Product Introduction
LPDO Floating Seal Design Feature:
The high alloy cast iron floating seal for mining machines is designed to provide superior durability and performance in tough mining conditions.
Duo Cone floating seals used in heavy machinery and equipment to prevent the leakage of lubricants and fluids. normally a duo cone seal include two identical metal seal rings and two elastomer o-rings. The metal seal rings of LEPU Duo Cone Seals are made of high-alloy cast iron, with precision-machined face, provide strong sealing ability and high resistance when running.
LEPU 's floating seal designed to replace famous international brand, so high quality with reasonable price is our strong advantage.
● Srong ability for wearing and corrosion resistant, long service life, free maintenance.
●Excellent sealing capability against external contamination such as abrasive media, moisture, chemicals, oil and grease.
●Self-centering to compensate for shaft eccentricity or misalignment.
●Adopting oil lubrication and cooling technology, it is more suitable for high-speed equipment.
Unique Innovation Design for LEPU floating seal
● Unique sealing face design reduces rust, improves O-ring grip and eliminates O-ring slippage.
● The cross groove design on the professional floating seal contact belt can ensure efficient oil flow and heat management, ensuring that the seal can operate under the most severe working conditions. At the same time, it can avoid many problems that rubber oil seals cannot solve.
● The end grinding surfaces of all products are made using an original process to ensure the consistency of the spherical angles of products in the same batch, avoiding premature seal failure due to angle mismatch.
● The O-rings we design and produce to match our floating oil seals have high elasticity, which can increase and prevent wear, making the product highly wear-resistant.
How deos a floating seal working?
Floating seals are consiste of two identical metal friction rings mounted one on top of the other and centred in their groove by two rubber components.
The two metal sealing rings interact with each other to form a contact sealing surface perpendicular to the axis. Since the O-ring transmits pressure from the housing to the sealing ring, one metal sealing ring rotates with the housing while the other remains stable. Therefore, the two mechanical face seals are in relative motion.
The two relatively moving face seals form an oil film on the surface of the contact band. This oil film is the key to sealing. During rotation, the mating surfaces form a contact band with a width of about 0.2 mm (0.008 inches) to 0.5 mm (0.02 inches) to keep the oil lubricated and resist foreign matter. When wear occurs, the contact band will move inward. However, the O-ring releases elastic compensation to keep the mechanical face seal in a precise position to maintain its stability.
