provide additional contamination detection screening for the food and beverage industry. Some metals can be detected by metal detection and X-ray equipment in fragments of only 2 millimetres (mm). Considering this, it is more desirable to prevent contamination in the first place – contamination events are often very expensive, with investigations, scrapping of the product, cleaning and replacement of seals and gaskets as required. Chesterton Customseal offers a solution for every challenge.

14K Restriction Bushings

Chesterton® 14K Restriction Bushings are used in rotary equipment to form a barrier between the sealing device in the stuffing box or the pump impeller housing and the fluid in the mixing tank. The restriction that is produced reduces flush requirements and helps to prevent suspended abrasive particles from entering the stuffing box area thus prolonging the service life of installed packing sets or mechanical seals.

19K Wear Rings

Chesterton® replaceable wear rings are the solution to costly cylinder re-machining and repairs for medium- to heavy-duty hydraulic or pneumatic equipment. These split, replaceable wear rings reduce the probability of metal-to-metal contact of moving parts and help prolong equipment life. When installed during the cylinder repair, the risk of recurring damage is significantly reduced.

20KD Face and Static Seals

Chesterton® 20K D-Ring is a continuous compression seal designed for static applications and is often used as an upgrade from conventional face seals or O-Ring designs. That is why 20K D-Rings are interchangeable for O-Ring housing and O-Ring designs with backup rings. 20K D-Ring design provides excellent performance in static applications found in hydraulic or pneumatic equipment including flange and valve control units.

W21K Wiper Seals

Chesterton® positive rake wipers are designed to effectively clean and dislodge foreign matter from retracting rods or rams thus preventing 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 on rods or rams in hydraulic and pneumatic applications.

R22KN Rod Seals

Chesterton® R22KN seals are single-acting, continuous U-Cup designs. The special lip design provides an optimal amount of radial sealing load with excellent tribological and sealing characteristics thus resulting in minimal frictional resistance and low heat generation. Utilization of R22KN U-Cup assists to reduce breakaway force and dynamic frictional force during operation.

R27K Rod Seals

The Chesterton® R27K seal is a single-acting, stacked V-Ring set with a positive rake design to provide optimum operating performance in heavy-duty rod applications. Unlike conventional stacked sets, these designs make contact through the center to enable even loading which minimizes friction and provides a longer sealing life.

30K PTFE Lip Seals

Chesterton® 30K Lip Seals are high-performance PTFE lip seals that are ideal for dynamic rotary seal applications. These seals minimize the risk of penetration of external contaminants from entering the housing and provide excellent sealing service in bearing and gearbox applications which prolongs bearing and equipment service life even in hostile working environments.

30KC Cartridge Multi Lip Seal

Chesterton® 30KC polymer cartridge seals are used in dynamic rotary seal applications. This cartridge design uses high performance, filled PTFE materials proven to withstand the high shear rates, frictional heat, and abrasives common when either pumping high-viscosity products or moving powders.

100 Series Cantilever Spring Design

Cantilever spring energized seals are primarily used in highly dynamic applications for rotary and reciprocating equipment, but they can be used in static applications too, when higher deflection springs are needed. Due to excessive expansion or contraction or wide hardware tolerance, the improved spring and seal deflection capability can be required.

500 Series Stacked V-Ring Seals

High-performance, multi-purpose stacked V-Ring sets are ideal for demanding applications, where the reliability and seal performance are requirements, Further, they accommodate hardware with deep stuffing boxes. These stacked sets are used in both rotary and reciprocating applications and are available in solid and split designs, depending upon application requirements.
