Why Are Mechanical Seals Still The Preferred Choice In The Process Industries?

Mechanical seals are the most efficient means of avoiding fluid leakage from the centrifugal pump to the external environment. Mechanical seals help keep the moving portion of the Mechanical shaft seals for pumps from coming into contact with the pump housing’s stationary part. On the other hand, mechanical seals are the devices that form the packing between the rotor and the fixed portion of centrifugal pumps to prevent the fluid from being pumped by the pump from leaking out. The mechanical seals are divided into two parts: the stationary part, which is connected to the pump housing, and the rotating part, which is connected to the rotating shaft.

Most mechanical seal suppliers prefer mechanical seals because they are suitable for a wide range of applications. They have five distinct advantages over traditional packed stuffing boxes.

Reduced Friction

A film of fluid is kept on the faces of mechanical seals to keep them lubricated. This, combined with the ideal spacing between the ears, reduces friction, resulting in less power loss.

No Product Leakage.

Mechanical seals‘ primary function is to keep pumped fluid from leaking. Although there is some space for error, this can be avoided with proper installation and ventilation.

Elimination of Excessive Wea

An adequately installed mechanical seal can assist in the protection of your equipment. Precise alignment, impeller placement, and other instructions are in place, providing stability and extending the life of your equipment.

Reduced Maintenance

Mechanical seals are highly durable and easy to fix when properly align and at the proper temperature. The cost of repairing a mechanical seal is also minimal.

Cost-Effectiveness in the Long Run

Fewer fluids lost in leaks translates to more significant cost savings due to less waste, fewer pump failures, and more straightforward maintenance. They also reduce the risks to pump operators and the health, protection, and environmental benefits that come with them.

Reduced Power Consumption

When compared to gland packing, trisun mechanical seals use less energy. The bulk of gland packing uses six times the amount of energy as a balanced mechanical seal. Will this affect your fuel usage? Of course, it would, and densely packed glands would significantly raise power costs. Pumps may be made to operate at a lower speed and efficiency in certain situations, raising prices even further.

Sustains High Pressure

Mechanical seals can withstand high fluid pressures and highly corrosive fluids. There is still some leakage from compressible packing, and they often fail due to the degrading effects of chemicals, but mechanical seals do not have these issues.

Wearing the Shaft/Sleeve

Trisun mechanical seals with proper design do not need costly shafts or sleeves. Most rotating equipment is equipped with repairable wear sleeves in the region of the gland packing to address the fact that gland packing is built to wear the shaft in this field. The shaft would need to be replaced or rebuilt in the worn area if a replaceable sleeve was not installed. This will be costly in terms of spares me as shafts are repaired.

If a different wear sleeve is used, there is the expense of keeping a replacement on hand. Still, there is also the risk that the shaft diameter under the sleeve has significantly been decreased to allow for fitting, reducing the shaft’s bending resistance significantly.

Choosing the right sealing solution for your application necessitates careful consideration of your pump’s requirements. If you’re unsure which seal is best for your pump and budget, talk to a reputable mechanical seal supplier or your pump manufacturer about your options. They’ll be able to assess your needs and recommend the best seal for your job.
