Double Mechanical Seals are suitable where absolute leak-proof sealing is necessary due to the toxic/hazardous/ violatile nature of the fluid. They are combination of two conventional seals installed back to back inside the stuffing box. A compatible clean liquid is circulated between the two seals at a higher pressure then the pumpage product. The inner seal prevents the circulated liquid to enter the system and the other seal prevents if from leaking it to atmosphere. The circulation of the liquid reduces the heat generated on the seal faces. These seals are available in different combinations suiting to service conditions.
This is a combinations of two unbalanced multi spring seals mounted back to back.

For all type of equipment of pumping & centrifugal rotary. The mediums are oil, water, weak corrosive solution. Double face, multiple springs, unbalanced structure & driven by set screw.

The GCC 101 Series Seals are designed to handle clear liquids under normal PV conditions. The Seals have a simple, compact design, are easy to insatll and practically need no maintenance. The seals incorporate robust construction for maximum durability and operational reliability. The GCC 101 Series are unbalanced seals. The rotary unit is of compact design, consisting of multiple springs, dynamic secondary seal ring and a seal face, all accommodated in a retainer.
Multiple Springs are used to avoid distortion at high speeds and ensure uniform pressure on -seal faces under all operating conditions. Secondary Seal Rings are available in various forms such as 'O' Rings, Square Rings, Wedge, etc. and in various elastomers such as viton, neoprene, silicon, Bunna-N, EPT, Teflon, GFT, Grafoil, etc. The mating faces can be of high grade carbon, stellite, tungsten carbide, ceramic, etc. depending on the service conditions.

The mediums are all types of rotating equipment, pumps, mixers, agitators and compressors. To suit industries such as general chemical, oil refining, petrochemical, pharmaceutical, food processing, pulp and paper and waste water treatment.

The GCC 101-B seriesare balanced types seals designed to handle higher pressure applications with the same versatility and reliability as GC 10 I-type. To accommodate the series, a step must be provided on the shaft sleeve to permit a design technique of balancing off some of the hydraulic forces which tend to overload the seal faces.

The mediums are all types of rotating equipment, pumps, mixers, agitators and compressors. To suit industries such as general chemical, oil refining, petrochemical, pharmaceutical, food processing, pulp and paper and waste water treatment.

The Teflon Bellow Seals are unrivalled in their ability to withstand highly corrosive fluids such as acids, alkalis, strong oxidizing/reducing agents etc.
All seal components that come in contact with pumped fluid are chemically inert materials like PTFE, GFT and pure Ceramic. The heart of the seal is the flexible PTFE Below made from virgin grade Teflon. Springs and other metal parts are in Haste alloy-C, Alloy-20 etc. The rotary face is of glass filled Teflon. The Stationery face is pureceramic. These seals are always installed externally.

The mediums are all type of strong acid, oxidant and other strong corrosive mediums.
Externally mounted, single face, multiple springs and driven by pure PTFE bellows. Non-pusher, internal balance structure, fine fluctuate of compensation and reliable seals.
