How Do Mechanical Seals Work in Pump Applications?
Time to Read: 0m 0s
A mechanical seal is a device used in pump systems that reduces fluid leaks and prevents contamination in the housing. They are designed to keep fluid contained and minimize downtime associated with maintaining the pump system while enhancing overall efficiency and performance to keep your system operating as intended over long periods. At Springer Parts, we supply a range of replacement mechanical seals, seal components, and device upgrades for top pump brand manufacturers to meet your needs for pump applications across various industries.
What is a Mechanical Seal?
Mechanical seals are devices that prevent fluid leakage from rotating equipment by creating a seal between the rotating and stationary parts. Utilizing three sealing points, which include the rotating face, the stationary face, and the interface, mechanical seals contain the fluid within the pump housing and prevent particles from entering the housing to maintain the integrity of industrial processes. With mechanical seals, pumps achieve efficient operation by minimizing leakage and reducing friction, while offering decreased wear and tear, fewer unexpected breakdowns, and a longer lifespan.Primary Components of Mechanical Seal Parts
Made of the primary sealing ring, stationary face, interface, and secondary seals, mechanical seal components feature moving and stationary parts to maintain pump performance. These components interact for high-quality, leak-free pump operation by:- Primary Sealing Ring: Also known as the rotary face, this portion is mounted to the shaft and rotates with it to provide one half of the sealing interface.
- Stationary Face: The fixed-in-place mate to the primary sealing ring, this component assists in creating the tight seal for pump operation.
- Interface: Where the primary sealing ring and stationary face meet, the interface offers fluid film lubrication to reduce friction and wear between the faces.
- Secondary Seals: Components, such as O-rings and gaskets, are used as secondary seals for security between parts that prevent leakage around the shaft.
How Does a Mechanical Seal Work?
Mechanical seals are situated where the pump’s rotating shaft passes through the housing, featuring a rotating and a stationary face held together by a spring and secondary seals to produce a leak-tight barrier. These essential components are compatible with the pump’s fluid pressure and system design to maintain the seal for reliable operation. They are designed to prevent leaks while allowing for continuous movement of the shaft, meaning that over time, they will wear down, which can lead to pump failure. Maintaining and replacing these components is key to pump performance, longevity, and reliability.Common Pump Applications for Mechanical Seals
Ensuring reliability and performance for various applications, mechanical seals are crucial components in pump equipment. They are often used for operations, such as:- Centrifugal pumps
- Lift stations and wastewater treatment
- Chemical processing systems
- Other industrial applications
