A mechanical seal is a sealing device used in rotating equipment such as pumps, mixers, reactors and compressors to prevent leakage between a rotating shaft and a stationary housing.

Mechanical seals are used in pumps, reactors, agitators, mixers, blenders, dryers, vessels, compressors and other rotating equipment where leakage control is important.

Ashish Seals offers pump mechanical seals, cartridge seals, agitator seals, reactor seals, rubber bellow seals, metal bellow seals, single seals, double seals and application-specific mechanical seals.

A cartridge mechanical seal is a pre-assembled sealing unit that includes seal faces, gland, sleeve and other components. It helps reduce installation errors and improves maintenance convenience.

A single mechanical seal uses one sealing interface, while a double mechanical seal uses two sealing interfaces with a barrier or buffer fluid system for higher safety, hazardous media or critical applications.

A double mechanical seal should be used when handling hazardous, toxic, costly, high-temperature, crystallising, abrasive or leakage-sensitive fluids where extra sealing safety is required.

A pump mechanical seal is used to prevent liquid leakage from the pump shaft area while allowing the shaft to rotate during operation.

An agitator mechanical seal is used in mixing and reactor equipment to seal rotating shafts operating under pressure, vacuum, temperature or chemical exposure.

A reactor mechanical seal is designed for reactors used in chemical, pharmaceutical, food, polymer and process industries where sealing performance is critical under pressure, vacuum or corrosive media.

To select the right mechanical seal, consider media, temperature, pressure, shaft size, RPM, equipment type, direction of rotation, operating cycle, solids content, corrosion level and safety requirement.

Common causes of mechanical seal failure include dry running, wrong material selection, misalignment, high vibration, incorrect installation, poor lubrication, excessive pressure, thermal shock and contaminated media.

Yes, Ashish Seals can help review the application and failure condition to suggest better seal design, material selection, installation correction or operating improvements.

Mechanical seals may use carbon, silicon carbide, tungsten carbide, ceramic, stainless steel, elastomers, PTFE, Viton, EPDM, graphite and other materials depending on the application.

Yes, mechanical seals can be designed for corrosive chemicals by selecting compatible seal faces, elastomers, metallic parts and suitable seal arrangement.

Yes, Ashish Seals can manufacture mechanical seals based on sample, drawing, equipment details or application data.

A rotary joint is a device used to transfer fluid or gas from a stationary source to rotating equipment without leakage.

A rotary union is a rotary sealing device that allows media such as steam, water, air, oil or hot oil to pass into rotating machinery.

Rotary joint and rotary union are often used for similar functions. Both transfer media between stationary and rotating parts, but design selection depends on media, pressure, temperature, speed and application.

Rotary joints are used in paper machines, printing machines, textile machines, rubber processing, steel plants, chemical equipment, food processing equipment and industrial dryers.

Rotary joints can handle steam, water, hot oil, hydraulic oil, air, coolant and other industrial media depending on design and material compatibility.

Choose the right rotary joint based on media, pressure, temperature, RPM, flow rate, connection size, mounting style, direction of rotation and operating environment.

Yes, rotary unions can be designed for high-temperature media such as steam, hot water and hot oil, depending on seal design and material selection.

Rotary joint leakage can occur due to worn sealing faces, wrong installation, poor alignment, high vibration, unsuitable media, excessive pressure or temperature beyond design limits.

Yes, Ashish Seals offers rotary joints and rotary unions suitable for steam, water, hot oil and other industrial media applications.

Yes, rotary joints can be customised according to media, size, connection type, speed, operating pressure, temperature and equipment requirement.

A thermosyphon pot system is a seal support system used with double mechanical seals to provide barrier or buffer fluid circulation and maintain a controlled seal environment.

A thermosyphon pot is used to improve seal cooling, lubrication, pressure control and safety in double mechanical seal applications.

Thermosyphon pot systems are used in chemical plants, refineries, pharmaceutical plants, reactors, agitators, mixers, pumps and critical process equipment.

To select a thermosyphon pot system, share seal type, equipment type, operating pressure, temperature, media, barrier fluid, cooling requirement and plant safety requirement.

Yes, Ashish Seals can supply thermosyphon pot systems along with compatible mechanical seals for double seal applications.

Mechanical seals are required in pumps, reactors, agitators, mixers, blenders, dryers, vessels, compressors and rotating equipment where leakage prevention is required.

Yes, Ashish Seals products are suitable for chemical processing plants handling corrosive, high-temperature, hazardous and process-sensitive fluids.

Yes, mechanical seals are used in pharmaceutical reactors, mixers, pumps and process equipment where hygiene, purity and leakage control are important.
