How the Mechanical Seal Works on the Pump - China Sealcon

A pump moves liquid or gas using mechanical action and must be sealed to operate efficiently without leaks. Previously, pump seals were often rings, which were less effective at preventing leaks. Nowadays, mechanical seals are mostly employed in pumps due to their superior performance in leakage prevention.

The primary issue mechanical seals address is leakage. Their most notable advantage is enabling the pump to function without leaks. Here are some benefits of mechanical pump seals:

Advantages of Mechanical Pump Seals

Mechanical seals significantly reduce fluid loss within the machine, which means lower maintenance costs and enhanced operator safety. Less leakage translates to fewer slip hazards and fewer chances of toxic emissions if the pump handles hazardous chemicals.

While some leakage is to be expected, it's often minimal. Under standard operating conditions, experts suggest that a small, "healthy" leak rate — about half a teaspoon per day — is manageable and often recaptured by the system.

Mechanical seals are equipped with built-in springs that adapt to varying wear surfaces, reducing the need for frequent maintenance and ensuring optimal operation.

How Mechanical Seals Work

Mechanical seals create an impermeable barrier between the fixed part of the rotating equipment and the shaft, commonly used in pumps. Maintaining the water tightness of the pump is critical. This tight seal is achieved by a thin fluid film between two friction surfaces, which not only prevents fluid passage but also acts as a lubricant, reducing wear. With a mechanical seal, pumps can operate efficiently without leaks.
