Mechanical seal for solid particle medium pump:

With the development of modern industry, especially the development of oil and gas fields, mining, metallurgy, electric power, papermaking, fine chemicals, salt chemicals, water supply and drainage, sewage treatment, food processing and other industries, more and more pumps are used to transport solid particles. The fluid medium containing solid particles and fibers is very unfavorable to the operation of the mechanical seal of the pump. When the solid particles in the fluid medium enter the end face of the seal, the wear and leakage of the seal face will be aggravated. The solid particles deposited around the seal can also interfere with the function of the seal and cause the seal to fail. Similarly, fibrous substances entering the end face of the seal will also cause serious leakage of the seal.

Yizhou Pump Valve Technology has specially designed and developed different types and models of mechanical seals for this different industrial and mining needs, which can meet the application conditions of different industrial and mining forms.
