KRISH CARBON GRADES
Krish Carbon Seal Rings are either resin impregnated or metal impregnated or highly densified carbon form based on the specific customer requirements. As an end-to-end carbon company, Krish Carbon grades and configurations is precision matched to suit your specific needs. Seal rings are custom designed to deliver fluid & gas seal, while also offering excellent performance at high pressures. They are carefully crafted from raw material to machined final product. Krish Carbon materials complies with varied requirements, such as FDA, WRAS. Precision production processes ensures tightest of tolerances in seal rings.

Krish Carbon Thrust bearings are either resin impregnated or metal impregnated form, based on the specific customer requirements. They are designed and validated to withstand the required thrust load.

Krish Carbon Thrust Pads are manufactured for submersible motors to meet the dynamic | varying load conditions of bore-wells and for open well vertical | horizontal pumps. Starting from 0.5 HP and up to 200 HP, Thrust bearings are designed to suit submersible motors from 3 Inches to 12 Inches for thrust loads ranging from 5kN to 100kN.

CARBON THRUST BEARING FEATURES

High Wear Resistance
Lower Co-efficient of Friction
Self-Lubricating
Low Thermal Expansion
Low Thermal Conductivity
Self-aligning segments to withstand fluctuating loads

Improved efficiency due to the inherent properties of Krish Carbon. Precision matched to suit your specific needs. Perfect combination of high hardened, lapped and polished Stainless steel segments results in longer life, High performance & efficiency.

CARBON RADIAL BEARINGS

Radial Bearings made of Carbon-Graphite resin-impregnated or metal-impregnated Krish Carbon to deliver friction free performance specially for submersible motors requirements. The overall efficiency is substantially improved due to low coefficient of friction and also brings down the starting current of the pumps.

KRISH CARBON FEATURES

Facilitates wet / dry run of motors & pumps
Low heat generation
Better load bearing
Zero maintenance

As an end to end carbon company, Krish Carbon grades and configurations are precision matched to suit your specific needs. Radial Bearings are custom designed to deliver friction free performance.

CARBON VANES

Krish Carbon Vanes offer high mechanical strength and can withstand very high peripheral speeds.
Carbon-graphite vanes and graphite resin bonded vanes made from Krish Carbon are suitable for wet and dry running for vacuum pumps. Specific grades of materials are manufactured for high volume production of complete vane pumps.

INDUSTRY APPLICATIONS

• Printing machines
• Packing machines
• Pumps delivering fresh air
• Gas analysis pumps
• Brake Servo
• Pneumatic tensioning devices

CARBON ROTORS & VANES

Krish Carbon Rotors & Vanes offer high mechanical strength and can withstand very high peripheral speeds. They are Maintenance Free.
Rotors & Vanes made of Krish Carbon-Graphite are suitable for dry running rotary compressors and vacuum pumps. Specific grades of materials are manufactured for high volume production of complete vane pumps.

INDUSTRY APPLICATIONS

Automobile central pneumatic system
Brake Servo
Pneumatic tensioning devices

CARBON STEAM JOINTS

Carbon Steam joint seals water, steam and oil.
Further, it neutralises swing, pendular and tumbling motion. This functionality is normally achieved with a concave or convex seal ring surface which is pressed against the sealing surface with a spring. Certain configurations also have a cylindrical wearing surface. Steam Joints are exposed to all known lubrication conditions including wet, mixed and dry running.

TYPICAL INDUSTRY APPLICATIONS

Paper and Pulp Industries
Textile Industries
Food Processing Industries
Pharmaceutical Industries
Chemical Industries
Cigarette Industries
Compressors
Fuel Dispensing Pumps

MOTION CONTROL RINGS & SEGMENTS
Motion Control Rings and Segments regulate automated production processes. Applications include cigarette production equipment and packaging machines. The use of Carbon-Graphite eliminates oil based lubrication, an important advantage as the intermittent swivelling motion usually precludes the use of a hydrodynamic lubrication system.Carbon Graphite – Resin Impregnated for medium pressure: 8 – 14 kg/cm² and temperature upto 200°C, Carbon Graphite – Metal Impregnated for high pressure / high temperature up to 350°C and pressure

CARBON SEGMENTED RINGS

Segmented Rings can be classified as Contact Seals, Contact Free Seals & Grooved Split Seals. Multi segmented seal rings find extensive use in rotating shafts or linear motion pistons. The number of segments is dependent on the diameter of the shaft. There is no limit to the number of segments.

PISTON ROD SEALS

Piston Rod Seals are used to seal the linear movement of the Piston Rods. Segment rings are used in pairs to achieve additional axial sealing. The segments have overlapping shoulders. Pins or springs secure the rings in position. The shaft’s surface roughness should be Ra 1 µm.

LABYRINTH SEALS

Labyrinth Seals made with Krish Carbon self-lubricating materials have the advantage over metals in those short periods of contact during start-up due to difference in the co-efficient of thermal expansion do not cause damage. As a result, the Labyrinth gaps can be smaller in size on a Carbon Graphite Seal as compared to a Metal Seal. Consequently, given the same performance requirements, a Carbon Graphite Seal can be shorter than a Metal Seal.
