Specification of Packungen Packings Merkel

Gland packing is usually made with a braid or woven system with a box cross section and the constituent materials can be graphite, acrylic, PTFE, asbestos and so on the liquid at the pump that functions as a lubricating gasket.

A seal which is generally also called a seal is a part in a machine tool construction that functions as a barrier / blocker in and out of liquid, both process fluid and lubricant. Seal refers more to the understanding of a function regardless of its form and material, if it functions to prevent leakage.

The selection of the best seal is very important for the successful use of the pump to get pump reliability. In general there are two kinds of seals, the first is a static seal used at a meeting between the two surfaces to be sealed without movement. Gaskets and a-rings are common examples of static a-ring seals originally referring to a round rubber that functions as a seal. There are a-ring materials made from natural rubber, EPDM, Buna, Neoprene, Viton, Chemraz, Kalrez, Isolast to Encapsulated a-Ring type, where the a-ring is wrapped with PTFE. Some are purely made from PTFE and are called Wedge. A common example of using sealing devices is a rotating shaft seal at a pump. To find out more about the function of this insulator, we must first know the basics of pump knowledge. In a centrifugal pump, liquid enters the pump through the suction section at the center of the rotating impeller. When the impeller fan is spinning, they deliver movement to insert the product and then leave the impeller, collected in the pump housing (casing) and leaving the pump through pressure on the pump's discharge side. Discharge pressure will push some products down behind the impeller toward the shaft, where it will try to escape along the rotating shaft. Pump manufacturers use a variety of techniques to reduce the pressure of products trying to come out.
