How to Choose Mechanical Seals?
If mechanical seals have been appropriately chosen for the application, they can function for many years without experiencing any problems. Especially for industrial use, you need to make sure that you are carefully making the right decision.
You must consider various factors to choose the right type of seal and construction materials, such as pneumatic seals. It is necessary to understand the application data (or operating circumstances). In the following sections, we define the working events and discuss the material properties to consider when choosing a suitable material.
Keep reading this blog to learn the factors you must consider while choosing a mechanical seal.
The first stage in the seal selection procedure is determining the precise liquid being handled. The fluid being processed must be able to tolerate the seal material. Chemical compatibility between the seal components and the fluid is essential to prevent seal failure.
- Pressure
You need to make sure that you are considering the pressure of the circumstances. Determine it by the pressure in the seal chamber and the seal size.
- Temperature
A suitable seal material must be chosen to accommodate the temperature of the liquid. Temperature is crucial since certain seal materials are rated for specific temperatures, and you should stay within these ranges.
- Liquid Characteristics
To ensure optimum seal life, it is crucial to understand the liquid’s viscosity. Abrasive liquids can cause excessive wear and reduce the seal’s lifespan. Operators have the choice to use mechanical seals on these challenging fluids through the use of double seals or an external flush plan.
- Reliability and Emission Concerns
Regarding reliability and emission problems for an application, each company has its own requirements and operating methods. The chosen seal type and configuration must adhere to the pump application’s specified dependability and emission regulations. Double seals are becoming more and more popular as the go-to solution in manufacturing firms as environmental safety becomes a big subject.
You can choose the material for the seal’s overall construction as well as its face and component materials after you are aware of the specific working conditions. Be sure to take into account the following material characteristics while choosing the seal’s construction material:
- Temperatures restrictions
- Property resistance to chemicals
- Flexibility
- Resistance to wear
- The qualities of conductivity and thermal expansion
Additionally, bear the following material properties in mind when choosing the seal’s face and other component materials:
- Resistance to wear
- Low friction and leakage characteristics
- High thermal efficiency
- resistant to corrosion
The Bottom Line
Keep in mind that a mechanical seal suggestion is complete with a seal support plan, such as a seal flush piping plan, while you engage with your local seal supplier. Additionally, you can get in touch with BMG to learn more about it.
