Standard Mechanical Seals

FEP/PFA Encapsulated ‘O’-Rings Gland Packing’s Expanded PTFE Gasket Materials

We Focus On Being The World’s Best

“Standard Mechanical Seal”

“Encapsulated ‘O’Ring”

Manufacturer And Supplier.

In order to do this, we have a two part company strategy;

Vulcan Company Introduction

Background

We have over 28 years experience with

these products

Closely collaborated with a number of

US manufacturers over many years

In addition to utilising in our Mechanical

Seals we became a huge re-seller

Vulcan are considered one of the

Worlds Leading Distributors

Why Choose FEP Encapsulated O-Rings?

They combine the energising properties

of elastomers with FEP's superior

resistance to extreme temperatures

and hostile chemicals.

They overcome the cold-flow problems

associated with solid PTFE rings

They provide a cost efficient alternative

to expensive perfluoroelastomer rings

Background

Size of the market has been

estimated at $80 million

Controlled by a handful of US

manufacturers

Production process is closely

guarded by these manufacturers

Background

Traditional manufacturers have not

been responsive to market demands

Lead times are long and they are not

prepared to hold stocks to meet

customer service demands

Production process is highly labour

intensive

Background

Labour intensive and demanding

production process.

This results in;

High production costs

High staff turnover

Constant re-training

Possible quality/consistency problems

Opportunity

Until recently only one non-US

manufacturer has emerged

They are now US owned

They face the high cost of UK production

and similar staff problems

There has long been a massive

opportunity for a manufacturer who can

produce high quality products with lower

labour costs.

Opportunity

Vulcan purchased a majority stake in

one of the smaller US manufacturers

High volume production plant now

fully operational in our seal factories

in China

Vulcan can now offer exceptionally

high quality products at the world’s

most competitive prices

Vulcan Chem-Rings

Quality Materials

Material quality is vital to the capability, performance and life of a seal.

Vulcan insist the highest possible grades are always specified

Tightest tolerances specified to ensure the same in finished product

Quality Materials

FEP/PFA Encapsulation Complies with

part 177 of title 21 of the FDA

Regulations in accordance with FDA

Regulation 21 CFR 177.1550Meets USP

Class VI requirements Complies to 3A®

Sanitary Standard Number 20-22

Quality Manufacture

Competitor manufacturers did not

publish their production tolerances

They worked to double the AS 568

moulded O-Ring tolerances

They would not even certify these

2. STANDARD KEY CHECKS - ALL SEAL GROUPS - [Tick boxes on completion ] NBV VEL

Check INNER CORE material is correct to code. Ie. FV = FEP Viton FS = FEP Silicon

Check for AIR GAPS between the core and the encapsulation.

Check separation in vulcanized elastomer core join area. Permissible gap of up to 10% of o-ring cross section, only if filled with bonding agent. See picture 1

Check for visible stress crack or pinhole in encapsulation. Automatic rejection. See picture 2

Check for foreign particles on inner core material. Permissible particle size of up to 5% of o-ring cross section. See picture 3.

Check for blooming. Automatic rejection. See picture 4.

Check for carbon deposit imbedded in encapsulation. Automatic rejection. See picture 5.

Check for wrinkled encapsulation. Automatic rejection. See picture 6.

Check for check the surface finish for marks. Please note, there may be a scratch near the join area, this is the “bleed line”, and will not effect the performance of the seal.

3A. SPECIAL CHECKS – MANUAL INSPECTION DETAILS - [Tick boxes on completion ] NBV VEL

INSIDE DIAMETER –

Touch the inside surface of the o-ring with the jaws of the vernier, without gripping or exerting pressure on the ring. Record the reading at this point.

Repeat this procedure twice more at 60 DEG angles to the original position.

Take an average of the 3 readings to obtain the internal diameter.

CROSS SECTIONAL THICKNESS –

Close the jaws of the vernier around the o-ring cross section until just holding the o-ring, not squeezing it. When unsupported, the ring should fall from the jaws of

the vernier.

Take a reading in the horizontal plain, and then in the vertical plain, at the same point on the ring.

Take an average of the 2 readings and check to the required cross-section tolerance.

Measurements are taken at the join area, immediately to either side of the join area, and at a point opposite the weld area.

What is important, is that the average cross-section does not fall below the minimum tolerance specified.(overleaf)

The accepted Industry standard tolerance for encapsulated o-rings for both ID and cross-section is taken as TWICE the BS 1806 tolerance.

However, Q –GRADE o-rings are produced to suit BS 1806 tolerance.

3B. COMPUTER MACHINE INSPECTION DETAILS - [Tick boxes on completion ] NBV VEL

Sample Inspect each Production Size Batch to detail, size and tolerances shown in Sections 3A and 3C. Pay particular attention to the join weld area.

Quality Manufacture

Uniquely in the industry we can offer

seals produced to published close

tolerances in two different grades

Q Grade Produced in line with AS 568 tolerances

Vulcan were the first to offer this

Bleed Line Free Standard As Q Grade but produced with a special

moulding process to ensure an improved finish and consistent section in the weld area

Vulcan Encapsulated O-rings

Vulcan BLEED LINE FREE vs Q-GRADE Production All Vulcan Bleed Line Free & Q grade FEP O rings are manufactured to our tightest, published tolerances.

All Vulcan Bleed Line Free & Q grade FEP O rings utilise the very highest quality Dupont FEP/PFA tubing, Viton

core and industry leading Silicone compound.

All Vulcan Bleed Line Free & Q grade FEP/PFA Tubing comply to FDA, USP Class VI & Sanitary 3A

requirements.

All Vulcan Bleed Line Free & Q grade FEP O rings meet the same Temperature, Pressure, Shore Hardness,

Chemical compatibility specifications.

So why specify BLEED LINE FREE production???

Bleed Line Free FEP ‘O’ rings are produced using a Special Moulding process cycle some THREE times that of

Q-grade FEP ‘O’ rings. It is this moulding process that creates;

1) An exact tolerance Weld Area. This ensures any reduction between the Cross Section and Weld area is

minimised. In our experience, such quality is generally specified in highly critical Chemical and Valve

applications.

2) A Weld area without impression marks. Due to the moulding process of Q-grade FEP ‘O’ rings, an Impression

mark is left within the Weld Area that is commonly known as a ‘Scratch’ Mark. Such mark is present in 75% of

the worlds FEP ‘O’ rings and will not present a problem to most applications. Vulcan Bleed Line Free ‘O’ rings

eradicate such impression mark to deter any potential customer complaints or queries.

The Filtration High Flow, Membrane filter housing has the unique

design of assuring the elements are seated in the mount receptacles

before the closure can be tightened.

This prevents improper reseating of cartridges prior to being placed

into service and also keeps possible system back pressure from

dislodging the elements from their respective seals.

MEMBRANE FILTER

HOUSING

FIBREGLASS ROUND DAMPERS

Round dampers are designed for control of air flow in round ductwork. They have all fiberglass reinforced construction for greater resistance to corrosive environments

Example Application

EMERGENCY VALVE

Emergency Valves have been designed to incorporate maximum safety, high flow, low-pressure drop, easy maintenance and offer a long service life. The simplicity of their design makes them ideal for oil companies and transporters of petroleum products.

Example Application

The Relief Valve is a type of valve used to control or limit the pressure in a system or vessel which can be built up by a process upset, instrument or equipment failure, or fire.
