The centrifuge shell
With a large pharmaceutical centrifuge manufacturers need to specifications of the O - ring, installed in the shell of one of their products.
Sealing problems:
Bear a large centrifugal force of seals, seal has very good mechanical properties.And require seals in a groove will not produce blind Angle, this centrifuge easily cleaned.
Sealing requirements:
- Compatible with harsh cleaning medium, such as various kinds of solvents
- Comply with FDA and USP class VI standard
The solution:
Because the order is small batch, the cost of making a mould specially is unacceptable.Therefore O - ring selected using FlexiMoldTM process.Through this method we have exclusive rights to produce, can be made into O - ring properties uniform is the same everywhere, including in the junction of the seamless and molded O - ring completely consistent, without the need for a dedicated mold.In order to ensure the compatibility with processing medium, determines the Isolast ® J9515.
Results:
In a record in a short period of time provided huge O - ring, one is the same as the compression molding of O - ring, without the cost of the mould.
The coffee machine
Professional coffee machines need modulation 300 cups of coffee per hour.It puts forward high demands on all components, especially their seals.
Sealing problems:
In a professional coffee machine, elements are metals, and household type element is plastic.Hard surface and grinding coffee beans, means that it is easy for seal to rapid wear.A famous professional coffee machine manufacturers work together with our sealing systems (company, to prolong the life of the seal, the target is 100000 times before maintenance work cycle.
Sealing requirements:
- The wear resistance grinding coffee beans
- Fatty acid compatible and processing the medium
- Running in the hot water of 16 bar / 2320 psi pressure
- Tolerance field cleaning (CIP) medium
- The FDA standard
The solution:
To meet the user requirements of wear resistance, the Turcon ® Stepseal ® changed in shape.In addition, chose the FDA standard MF levels of material, the material and processing media compatibility, able to tolerate cleaning medium, and work under high pressure.
Results:
In the experiment, the retrofit Turcon ® Stepseal ® design to achieve the requirements of the work cycle, now has been installed in a variety of models of coffee machine.

Filling machine
There are innumerable driven by piston filling machine filling head.
Sealing problems:
The filler they find fruit grain left in the filler of the elastomer seals used in filling head, this led to the pollution.Due to the reason of the sealing structure, it is difficult to clean up.In addition, the elastomer also adhere to the piston shaft, hindered the piston movement and makes filling action is not stable.
Sealing requirements:
- Good chemical resistance
- Under the scene I P (C) chemical cleaning, and work at up to 150 ° C / 302 ° F steam
- Comply with FDA and USP class VI standard
The solution:
Our sealing systems (type company recommends using Gao Qingjie Turcon ® Variseal ® to replace elastomer seals.Because it can be installed in the existing O - ring groove, so don't need to move equipment.Applying stainless steel spring closed in silica gel, which means easy cleaning and disinfection, no risk of contamination.Turcon ® low friction properties of ptfe base material can prevent starts crawling, even after a long incubation period.The selected Turcon ® F material also meets all the specification of the relevant certification.
Results:
Through the use of type Gao Qingjie Turcon ® Variseal ® to eliminate all the risk of contamination.In addition due to low friction characteristics of the seals, filling the action to improve.

The flange gasket
In today's processing plant, there are thousands of different length of tubes, each joint has a pipe joint.They use the clamping sealing gaskets and O - ring.Although these seals of individual cost may be insignificant, but from the point of view of maintenance and their cost is very high.
Sealing problems:
Keep contact with the medium system, exposure to corrosive cleaning fluid.Processing in the system at a multinational pharmaceutical company seal pipe joint flange gasket damaged very quickly.Our customers hope that through the maintenance period of extend the rules to reduce maintenance costs.But the sealing is not compromise, because any pollution lead to product batch scrap, produces the main cost.
Sealing requirements:
- Tolerance of alkaline and acid cleaning (CIP) medium mixture on the site
- Comply with FDA, USP class VI and 3 - A standard
- Seal life is long, the longer the gap between the prescribed maintenance period
The solution:
Sealing system (the company has many tests have been carried out to determine the best material of the chemicals for field cleaning (CIP).Based on these results, we suggest the customer to switch to ethylene propylene rubber E7502 to create flange gasket
Results:
Change the flange gasket materials, and the results prove that can prolong the life of the seal, and to achieve the goal of increasing productivity and prolong the interval between the prescribed maintenance period.In addition, because E7502 was developed for disinfection purposes, thus reducing the pollution.
The mixing valve
In the use of automation line array processing plant, the mixing valve is the key element.Factory can produce a variety of products, can range from food and drink to the drugs and cosmetics.The mixing valve允许同时加工和系统清洗同时进行，而同时又能防止介质混合。
Sealing problems:
An international leading valve manufacturers and sealing system (company, assist to develop to a new generation of sealing structure of the valve.Because valve requires to work 24 hours a day, the seals to tolerate high levels of live cleaning (CIP) medium and high temperature steam, in addition, there are several seals for dynamic seal.
Sealing requirements:
- All sealing material need to meet FDA standards
- Have good chemical properties, oil, grease, ozone resistance and aging resistance
- Allowed temperature range as high as 200 ° C / 392 ° F
- Tolerance under 100 ° C / 212 ° F, acid cleaning fluid concentration of 5%, and 40 ° C / 104 ° F, the concentration of 5% alkaline cleaning fluid
- Tolerance steam sterilization
The solution:
Sealing system (the company from the initial development stage of the product is with the valve manufacturers work together, through the use of finite element 3 d modelling, we developed for seal identified the best geometry, to achieve the best in comprehensive sealing.We chose the fluorine rubber V8650, because it is with the product and cleaning fluid medium and the chemical compatibility of steam.
Results:
Seal structure has been recommended by batch installed in the valve, used in the condition of all kinds of fluid.Have proved that their tolerance field cleaning (CIP) and the working condition of field disinfection (SIP), prolong the interval between the prescribed maintenance period, and to achieve the highest yield.
Quick connector
Quick joint is widely used on the production line, make the production system more flexible, and make the maintenance and repair faster and easier.
Sealing problems:
An industry leading quick connector manufacturers hope to develop joint for chemicals, and beverage.Past them in a product of the elastomer seals cannot bear these harsh working condition in production line.They came to our sealing systems (company seeking solutions, this scheme should not only resistant to chemicals and steam, and in accordance with the relevant industry standards.
Sealing requirements:
- Good chemical resistance
- Under the scene (CIP) cleaning chemicals and work under the high temperature steam
- Comply with FDA and USP class VI standard
- Small size tolerance
The solution:
According to the cleaning medium, and the operating mode of the ethylene propylene rubber sealing systems company (recommended E7502 or Isolast ® materials of O - ring.
Results:
Through the use of the material of seal, quick joint can effectively clean and disinfect, won't cause the damage of O - ring.This means that the sub vendor's customers will benefit from the life extension element.
