What are the advantages of a mechanical seal

A mechanical seal is simply a method of containing fluid in a vessel (usually a pump, mixer, etc.) in which a rotating shaft passes through a fixed housing, or occasionally, the housing rotates around the shaft.

The challenge when sealing a centrifugal pump is to allow the rotating shaft to enter the "wet" area of the pump without allowing a significant amount of pressurized fluid to escape.

To meet this challenge, a seal is required between the shaft and the pump casing that can contain the pressure of the pumped process and withstand the friction caused by the shaft rotation.

1) The irreplaceable benefits of using seals

Why do we use mechanical seals?

No "visible" leakage - The seal does not leak steam when the fluid film on the seal face reaches the atmospheric side of the seal face. If it were collected and condensed, this would be equivalent to about 1/2 teaspoon per day at normal operating pressures and temperatures.

The modern cartridge seal design will not damage the pump shaft or sleeve.

Seals have built-in springs that reduce routine maintenance so that the seal can automatically adjust as the working surface wears.

The lighter surface of the seal consumes less power than a packed seal.

Bearing contamination is reduced in normal operation because the lubricant is not affected by seal leakage and flushing.

Corrosion of plant equipment is also reduced if the product is included in the pump.

The vacuum can also be sealed with a technology like mechanical seals, which is a packaging problem caused by air being drawn into the pump.

The reduction in wasted product from mechanical seals will save money, even though water is an expensive commodity that requires less cleaning of the area.

2) The benefits of mechanical seals for your pumps

Mechanical seals are the preferred sealing method for most pump manufacturers because they are suitable for a wide range of applications. They offer 5 major advantages over traditional stuffing boxes

Reduced friction and power loss: The surface of the mechanical seal maintains a fluid film lubrication. The combination of the ideal spacing between the two surfaces reduces friction, which means you can reduce power.

Zero product leakage: The main purpose of a mechanical seal is to prevent leakage of pumped fluid. Although mistakes can sometimes be made, this can be prevented by proper installation and venting.

Eliminate excessive wear: Properly installed mechanical seals can help protect your equipment. There are clear guidelines in place for alignment, impeller positioning, etc. These guidelines provide stability and extend the life of your equipment.

Reduce maintenance: When properly aligned, free of vibration and at the right temperature, mechanical seals are very durable and easy to repair when problems arise. The cost of fixing mechanical seals is also relatively low.

Long-term cost benefits: Less fluid is lost in leaks, which means less waste from using mechanical seals, fewer pump failures and easier maintenance, resulting in significant savings. Mechanical seals also reduce hazards to pump operators and bring associated health, safety and environmental benefits.
