Mechanical seals are used in centrifugal pumps and pumps that handle high-viscosity liquids. For example, in chemical plants, pulp and paper industries, purification plants, breweries, petrochemical and sugar industries, and so on.

Single Wave spring seals are designed for bi-directional flow. They can work with abrasive material, fuels and oils, water, highly viscous fluids, and low-aggressive chemical substances and liquids that contain solid particles.

To improve the design of mechanical seals, wave springs are used. The use of mechanical seals is to rotate the shaft against a stationary housing, e.g., a pump.

Multi-spring mechanical seals are unbalanced and single-acting. They are inside mounted, and they are independent of the direction of rotation. The face materials can be varied. Typically, they are ceramic, tungsten carbide, and carbon. The metal parts can be made of stainless steel and the secondary seal parts can be made of elastomers or PTFE.

The shaft diameters of the seals range from 12mm to 100mm and they can withstand the maximum pressure of 10 bar. The temperature ranges these seals can withstand are between -20 to 220 degrees Celsius. The rotation speed is typically 3000 rpm.

To get the optimum output, the seals are made from the best quality raw materials sourced from reliable sources.

Manufacturers ensure that the best quality control checks are performed at each stage of production. They make seals using stringent quality checks.

Multi-spring seals are widely used for various clean media applications. These seals find their major use in the procession of corrosive liquids. Due to its PTFE wedge construction of the secondary sealing member, the seal is applicable for various universal services.

The entire rotary part is designed using snap rings, which makes the installation and removal of the seal easy. As said before, seals are extensively used in aggressive chemicals like petroleum products and refrigerants.

Multi-spring mechanical seals are made as per standard specifications, but it is possible to manufacture bespoke seals based on user-specific parameters. The components in the cartridge offer the best reliability and efficiency. To provide uniform face cooling and reduce the heat on the faces, flushing ports are attached to them.

O-ring seal design helps to reduce scoring on the sleeve area as well as on the shaft. The devices ensure easy installation and less maintenance cost and longer service life.

Thus, a mult- spring mechanical seal is an important part of centrifugal and other pumps.
