Lepu Seal mainly provides two types of bellow seal which include high-precision metal bellows seal and PTFE bellows.
Metal bellow is the perfect seal choice for extreme temperature ranges. Processed by automatic CNC technology, it can keep high precision for a long period and can be used as a 100% replacement for Eagleburgmann MFL85N. The bellow is a kind of elastic vessel that can be compressed when pressure is applied to the outside of the vessel, and back to the original shape when pressure released. As for our PTFE bellow, we select 100% original Teflon (PTFE) raw material for manufacturing the bellow. It is mounted externally, providing much more convenience for people. Being designed with spring protective sleeve, it provides maximized protection for the product. Made of strong-quality stainless steel, the seal frame is anti-corrosion and features high impact resistance. Under extreme application, the product can still run perfectly such as high concentrations of acids, salts, strong oxidiozing, reducing agents, and chemically active organic compounds commonly used on PTFE filled pumps. When being used on the pumps, the product has the function of physiological inertia, sterilization and disinfection. What's more, the product has small friction resistance, no adhesion and will not cause creeping effect. The elastic inner core has good elasticity, which greatly improves the sealing effect of PTFE mechanical seal.
