mechanical seal manufacturers in usa in stock

Mechanical seals are intended for applications in which a rotating shaft and its housing are under a state of stress, including a combination of high pressure, temperature, and speed.

Most mechanical seals are specially designed to prevent leaks in particular applications and cannot be interchanged with those seals used in other mechanisms. A piston seal, for example, cannot be used as a flange gasket; they are shaped differently, made out of different materials, and feature different mechanical properties of a given mechanical seal always depends on the conditions in which it will be applied.

Also, depending on the narrowness or broadness of a given understanding of the words “mechanical seal,” certain kinds of seals may or may not qualify. Simple plastic lids qualify by the broadest definitions, while some of the strictest definitions might only include seals applied in industrial process equipment or in heavy machinery. In either case, mechanical seals perform the same task: to isolate and contain materials in an enclosure.

Correctly pairing seals with their applications is essential to the safe and effective use of the equipment in which they are installed. For example, Teflon is often chosen for use in hydraulic cylinders because it is resistant to corrosion induced by exposure to hydraulic fluids. Natural rubber, on the other hand, may degrade when exposed to such chemicals. The decision to employ a given seal material should always be chosen carefully; this will ensure sustained effective and safe operation of the seal and the equipment it protects.

Mechanical seal varieties are used to prevent the unwanted release of pressure, lubricants, hydraulic fluids and other properties of a system that makes use of them. Seals are also used to prevent the contamination of those systems by dirt and other hazards. Equipment like agitators, mixers, gas seals, pumps, valves, actuators and many other kinds of machinery all involve the use of some variety of mechanical seal.

In addition to preventing leaks, mechanical seals also keep contaminants from entering and help to maintain pressure levels. Piston seals, flange gaskets and diaphragm seals are also kinds of mechanical seals, and they are all essential to the functioning of certain kinds of equipment.

Most mechanical seals are specially designed to prevent leaks in particular applications and cannot be interchanged with those seals used in other mechanisms. A piston seal, for example, cannot be used as a flange gasket; they are shaped differently, made out of different materials and feature different mechanical properties. The shape, size, and composition of a given mechanical seal always depends on the conditions in which it will be applied.

Power machines that have a rotating shaft, such as pumps and compressors, are generally known as “rotating machines.” Mechanical seals are a type of packing installed on the power transmitting shaft of a rotating machine. They are used in various applications ranging from automobiles, ships, rockets and industrial plant equipment, to residential devices.

Mechanical seals are intended to prevent the fluid (water or oil) used by a machine from leaking to the external environment (the atmosphere or a body of water). This role of mechanical seals contributes to the prevention of environmental contamination, energy saving through improved machine operating efficiency, and machine safety.

Shown below is a sectional view of a rotating machine that requires the installation of a mechanical seal. This machine has a large vessel and a rotating shaft at the center of the vessel (e.g., a mixer). The illustration shows the consequences of cases with and without a mechanical seal.

If the aim is solely to prevent leakage from the machine, it is effective to use a seal material known as gland packing on the shaft. However, a gland packing tightly wound around the shaft hinders the motion of the shaft, resulting in shaft wear and therefore requiring a lubricant during use.

Separate rings are installed on the shaft and on the machine housing to allow minimal leakage of the liquid used by the machine without affecting the rotating force of the shaft.

To ensure this, each part is fabricated according to a precise design. Mechanical seals prevent leakage even with hazardous substances that are difficult to mechanically handle or under harsh conditions of high pressure and high rotating speed.

A mechanical seal is installed on the impeller rotating shaft. This prevents the liquid from leaking through the clearance between the pump body and the shaft.

The rotary ring rotates with the shaft. The stationary and rotary rings rub against each other ensuring a clearance in the order of micrometers maintained between them. Where they rub against each other, they are referred to as “face materials.”

The face materials where the stationary ring and the rotary ring rub against each other are the most important portions as a barrier to the fluid. If the clearance is too small, the friction increases, hindering the shaft motion or resulting in seal breakage. Conversely, if the clearance is too large, the liquid will leak. Consequently, it is necessary to control the clearance in the order of micrometers to prevent leakage, but at the same time ensuring lubrication by the fluid, thereby reducing the sliding torque and avoiding hindrance to the machines’ rotation.

The mechanical seal technology is a sum of mechanical engineering and physical property technology due to the above-mentioned functions and applications. More specifically, the core of the mechanical seal technology is the tribology (friction, wear and lubrication) technology used to control the surfaces where the stationary and rotary rings rub (slide) against each other.

Mechanical seals with improved functionality will not only prevent the liquid or gas handled by a machine from leaking to the outside, but also improve machine operating efficiency, thereby helping achieve energy saving and prevent environmental contamination. Moreover, in some cases, rotating machines handle media that, in the case of leakage, can lead to a dangerous accident. Therefore, mechanical seals are required to be highly reliable through manufacturing backed by solid engineering expertise.

These functions and roles will make mechanical seals increasingly important functional parts in the future. Their further technical innovation is anticipated. To positively respond to these expectations, Eagle Industry is working on technical research and development every day.

The mechanical seal technology was fundamentally established in the 1960s. Thereafter, it has been making significant progress by introducing various leading-edge technologies, and innovative mechanical seals created from the above advanced technology are continuously being put to practical use.

To meet the demands of the market sufficiently, an applicable range of the “pressure” and “rotation speed” of mechanical seals has been considerably extended since the beginning of the 2000s. This is due to advancing of the tribology technology such as to enhance a function of the sliding materials (e.g., composite material composition, coating technology) and/or a performance of the sliding surfaces based on the fluid lubrication theory (e.g., non-contact mechanical seal, surface textured mechanical seal). These advanced technologies are sustained by improvement in the element technology of numerical analysis, processing/production, physical property/composition analysis, measurement, verification test, and so on.
