Mechanical seals are critical components in centrifugal pump systems. These devices preserve the integrity of the pump systems by preventing fluid leaks and keeping contaminants out. Mechanical seal systems are used on various seal designs to detect leakage, control the seal environment and lubricate secondary seals.

Depending on the pump type and the process variables, there are various mechanical seal types to choose from. Each seal variant has its unique design and characteristics which make it suitable for a specific application. MES has years of experience with industrial mechanical seals and support systems, making us an authority in this area.

Mechanical seal types vary in design, arrangement, and how they disperse the hydraulic forces acting at their faces. The most common seal types include the following:

Balanced mechanical seal arrangements refer to a system where the forces acting at the seal faces are balanced. As a result of the lower face loading, there is more even lubrication of the seal faces and longer seal life. Learn about our mechanical seal lubrication systems today.

Balanced mechanical seals are particularly suited to higher operating pressures, typically above 200 PSIG. They are also a good choice when handling liquids with low lubricity and higher volatility.

Unbalanced mechanical seal types are commonly employed as a more economical option to the more complex balance seal. Unbalanced seals may also exhibit less product leakage due to tighter control of the face film, but as a result can exhibit much lower mean time between failure. Unbalanced seals are not recommended for high pressure or most hydrocarbon applications.

Pusher seals utilize one or multiple springs to maintain seal closing forces. The springs can be in the rotating or stationary element of the mechanical seal. Pusher type seals can provide sealing at very high pressures but have a drawback due to the elastomer under the primary seal face that can be subjected to wear as the face moves along the shaft/sleeve during operation.

Non-pusher seals utilize a metal or elastomeric bellows to maintain seal closing forces. These seals are ideally suited to dirty and high temperature applications. Bellows seals are limited to medium/lower pressure applications.

Conventional seals are typically lower cost and often installed on general service equipment. These seals require higher operator skill to service as they installed as individual components.

Cartridge type mechanical seals incorporate all of the seal elements into a single assembly. This dramatically reduces the potential for assembly error and the time require for seal replacements. Learn more about the difference between cartridge and non-cartridge mechanical seals today.

When deciding on the type of seal system for a centrifugal pump, operators must choose according to their unique application. Failure to select the proper seal type can lead to loss of pump integrity, breakdowns and costly repairs. To avoid these undesirable results, all operators must consider the following factors before deciding.

The amount of pressure exerted at a mechanical seal’s faces has a significant effect on its performance. If a pump is to be operated at low pressures, an unbalanced mechanical seal will be suitable. However, in conditions where higher pressures are anticipated, balanced seals will prove a more reliable solution.

Balanced mechanical seals perform better than their unbalanced counterparts in conditions where the operating temperatures are higher than normal. Heat sensitive components are better preserved in balanced mechanical seals compared to other seal types.

As it goes for all types of machinery, operator safety is the top priority. The use of double mechanical seals in centrifugal pumps provides additional protection as they have increased sealing capacity and are generally more reliable.

Amechanical seal is the most common type of sealing component used on pumps in modern industry. Replacing out packing over the last 50 or so years, they have served to drastically reduce industry emissions, energy usage and downtime globally.

A mechanical seal for pumps can be subdivided into variable options depending on the type/specific application/design components/location and mechanical seal characteristics;

The major advantage of a cartridge seal over a component seal is ease of installation. Incorrect installation is a major cause of seal failure, cartridge seals remove many of the problems associated with seal change-out in the field.

Slurry Seal – mechanical seal engineered to cope with a heavy slurry process – i.e. abrasive, corrosive and viscous. Can handle up to 60% slurrys by weight.

A Pusher Seal is where there is a spring element in the seal (used to maintain contact of the seal faces). Spring types include Belleville, multi-spring, etc. This type of seal requires a dynamic secondary seal.

