There are various types of mechanical seals, including contacting and non-contacting face seals. They both operate as a sealing system with a stationary component coupled with a matched axial rotating part.
Non-contacting, or lift-off, seals have unique grooves engineered into the seal rotor that create a pumping action that causes the rotor and seal nose to separate. This separation generates less friction and heat than contacting face seals and provides almost no leakage and a longer life for the seal.
Circumferential seals operate radially instead of axially between the shaft and seal. There are two types of circumferential seals: controlled gap and fractured-ring seals.

The primary purpose of a mechanical seal is to separate air from fluids in rotating applications. Mechanical seals consist of a rotating component, a rotor or mating ring, and a stationary component often called the seal.
The core design consideration is a function of the system pressure and the surface velocity of the rotating component. Our engineers consider the limited physical space constraints, or envelope, the seal must be able to fit into. The media the seal will be exposed to is an issue of utmost concern to the seal''s design. Learn more: https://technetics.c
Technetics is familiar with creating custom sealing solution designs, including those which aren't the typical circular seal form. However, there are design limitations with custom shapes. Reshaping metal seals puts added stress onto the seal, and the size of the designed corners can be a contributing factor.
Since metal sealing solutions utilize plastic deformations of the outermost layer, softer materials are typically preferred, such as aluminum or silver. With plating, we recommend a surface roughness of 16-63 RMS to allow the material to adequately deform. Similarly, if a jacketed material is used, we suggest a surface roughness of 32-125 RMS. The rougher surface finish is desired since there is more material to deform in a jacketed layer than a plated one. We understand some may require a harder material, such as nickel or stainless steel, for higher temperature requirements or chemical compatibility. In this case, we recommend a surface roughness of 16-32 RMS for plated or 32-63 for jacketed seals.
While these numbers are estimations and need to be further verified, it's a starting point to make sure your bolts won't be stretched too much and fail.
While some product lines have 100% recovery, Senior Design Engineer, Ryan Widejko, said most Technetics' metal seals are not considered reusable.
This is due to how the product was designed, which involves a plastic deformation of the soft outer layer - whether plating or soft double jacket - and the cross-section itself.
Widejko intricately draws a live, zoomed-in visual aid to demonstrate why we typically don't recommend reusing metal seals.
This presentation details how the soft outer layer permanently conforms to whatever material it's pressed into. Additionally, the plastic component conforms to the object it's sealing, based on the compression. These pieces work together to create the promised quality of a tight seal.
Metallic seals have a degree of elastic deformation, which occurs in addition to the plastic deformation of the outer sealing material. When decompressed, the seal can still provide sealing until the seal track contact pressure reduces to the point of significant leakage. This elastic recovery can be helpful, even in static systems, since external factors may cause the joints or flanges to separate slightly.
Simulation of seal compression and decompression can enable us to identify the total seal compression and permanent deformation value. The useful elastic recovery value will fall between these two amounts of compression. Quantifying the exact amount of useful elastic recovery a seal can handle is complex and cannot be accurately determined through calculations or analysis. By testing the sealing system, we account for all factors including seal design, system pressure, system temperature, sealing surface finishes, and the required leak rate.
We typically deal with three types of mechanical seals in critical aerospace and industrial applications: contacting face seals, non-contacting face seals and bellows-energized contacting seals. Technetics Qualiseal® mechanical seals are custom engineered to meet the demanding requirements in these situations.
The material mechanical seals are made from dictates their temperature limits. Carbon is good up to 800 degrees Fahrenheit, while secondary seals and typical contact face seals are limited to 300-500 degrees Fahrenheit.
When evaluating mechanical seal applications, we''re interested in the surface speed, not just the rotating speed. Surface speed is a key input when determining the system''s pressure velocity (PV).
We work with applications of up to one million PV. Technetics can customize the seal to accommodate shaft diameters from 3/8" to 10 inches. We also consider the space envelope (the amount of space available for the seal).
