Mechanical Rotary Shaft Seals. In most applications, the primary function of mechanical rotary shaft seals is to retain the bearing lubricant, avoid leaks and minimize dust, dirt and moisture ingress that can lead to premature failure of the bearing and other system components.
Mechanical seals made with REFEL have longer life, reduced propensity for leakage, and hence less seal failure. REFEL also has the highest thermal conductivity of any commercially available silicon carbide which means any excess heat generated by, for

Mechanical seals are used in the Chemical & Process Industries as seals in rotating equipment, such as pumps and compressors.For example, in a pump, when a shaft rotates, the liquid can leak out between the shaft and the pump casing. In this case, to prevent leakage a mechanical seal would be used, which basically consists of a hard material embedded in the casing and a softer material in the
All Seals also recommends additional high temperature material options, including: Compressed Non-Asbestos, Fiberfrax® Ceramic Fiber, PTFE (Teflon®), Flexible Graphite & Carbon, Nomex®, andKapton®.. Compressed Non-Asbestos Gaskets (Temperatures to 850°F) Compressed non-asbestos gasket materials combine non-asbestos fibers such as fiberglass and aramid fibers with rubber to
Mechanical Seals for Pumps : Rotating Face Mechanical Seals: Mechanical shaft seals are the best way to seal a pump. Face seals prevent leakage better than packing and if selected properly will last longer. Mechanical seals used in clean well lubricated applications can last 20 years.
Mechanical seals has the high demands about sealing materials, so the ceramic is choosed to make ceramic mechanical seal because of its competitive features. Mechanical characteristic Ceramic material is the material with the best rigidity and highest hardness in engineering materials, and its hardness is mostly above 1500HV.
Mechanical seals made with REFEL have longer life, reduced propensity for leakage, and hence less seal failure. REFEL also has the highest thermal conductivity of any commercially available silicon carbide which means any excess heat generated by, for example, dry running, can be dissipated faster than other available material combinations.

Single and double lip radial shaft seals rated for pressures up to 90 psi., mechanical seal mating-rings and shaft packing. Low pressure radial lip seals (less than 3 psi.) and application specific seals not listed are stocked and are available by request. Popular mechanical seal mating rings come in ceramic (white) and sintered nickel-iron (gray).
Aside from these benefits, the PSS Shaft Seal helps to eliminate water in the bilge (100% water tight) and wear to the propeller shaft. Any vessel can easily be retrofitted with a PSS Shaft Seal, and is available for shafts ranging from 3/4” to 6-1/2” (20mm to 150mm).
The higher the temperature, the shorter the time before the o-ring takes a compression set. When an o-ring is exposed to high temperature for a long period, it will become hard and brittle, causing mechanical seals failure. Since heat is often a problem and seldom helps the mechanical seal application, what can be done about it? 1.
Hangup. Loss of axial movement, or seal hangup, is caused when leakage accumulates and hardens beneath the “floating” element. In most seals, this is the rotating element. Hangup is a particularly troublesome problem in high temperature seals because any leakage tends to form “coke”. There are four approaches to solving hangup problems:
We are having range of products like mechanical Seal, Mechanical Seals, conical spring seal, single spring seal, m spring o ring seal, m spring wedge type seal, wedge type spring seal, teflon bellow seal, rubber bellow seal, metal bellow seal, reverse balanced seal, high temperature seal, cartridge seal, double mechanical pump seal, dry running
A few basic components and principles in mechanical seal design contribute to a working seal at the interface of the rotating shaft and stationary pump/mixer/seal-chamber housing. Mechanical seals are usually end-face seals or rotating-face seals, but in some designs they can be circumferential or even a hybrid of lip-type seals.
Tungsten carbide is the most widely used face seal material, and is used as a stationary seat ring for medium and low speed mechanical seals and a rotary face ring for high speed mechanical seals. 2. Carbon --- Carbon has the advantages of good corrosion resistance and self-lubrication, low friction coefficient, good thermal shock resistance
