One of the simplest seals is packing, or compressing some sort of flexible material into a space to control the flow of a fluid. Packing probably dates to at least the time when humans began ...

However, there are several disadvantages that the mechanical seal addressed. Friction caused by the shaft rotating against the packing leads to wear over time, resulting in increased leakage until ...

Circulating pumps at the coal-fired facility were to be converted to mechanical seals from traditional packing to prevent wear on pump shafts and better control leakage (Figure 5). Over time ...

Pumps solutions provider Mechanical Rotating Solutions (MRS) contributed to a Limpopo-based platinum mine’s water-saving initiative towards the end of 2019 by replacing the existing pump gland packing ...
