Rubber Bellow Mechanical Seal 

Rubber Bellow Mechanical seal  are most commonly used rubber bellow seal, Due to its compact design it can be easily mounted. It has a unique rubber bellow secondary seal, which provides a high degree of axial flexibility to compensate for lack of concentric of the shaft misalignment wear due to thrust movement of the shaft. The seal can be use regardless of direction of rotation since the driving torque is not transmitted through the coil spring, The required driving torque is enhanced through the unique rubber bellow which fits on the shaft. There are no bonded Joints and all the face materials are interchangeable without having to modify any dimensions.

 

Applications :
Generally used in sewage applications, waste water pumps fuel injection pumps.

Cartridge seals are self-contained units consisting of a shaft sleeve, seal, and gland plate. The unit is fitted onto the pump shaft as a built assembly, and no further fitting is required. Cartridge seals are an attempt to over-come the fitting problems of conventional seal, They are supplied in

single and double form, and the gland plate is often fitted with various tappings to provide for flushing, cooling water injection, and disaster control. The cartridge can overcome several limitations of the standard pump gland. Tangential tappings for introducing fluids into the gland cause less disturbance to the seal face than the radial tappings often found on pump units. Look again at the tapping provided for flush water to the packed gland, a tangential tapping would provide a less turbulent water source. For a packing gland this may not be important but to a mechanical seal it can be another adverse condition with which to cope.

The setting position of the seal is set by the cartridge design, but the seal unit should not be screwed to the shaft until the gland plate is secured to the pump and any adjustments made to the shaft position. Once this has been completed the set screws can be tightened and the spacers removed.

So, what can go wrong. The design works to eliminate many of the common causes of seal failure on installation and because the seal is presented on its own shaft sleeve any damage that might be caused by a conventional seal to the pump unit is also eliminated

The seal contains the secondary seal, the ‘o’ ring. The face materials and elastomers can be varied as per requirement of the application. The conical helical springs transmits the torque. The seals depend on the direction of the rotation. The conical helical spring can be fitted easily by pushing on the shaft and twisting as the spring winding. So, the spring diameter enlarges easily to make easy fitting. One can judge the direction of the rotation from the drive end of the shaft. The clockwise rotating shaft requires the right handed spring and anti-clockwise rotating shaft requires left handed spring. The conical single spring unbalance seals are used in central heating system in circulation pumps. It’s also used in the chemical process pumps, sewage and submersible pumps and chemical process pumps.

Silicone rubber since its discovery has been used for a wide range of applications. One such sector in which it has been extensively used is Pharmaceuticals. Because of its chemical inertness, Food grade properties and its transparency, It became one of the favorite choices in the selection of polymeric raw materials. We provide the Silicone Inflatable Seals to the clients. Some of the main unit processes in the production cycle of any pharmaceutical industry include granulation, blending, Drying, coating etc. In the process of Drying these companies use machines called as Fluidized Bed Dryers (Also known as Fluidized Bed Equipment acronym: FBE) or more commonly known as FBDs. Coating processes make use of the Machines called Coaters. All of these machines are made of various grades of stainless steel. From time to time these machines have chambers, which have to be cleaned to start another batch, change filter bag or sometimes just for maintenance shut down. Hence these machines are never in one piece but generally have openings. The thing about these openings is that even when they are in operation they create contamination by bringing in the outside atmospheric air.

One thing common about all of these machines is that they need to be 100% contamination free. That implies, no atmospheric substance including air can come in contact with the product being processed. Hence a new Innovative polymer product was manufactured to give 100 percent sealing between contacting metal parts in the FBD machines. These were called Silicone inflatable seals. These were called so because of their unique properties that made them different than regular seals. These seals can inflate and seal all nooks and corners perfectly so as to give 100 percent sealing even when the machine is pressurized. Platinum Cured Transparent silicone inflatable seals are used on fluid bed dryer as well as fluid bed processors FBP in machines of capacities from 25 kg to 1500 kg.

These Silicone Inflatable seals or gaskets are classified into

A) Based on machine design

1) Top Gasket

2) Filter Bag gasket

3) Bottom Gasket


B) Based on Nozzle placement on gasket

1) Nozzle on Inside (on ID) of gasket

2) Nozzle on the outside (on OD) of gasket

3) Nozzle on the top of gasket

4) Nozzle on the Bottom of gasket
