The working principle of mechanical seal for pump is to form the thin liquid film between rotating ring and shaft, so that it can efficiently prevent leakage of medium and make the end face lubricated, which help achieve the sealing effect. Mechanical seals are often used in rotating machinery, such as pumps, compressors, and reaction stirred kettle.

There are 2 common sealing methods of the pump: mechanical seal and soft packing seal. Each of them has different characteristics and they are also suitable for different occasions. The correct selection of mechanical seals is beneficial to reducing the cost and improving the working efficiency.

1. Good sealing function. In the long working, the sealing state of mechanical seals for pump is very stable, and the leakage is small: about 1% of the leakage of soft packing seal;

2. Long service life. The general service life can reach more than 1~2 year when used in oil and water working occasions; and the mechanical seals should have 6-months service life when used in chemical medium;

3. Small consumption of friction power. The friction power of mechanical seals for pump is only 10% ~ 50% of the soft packing seal. And the abrasion of the shaft or sleeve can be negligible;

4. Long maintenance period. The mechanical seals for pump can still meet the requirements of usage, even thought its end face is in a certain range of repair;

Mechanical seals for pump have complex structure, higher requirements and cost. And the operators needs to have a certain level of technology, such as the basic knowledge of fitter and the characteristics of the mechanical seal.

These seals are manufactured by full automated assembling lines at our global production sites, and has high market share in worldwide specifically in the category of seals for automotive water pumps. These seals are also suitable for industrial pumps. Because mechanical seal failures are the number one cause of pump downtime, uses only top of the line materials when it comes to manufacturing this critical seals. most pump shafts were sealed using rings of soft packing, compressed by a packing gland, but this type of shaft seal required a fair amount of leakage just to lubricate the packing and keep it cool.

“The mechanical seal represents the heart of the water pump. Each stage of production must be carefully controlled and managed – down to the finest detail – starting from the choice of raw materials.

It’s work we have scrupulously improved and developed every day for more than 18 years to guarantee our clients high performing and reliable products, produced in the shortest time possible, always focusing on reducing environmental impact.

Mechanical seals are indispensable for sealing rotating shafts. They make sure that the fluid handled remains in the system, prevent emissions and thus protect the environment from contamination. High-quality shaft seals in the form of mechanical seals also ensure maximum economic efficiency and operating reliability for pumps. This is crucial because the majority of repairs arise due to sealing problems.

And this is where KSB’s mechanical seals can make a difference: as well as impressing with a robust design, they offer straightforward installation and optimal integration in the seal chamber – ensuring reliable and efficient system operation.

We recognize and understand the vital role of water pump mechanical seals in their application. With purposes including securely fastening components within systems, and contaminants prevention such as gases and liquids from navigating through enclosed and sealed areas. That is why we offer wholesale water pump mechanical seals in different variations and diversities to ensure the integrity and efficiency of systems they will be applied to will function successfully and optimally. The different seals" types available include static that does not move along with other seals and dynamic seals that move collaboratively.

Depending on the industry and selected purpose, we consider water pump mechanical seals requirements. Requirements are like pressure, that is pressure changes, to ensure they can withstand and do not deform by the sealed fluid, the load and how it can withstand deflection, dynamics such as the alignment and vibration, and temperature covering the environmental conditions and the heating arising from the friction of the seal operation and fluid movement.

The seals are either bolts, nuts, or washers. Seal bots are commonly used because of their benefits in being reusable, preventing fluids and contaminants from escaping even under high pressure. Nuts are essential on temperature withstanding and compatibility with screws, studs, and bolts, in addition to, easy installation. Moreover, washers can withstand high pressures and are compatible with other seals.
