Mechanical seal M74

Shaft Seal M74

Years ago, most pump shafts were sealed using rings of soft packing, compressed by the packing gland, but this type of shaft seal required a fair amount of leakage just to lubricate the packing and keep it cooling. Then came the development of the mechanical seal, which accomplishes the job of restraining product leakage around the pump shaft with two very smooth surfaces (the stationary and the rotating). Even though these mechanical seal faces also require some leakage across its faces, this leakage normally evaporates and is not noticeable.

However, because of the delicate components used for this new sealing method, mechanical seal failures are the greatest cause of pump down time. To avoid this, it’s essential to apply the right seal for the desired and appropriate function.

A Mechanical seal can be exposed to a wide variety of operating conditions—sometimes very different from conditions the seal was intended for—which can cause issues down the line. However, even if your seal is the right one for the job, there can be times when it fails faster than anticipated.

When this happens, it’s imperative that you act quickly to identify the cause of leakage. Every minute of downtime results in lost production and maintenance fees

The Mechanical seal model  M74D can Replace BURGMANN M74D,which is widely used for industrial pumps.  
The normal material combination include SIC/RESIN CARBON/NBR/SS304,sic/sic/nbr/ss304,tc/tc/nbr/ss316 and so on.
we also can make changes as customers’requirement or totally design a new type of mechanical seal to meet clients’needs.
