A mechanical seal is designed to seal the gap between a rotating shaft and a stationary housing, or occasionally, where the housing rotates around the shaft, preventing fluid leakage within a vessel such as pumps, mixers, etc., ensuring efficient and reliable operation of the equipment.
Mechanical Seals provides various choices to fulfill different requirements, making it a great option for efficiently maintaining and repairing equipment.
Conical 'O'-Ring Mounted Mechanical Seals: These seals are available in both DIN and standard dimensions, offering reliable performance and preventing leakage, making them ideal for use in pumps, compressors, mixers, and agitators. Their conical shape allows easy installation and alignment. In demanding operational environments, these seals ensure durability and efficiency, contributing to equipment productivity.
Parallel 'O'-Ring Mounted Mechanical Seal: These seals are available in both imperial and metric sizes, provide reliable sealing performance in challenging environments, making them suitable for industries such as marine, paper, refrigeration, wastewater, and textiles. Their robust and flexible shape ensures high performance, leakage prevention, and system integrity.
Water Pump Mechanical Seals: Used in significant quantities for the production of pumps used in pools, showers, irrigation, and heating systems, these seals offer outstanding sealing performance designed specifically for water-related applications. Their cost-effectiveness and reliable sealing capabilities make them a popular option in diverse industries associated with water.
Elastomeric Bellows Mechanical Seals: With its non-clogging design, these seals are ideal for various applications and exhibit excellent performance when dealing with media that includes solid particles. They provide reliable sealing performance in diverse operating conditions.
Multiple Spring Mechanical Seals: Both balanced and unbalanced designs offer an optimal solution in corrosive environments. With a standard stainless-steel construction, these seals guarantee durability and resistance to corrosion, providing reliable sealing performance in challenging conditions, and making them well-suited for demanding industrial applications.
Diaphragm Mechanical Seals: These single spring seals with an elastomer membrane are tailored for demanding applications. Covering a range of sizes to fit standard shaft and housing dimensions, these seals ensure compatibility with various equipment. Offering reliable sealing performance in challenging operating conditions, is a durable choice with flexible sizing options for a wide range of industrial applications.
Wave Spring Mechanical Seals: The compact and bi-directional wave spring mechanical seals are the right choice for applications with limited space, such as rotating lobe pumps. Their hygienic properties are well-suited for pumps used in industries such as food, dairy, brewery, and pharmaceutical. They provide reliable sealing performance and are preferred for critical applications with industries demanding high cleanliness standards.
Cartridge Mechanical Seals: Designed with multiple springs and an O-Ring mounted cartridge, available with various bolt combinations and flush ports ensuring convenient installation and reliable sealing performance. The cartridge design not only simplifies maintenance but also facilitates quick and efficient replacements, minimising downtime.
Stationary Mechanical Seals: Designed to provide a reliable and stationary sealing solution between two stationary surfaces, such as pump casings or gearbox housings. These seals are used in various industrial applications ensuring efficiency, safety, and longevity in equipment across industries like manufacturing, oil and gas, chemical processing, and more. These seals are available in different designs and materials to meet specific requirements and operating conditions.
Safety: Provides a high level of safety by effectively preventing leaks and spills. Their ability to withstand high-pressure and high-temperature conditions ensures the containment of fluids within the equipment, minimising the chances of accidents, environmental harm, and equipment failures.
Reduced Downtime: Designed to last longer compared to traditional packing seals, which helps in reducing equipment downtime. With less need for maintenance and replacement can save businesses time and money in the long term.
Efficiency: Enhances the overall efficiency of the equipment’s operation by using less energy to overcome the resistance caused by friction, allowing equipment to operate at a higher capacity. This can result in increased productivity and lower operating costs.
Flexibility: Used in a wide range of applications, from pumps and compressors to mixers and agitators. Available in various materials, sizes, and designs to meet specific industry requirements, making them a versatile choice for numerous industrial applications.
Environmental Friendliness: As they reduce the impact of leaks and spills that can harm the environment & require less maintenance, which reduces the use of resources and waste production, makes them an environmentally friendly choice.
Fluid Type and Properties: The choice of mechanical seal depends on the fluid being transferred and its characteristics, including temperature, viscosity, and corrosiveness. To ensure compatibility with the fluid and prevent any potential leaks, it may be necessary to use different materials and designs.
Operating Conditions: Select a seal that can withstand the operating conditions of the equipment such as pressure, temperature, and speed, to which it will be exposed to. The right seal design and material must be chosen to ensure optimal performance.
Equipment Type and Design: Consider the design aspects, such as shaft diameter, housing, and mounting, to ensure seal compatibility.
Industry Standards and Regulations: Some industries have specific requirements for seals, such as food-grade materials for use in the food industry, or compliance with certain safety standards.
Cost: It is important to ensure the best value for your investment by considering the long-term costs, such as maintenance and replacement.
