RCPL offers mechanical seal faces, which are designed to prevent leakage between a rotating shaft and its housing under conditions of extreme pressure, high shaft speed and temperature.

Alumina is commonly used as a mating ring together with carbon-graphite opposing seal face. Alumina exhibits high hardness, good abrasion resistance, high strength and stability.

This makes alumina ceramics suitable for high load, varying shaft speed and high temperature applications. Also provides longer service life and operating safety.

Eco Alumina : With a very innovative idea, we have introduced High-Alumna seal faces with slightly low Alumina content for cost effective seal faces.

Carboneless water pumps are a great, and, of the same design as any electric water pumps. These water pumps are amazing, they are high efficiency and have a long lifespan. On the other note, carbon electric water pumps are amazing, they are high, and high efficiency.

CoorsTek mechanical hard face seal components are engineered specifically for the individual applications. By controlling the manufacturing of seals from the raw material composition to the high-precision finish, CoorsTek maximizes product quality for long-lasting performance in demanding environments.

Mechanical face seals are a complex combination of materials and design that form a system whose prime objective is maintaining the integrity of the pumping system, keeping what is inside where it belongs and preventing contamination from the outside.

These systems enable relative motion between stationary and rotating components while simultaneously accommodating some level of axial or radial movement. The technology that has been developed and implemented in these systems has become so reliable that mechanical seals are often taken for granted. The vast majority of failures of mechanical seals can be attributed to the system in which the seal is installed, not the seal itself.

One of the materials used in many mechanical seal systems is based on the fourth most common element and the basis of all life—carbon. This article will explore how this common element plays such a critical role in these complex systems.

Because mechanical sealing systems must maintain tightly controlled contact between one rotating and one stationary face, interface stability must be maintained across a potentially wide spectrum of conditions. Face flatness is critical and is measured in millionths of an inch; unexpected distortion will change the interface dynamics significantly. With the proximity of the two face materials, contact is inevitable and the materials must be able to operate with some level of self-lubricity so they do not damage each other, which would create a path across that interface that enables system leakage.

There are eight allotropes of the carbon element (see Figure 1), based on how the carbon molecules align in the lattice, that result in a range of properties from the softest version, graphite (often used in pencil “lead”) through amorphous carbon to diamond, the hardest material known to man.

Each company creates a unique recipe intended to address specific conditions that maintain the interface stability; from low temperatures (cryogenic), to water, to methane, to oil, to higher temperatures and beyond, materials exist to provide the needed capability. These materials are designed for specific conditions. One recipe cannot perform in every condition, and seal companies work with material manufacturers to provide the optimum candidate for the application.

Figure 3 shows the variation in physical properties, thermal conductivity and chemical resistance of the part according to the relative amount of carbon and graphite in the finished product.

The attributes of the allotropes, or the various forms of carbon, can be combined in specific ratios and leveraged to achieve desired responses in a system where there is relative motion between two components in terms of friction and wear, (a.k.a. tribology), along with a large temperature range and the need for corrosion resistance. Carbon is an ideal seal face material for the range of conditions within a mechanical sealing system, and is widely used.

In the same way a pencil transfers graphite to a piece of paper, mechanical carbon can transfer material to the mating face—the level of that transfer is where the technology comes into play.

Manufacturers of carbon-based materials for mechanical seal faces achieve specific tribology through formulation of different elemental forms of the carbon atom and the use of other proprietary elements. Processing these recipes results in a structure that is literally held together by atomic carbon bonds.

A mechanical seal’s mating pair is the heart of the system and the two components are designed to work together. There exist optimum pairs for specific conditions.

The components of the recipe enable the proper tribology—too much or too little film transfer would result in shortened life or performance of the mechanical seal.

Carbon is also a critical component in some of the hard face materials used in mechanical seals because it combines with metals at high temperatures to form metallic carbides. These materials include tungsten carbide and silicon carbide.

These carbides provide superior hardness and stiffness. They are not self-lubricating and therefore cannot run “dry,” but they run well against mechanical carbons.

GRAPHITAR carbon is an ideal material for use as a sliding face within a mechanical seal configuration, operating successfully against counterfaces in materials such as Silicon Carbide , Tungsten Carbide and other ceramics. GRAPHITAR is a very hard material and extremely resistant to wear. It is lubricated by most fluids so that the medium being sealed can serve as the seal lubricant. GRAPHITAR’s permeability can be controlled to allow the lubricating medium to be metered to the sealing surface or to be impervious and fully “Leak Tight” to 6 BAR pressure of nitrogen.

Seal faces can be manufactured as fully machined components, lapped to 3 light bands, as semi finished parts or as finished parts pressed to size parts.

Our NUTECH cartridge mechanical seals are designed to fit all ANSI pumps for ease of installation and are pressure tested at our Texas manufacturing facility prior to shipping.
