Dry Seals
There are many applications that work with powdered or extremely viscous products which have no lubricant properties to permit the mechanical seal contact surfaces to function without immediately becoming worn. Finding a sealing element that guarantees sealing without leaks and adds durability to applications of this type poses a difficult challenge. Braided packing is often used, which gives rise to the disadvantages of this kind of element, such as inevitable leakage to a greater or lesser extent, the use of elements prone to wear such as sleeves to protect the shaft, frequent maintenance to replace the sleeves and change…
