Mechanical seals are mainly used for high speed sealing between liquids and two gases the two surface aids the lubrication of the two surface, conduct heat caused by friction and improve the sealing effect. The diameter of the counter face should be the same or larger than that of the carbon ring. the finish of the carbon wearing surface and of the counter face is critical to the relative wear rate. Counter face : Grey cast iron, plain, steel alloyed steel hard metal, ceramic, glass, tungsten carbide, silicon carbide.

Is impervious to practically all known acids, solvents & corrosives. permits the handling of inflammable and toxic with absolute safely due to complete elimination of leakage. prevents loss of expensive liquids and gases. SivaSeal is available in various range of styles and sizes, can meet space and installation requirements for practically all types of rotary shaft equipment like centrifugal and rotary pumps, mixtures, agitators and autoclaves. special types of seals can be recommended for handling medium/high pressures and temperatures. Spares-Carbon : Metallic and flexible member-can be had ex stock at all times.

Carbon sleeve bearing are employed where oil lubricated bearing cannot be used. Carbon, with its good dry running ability together with excellent corrosion resistance, form retention and resistance to high temp. and sudden temp changes as well as good thermal conductivity, possess an outstanding combination properties for these application.carbon bearing can be pressed into a process of h7/s6 for operating temperature of up to 1500c. the housing or steel ring should be heated up to about 4500c. the housing or steel ring should be heated up to about 4500c for shrinking in.

Packing rings are divided into two types :

Those with shaft clearance (with gaps) and those in contact with the shaft. The contact pressure of the carbon ring to the cylinder is necessary to achieve. A good sealing effect is attained with the use of garter spring, Calculation of spiral tension spring can be based on maximum permissible contact pressure of the carbon ring on the cylinder of 1………1.5n/cm2

Carbon Guide & Seal Ring for Steam Rotary Joints:

Steam Heated Driers And Calenders in Processing Plant of the
Paper Industry
Textile Industry
Rubber Industry
Chemical Industry
are provided with carbon packing ring pressed laterally onto the steam inlet and outlet vents having concave or convex surface, because this design allows the packing ring to adjust to the oscillation of calender drums. Carbon seal attain the surface quality necessary for sealing after a short running in period.

Carbon Graphite Materials

Carbon Graphite Materials are proven applications for the sealing of shafts and their bearing. These rubbing components are widely used in high temperature applications where the presence of liquid lubricants is unacceptable.

What makes SIV SEAL suitable for the most demanding application? A combination of high temperature withstand, chemical inertness, dry running capacity. low density dimensional stability, impermeability to gas and liquid as well as low thermal co-efficient of expansion.

FLOTECH FS FLEXIBLE HOSE :

The flexible hoses are available in various sizes and materials of construction like stainless steel, rubber and teflon to suit various applications.

O-ring is the most commonly used seal within all industries. We offer a wide range of O-Rings that balance cost-effectiveness with performance. Any size of O-Ring is available (metric or inch, standard or custom), including giant O-Rings. If the O-rings you want are not available off-the-shelf, we can supply them within days from our extensive manufacturing facility. With our flexible production schedules, we can meet the most urgent requests from industry.

In addition, wide choices of materials for both standard and special applications allow the O-Ring to be used to seal practically all liquid and gaseous media. These include best-in-class elastomer like Nitrile (NBR), Fluorocarbon (Viton®), Silicon (VMQ), Fluor silicone (FVMQ), Polyurethane, PTFE (Teflon®), Ethylene Propylene (EPDM), Hydrogenated Nitrile Rubber (H-NBR), Carboxylated Nitrile Rubber(X-NBR), Styrene Butadiene Rubber (SBR), Perfluoroelastomer (FFKM), Neoprene (CR).

Back-up rings are the most common anti-extrusion devices in dynamic sealing. They provide simple solutions to safely increase system pressure or solve an existing seal extrusion problem. Back-up rings function by positioning a more robust material adjacent to the extrusion gap, taking the seal’s place and providing a barrier against high pressures. Back-ups can be used to offset the reduced pressure rating effects of wear rings or to improve seal life at increased pressures. They can also be used to protect seals against pressure spikes, or to ensure seal performance at higher temperatures.

Ptfe Backup Ring supplied by Seals is available in the following material specification such as virgin PTFE, which is used mainly for o-rings, backup rings and for machined parts used in special applications requiring chemical inertness and limited strength. Even they are ideal for use in cryogenic applications.

Bronze filled Ptfe is used in dynamic sealing applications, where the bronze filler gives improved wear resistance, hardness and compressive strength. The electrical properties and chemical resistance are reduced. Graphite filled Ptfe has significant increased thermal conductivity, reduced level of creep. They are self-lubricating, therefore suitable for high-speed applications, without the need for exterior lubrication and applications, which need to remove thermal energy and/or static electricity.

Glass filled Ptfe is used, where there is a need for improved wear and increased coefficient of friction. They are ideal for high dynamic applications E.g. High rotation pumps. These high-performance Ptfe seals are said to provide exceptional life, high chemical resistance, and lower friction that versus conventional elastomer seals. Ptfe seal handles wide variations in pressure and temperature and surface speeds.

Features:

Quad Ring Seals are four lipped seals with a specially developed sealing profile. A wide range of elastomer materials for both standard and special applications allows practically all liquid and gaseous media to be sealed.

Advantage:

Quad Rings/X-Rings have the following advantages compared to an O ring:

• Avoids twisting in the groove. Due to its special profile, the seal does not tend to roll in the groove during reciprocating movement.
• Very good sealing efficiency. Due to an improved pressure profile over Quad Ring Seal cross-section, a high sealing effect is achieved.
• A lubricant reservoir formed between the sealing lips improves start up.
• Unlike an O-Ring, the mould line flash lies in the trough, between and away from the critical sealing lips.

Advantage:

Bonded seal is a static seal which are used as a sealing ring fitted under bolt head & nuts are used in Hydraulic & Earth Moving Machinery.