A gas seal is a double seal where the barrier fluid is a gas – in pumps, this is usually a gas lift-off seal. In a gas lift-off seal the faces are not in contact while the machine is running. They are separated by a thin gas film (flow). If operated correctly they have very low wear.

The above seal types can be combined (though it is not always best to do so i.e. a component gas lift off seal would require very close collaboration between the machine and seal manufacturers to achieve a reliable installation).

There are many other options for mechanical seals, if you have any technical queries on other combinations not listed above,  just contact one of our Mechanical Seal Specialists who will gladly discuss your application.

A mechanical seal flush is a piping set-up on a pump and seal assembly where a flow is induced in the seal chamber in order to improve MTBF of the mechanical seal. It is used to improve cooling, heating, remove solids and increase pressure (in combination with a neck or throat bush).

A mechanical seal quench is a piping set-up where a fluid is piped over the atmospheric side of a seal. It is generally used to prevent precipitation or crystallisation of a product or in some cases to aid cooling.

High Slurry process using Flowserve’s UNCD ® – Ultrananocrystalline diamond  seal face technology. Flowserve UNCD ® coatings offer material properties and performance advancement over all other seal face materials.

Slurry seal design expertise applications which previously required double mechanical seals can now be reliably run by using single mechanical seals, saving costs of barrier fluid systems, the costs of the barrier fluid itself & the associated running costs. This reduces energy usage & carbon footprint.

Mechanical seals are designed to preserve the integrity of the pump system. They prevent fluid leaks and maintain a proper pressure seal within any centrifugal pump. The rotating shaft enters the back end of the pump casing by way of a stuffing box or seal chamber. To achieve better performance, safety, and durability, it is critical to select the right size and type of mechanical seal for your specific centrifugal pump, as well as for your pump application.

Mechanical seals feature two flat and smooth seal faces that work in unison. One will rotate with the shaft while the other remains stationary with the pump casing. Each seal face is connected to its respective halves with secondary seals, such as gaskets or o-rings. Mechanical seals can provide sealing flexibility to adjust for any slight misalignments while reducing potential wear on the various components.

Proper lubrication is key for healthy mechanical seals. The lubricating fluid will actually break down during operation, which creates a small release of vapor. It is natural and necessary for this vaporization to occur in a correctly functioning mechanical seal. Lubrication is an important step during mechanical seal installation and ongoing maintenance. Inspecting your mechanical seals is vital, and they should be adjusted, relubricated, or replaced as needed to keep your centrifugal pump leak-free.

There are several key steps for installing a new mechanical seal on your centrifugal pump. You will first need to shut off the pump motor and disconnect the power supply to ensure it cannot start up during maintenance. Then, all process fluid should be isolated and then drained from the pump housing.

Different centrifugal pump designs will have different ways to access the mechanical seal, some may be more complex than others. Consult the owner’s manual and follow the necessary procedures to safely access and remove the old mechanical seal. The impeller will also need to be removed during this stage. Ultimately, you will be able to remove both the rotary and stationary mechanical seal halves.

Make sure everything is clean and properly aligned during the installation of a new mechanical seal. Which mechanical seal is best for your pump may depend on a number of factors:

There are a wide variety of mechanical seals for centrifugal pumps from leading manufacturers like Flex-A-Seal, John Crane, Flowserve, and more. They are available in different sizes and configurations, as well as unique construction and coating materials to handle various process fluids.

Chemicals and liquids with acidic or corrosive qualities may call for a more robust mechanical seal made of a certain abrasion-resistant material. A standard seal solution may be adequate for less-aggressive fluid applications. It is very important to understand your application when it comes to selecting the best mechanical seal.

Once the mechanical seal is installed and everything is put back in place with proper alignment, you can refill and restart the pump. Monitor it carefully, it is working properly and there are no fluid leaks coming from the new mechanical seal. Test and adjust as much as necessary before running at full capacity. Continue to monitor and maintain your mechanical seals and all pump components for reliable performance and extended equipment lifespan.
