DAS SEAL

The Compact Seal is a double-acting seal and guide element comprising of a rubber seal, two split support rings and two split bearings, located either side of the seal. The profile seal ring seals in both the static and dynamic range whilst the backup rings prevent extrusion into the sealing gap. The function of the guide rings is to guide the piston in the cylinder tube and to absorb transverse forces. The design provides a compact seal and guide combination for a closed or split installation groove.

It is a combination seals used in hydraulic applications as well as some heavy industries.

The nitrile rubber seal has proved itself to be extremely wear resistant in service. It is designed to be compressed by the housing to ensure a low pressure seal and when pressurised be protected from extrusion damage by the extending lips of the support ring.
A tough flexible polymer is used for the support ring which is scarf cut for assembly and to protect the seal from damage. This type is characterized by a Z-shaped back-up ring which forms a chamber with the elastomer seal ring on the inside and is centered on the outside by the guide ring.

ADVANTAGES:

Good sealing effect, also suitable for holding cylinders.
Capable of installation in closed grooves for reduced machining costs.
Economic sealing and guiding solution.
Simple snap installation

PU LAGGING RUBBER WHEELS

We Veer Rubber Industries is a leading Manufacturer of PU Lagging Roller Wheels in Kolkata. We can provide as per client demand or customizing. Our custom lagging services offer a longer wearing polyurethane material especially suited to new and OEM requirements. Polyurethane is a versatile engineering material that offers a range of hardness, mechanical and thermal properties that can be molded for coating rollers and wheels. It has a high load bearing capacity in tension, compression and shear, exceptional abrasion resistance, and outstanding resilience compared to other materials.

CHEVRON PACKING SEAL

Compression molding is often chosen for medium hardness compounds in low volume production or in applications requiring particularly expensive materials. This process helps to minimize the amount of overflow, or flash created during the rubber molding process.

We are leading Manufacturer and Suppliers of Chevron Packing in Kolkata , India. Chevron packing seals also known as V packing seals are highly adaptive sealing products of standard rubber that comprises of rings of multiple “V” shaped lip seals that have been stacked vertically between reinforced header and compression ring to form a complete packing assembly.

They are assembled with a reinforced backing ring to assist with extrusion resistance and with a compression ring that is used to impart axial squeeze on the chevron packing thereby imposing a transverse strain and energizing the packing. One important benefit of the vee packing is that it can operate under any mechanical situations. “V” shaped rings can be one or more as per requirement. These V shaped intermediate rings are tapered to snap-fit the housing during installation, thus they provide a good seal even at low pressures.

OPERATING CAPABILITIES

They can operate at a pressure up to 5000 psi (344.737) bars.
The operating temperature is in the range of 30 to 150 degree Celsius. The temperature working conditions completely depend on the material used when manufacturing the vee packing.
Reciprocating speed is up to 0.5 meter per second.

VITON RUBBER OIL SEALS

We are manufacturing of Viton O Ring, seals, gaskets, U-seals, Hydraulic seals, Oil Seals in West Bengal, India. Quality tested asper the worldwide standards, these products provide better and error free performance. These Viton Seals & gaskets are mainly applied in automobiles, aircraft and earth moving equipment. As per the excessive demands, Apart from this, it can be availed from us in bulk quantities at affordable price.

Key Use: High fluorine grades offer higher resistance to swell in high octane and oxygenated fuel blends. This give superior performance in Ethanol/Methanol blended gasoline. Base resistant grades offer improved resistance to amine based oil protectants found in new transmission oils. Also, improved resistant to steam for higher temperature services

Advantages: Viton is better able to withstand high temperature, while simultaneously retaining its good mechanical properties. Oil and chemical resistance are also essentially unaffected by elevated temperatures. Compounds of Viton remain substantially elastic when exposed to laboratory air oven ageing up to 200 °C or to intermittent exposures up to 300 °C. Viton grades also resist degradation from a wider variety of chemicals and fluids “ including oils, fuels, lubricants and most mineral acids“ than any other non-fluorinated elastomer. In layman’s terms, that means it provides the best fluid resistance of any commercial rubber. With its low permeability to such a broad range of substances, Viton is known to deliver exceptionally good performance in oxygenated automotive fuels. The rugged characteristics Viton don’t stop there however. Because they also display good resistance to compression, even at temperatures that would make other non-fluorinated elastomers brittle. It is also especially resistant to atmospheric oxidation, sun, climatic conditions, fungus and mould. Furthermore, Viton has good electrical properties (in low voltage, low frequency applications) and low burning characteristics.

VITON RUBBER OIL SEALS

The dome valve seal is also known as inflatable dome valve seal or insert seal. Dome valves are more suitable duties and handling chemically aggressive or high temperature materials. They are widely used on pneumatic conveying systems or applications as diverse as fly ash bagging and dispensing food products into containers. The Dome Valve is unique in its ability to open and close with a tight pressure seal in pneumatic conveying systems for abrasive materials. No other valve can achieve as long of a life in harsh environments like the Dome Valve.

OIL SEAL

Oil seals are rotary shaft seals that close a gap between stationary and moving components and prevent lubricant to escape and thus stop contamination through the clearance. There are different types of oil seals that fit a different application and surroundings and are made out of different materials. The right material and type of oil seal is determined by the application and the medium that will be used with the oil seal. These are used on automotive engines and geared motors primarily to prevent oil leaks at the ends of rotating shafts and the intrusion of dust particles from outside. The word “oil seal” is used to describe these products that seal oil. In addition to preventing fluids, such as lubricants and water, and gases used in mechanical products from leaking at their “gaps,” they also keep dust, dirt and sand particles from intruding from outside. Seals are an indispensable means for sealing machines in a variety of fields, including automobiles, airplanes, ships, train cars, construction machines, agricultural machines, petrochemical plants, and home appliances.
