This mechanical seal is specially designed for flue gas desulfurization (FGD) circulation pumps operating under highly corrosive and high-solid-content conditions. It adopts a single or double cartridge seal structure combined with a balanced design, effectively improving sealing stability and service life. With a compact structure and easy installation, the seal ensures reliable long-term performance in demanding environments, and is widely used in power plants, chemical industries, and environmental protection systems.
