For solid particle medium pump Mechanical seal for kettle

With the development of modern industry, especially oil and gas field development, mine exploitation, metallurgy, power, paper making, fine chemical industry, salt chemical industry, water supply and drainage, sewage treatment, food processing and other industries, there are more and more pumps conveying media containing solid particles. The fluid medium contains solid particles and fibers, which is very unfavorable to the work of the pump mechanical seal. When the solid particles in the fluid medium enter the seal secondary end face, the wear and leakage of the seal face will be aggravated. The solid particles deposited around the seal will also interfere with the function of the seal, making the seal invalid. Similarly, fiber materials entering the sealing secondary end face will also cause serious seal leakage.
