When you want to keep large vo inside, then you
need specialized components. If you study
mechanical seals uses, then this is the most
prominent use of mechanical seal. Seals keep
fluid inside then the rotating shaft enters the
wet area of the pump. A mechanical seal is
considered very important because it can perform
this task effectively. Seal flawless performance

Mechanical seals are one of the important
mechanical components used in different types of
pumps and other devices.
Typically, there are two rings in the intimate
contact in a mechanical seal. One ring of them
remains stationary, and the other one rotates
with the shaft. Since there is no leakage of
fluid, you do not have any leaking fluid and
slippery floor.

Theoretically, a seal should not have any
leakage, but practically there is a small amount
of leakage that is acceptable. Also, you save a
good amount of money by using seals.
Before you make the decision to procure a
mechanical seal from a reliable company like
Leak-Pack, it is essential to know about its

Various components of mechanical seals
If you do market research, then you will get a
wide range of mechanical seals. By contacting an
e\pert mechanical seal manufacturer, you can pick
the seal suitable for your choice.

Typically, a mechanical seal contains
O-rings or wedges, V-rings, Secondary static
seals Static seal or stationary component Seal
for the rotating component to the shaft A spring
member, metal bellows, multiple spring or single
spring Other hardware like gland rings,
compression rings, collars, shaft sleeves

In a mechanical end face ring, the fundamental
components are seal ring, mating ring, secondary
sealing element, means of actuation, and means of
drive. Seal rings and mating rings are called
the primary sealing surfaces. In an engineered
mechanical seal, the seal faces are machined to
order. A long array of sizes and shapes of
mechanical seals and seal rings are available
from seal manufacturers. The main part of the
seal is the primary sealing surface. Hence, it is
called the heart of the mechanical seal.

The secondary sealing elements are PTFE Wedge,
rubber diaphragm, and O-rings. In a seal, the
sealing surface has a combination of hard as well
as soft material. It is generally made from hard
and soft materials. Some e\amples of hard
material are Silicon Carbide, Ceramic or Tungsten
Carbide. In a seal, there could be two
dissimilar materials (one hard and one soft) used
for the faces so that there is no adhesion of the
faces. For e\ample, there could be a combination
of Carbon-graphite and ceramic. These are popular
and preferred materials for making mechanical
seal faces.

In some operational conditions where you are
dealing with abrasive material, both surfaces are
hard.
The choice of soft material depends on
parameters, such as temperature, pressure, and
chemical properties of liquid. To achieve the
desired degree of flatness, a special process is
followed, which is called the lapping process.
The seals or rings are available in raw and
semi-finished conditions.
