Ashish Seals is one of the leading manufacturers, suppliers, and exporters of Dry Running Mechanical Seal, based in Mumbai. As a trusted ISO 9001-2015 certified company, the seals make use of some chemicals and works so that it does not contaminate the process. The seal consists of the rotating ring as well as the stationary ring and is non-contacting. It finds its application in food & pharmaceutical products, general light chemicals. We are the reliable Dry Running Mechanical Seal manufacturer and known to offers seals that are high quality. Also, it is widely demanded in various industries such as petrochemicals, painting and printing, oil refining, paper making, electricity generation, chemical engineering, pharmacy, machinery manufacturing, many others that will require seals and pumps.

Working Principle

The seal is simple and rugged designed that can tolerate shaft movement, deflection, and vibration. It eliminates the necessity of auxiliary equipment for lubrication and cooling that is needed for a mixer. As there’s not any usage of barrier fluid, it removes the chances of product contamination and can be used in high vacuum applications. As there’s no need for any external lubrication for the seal faces, it is termed as dry running seals. Here, many springs are externally mounted and a reverse balanced seal having an O-ring is present that acts as a secondary sealer. It is available with cartridge, non-cartridge & bearing assembly.

The seal is capable of forming a direct contact seal that for an extended time at both high and low rotational speeds without wear of the seal faces or undue heating. The stator face’s rear surface and the mounting plate’s corresponding surface are lapped for max contact of direct heat transfer. Simultaneously, air from the surrounding region of the shaft is circulated via the cooling annulus directly behind the stator face and out via exit ports.

Factors to Consider Before Choosing Dry Running Mechanical Seal

There are several factors that one needs to consider when it comes to choose Dry Running Mechanical Seal from authentic Suppliers/exporters. These include the kind of liquid to be handled, pressure of the seal chamber & seal size, know the viscosity of the liquid, etc.
