During maintenance, the construction period was significantly extended due to an assembly error in the set position dimensions.

A sudden leak has occurred and an alternative mechanical seal is needed immediately.

I want to eliminate gland packing leaks and improve safety in the factory.

CM3 Seal Type Selection Table
*1 For fluids that are prone to crystallization, such as alkalis and salts, please use water quenching to prevent adhesion (poor tracking) due to leaking liquid.
*2 Slurry concentration is a reference value based on actual results. Depending on the slurry properties, edge seal + diaphragm may be selected.

Introduction example
Example of introduction to chemical conversion liquid (zinc phosphate) pump

Zinc phosphate reacts with the iron in the liquid, turning into iron phosphate and crystallizing it. Iron phosphate has strong adhesive properties and can adhere to a variety of surfaces.
This resulted in a large amount of deposits adhering to the part, as shown in the photo on the left, causing it to malfunction.

As a countermeasure, a diaphragm type Cartridge Mechanical Seal is adopted.

By applying the diaphragm type, the seal life is 1 to 1.5 months.
This has improved dramatically to 1.5 years.

Installation example of concentrated sludge pump

The slurry contained in the thickened sludge contains various particles. As a result, the slurry entered the driven packing as shown in the left photo, causing malfunction.
*Disassembly of the diaphragm type immediately after removal from the concentrated sludge pump.
The diaphragm keeps out contaminants such as staples and gravel.
