TYPES OF MECHANICAL SEALS
TO FIT YOUR APPLICATION
Mechanical seals are sealing solutions for any machine that has a rotating shaft, like pumps or compressors. Mechanical seals are a kind of packing that is installed on the power transmitting shaft of a rotating machine. Without a seal or with just gland packing, the liquid will leak and the axis will wear. With a mechanical seal, leaks are minimized and the axis does not wear. This is because the separate rings of the mechanical seal allow for a precise and custom design to fit around the axis but not affect the rotating force of the shaft. Mechanical seals prevent leaking even with hazardous substances or under high pressure or high rotating speed.
Most mechanical seals are composed of two rings, a rotary ring installed on the shaft and a stationary ring installed on the pump housing. The rotary ring rotates with the shaft, and the two rings rub against each other, ensuring clearance of micrometers between them.
