In the present day world, mechanical seals are the most ideal
accessories on all your fluid pumps and are the most feasible substitute to the
lip seals and packed glands. A mechanical seal helps to prevent leakage,
control pressure and prevent contamination in plumbing setups, especially your
pumps, by joining the mechanisms together. How good a mechanical seal is,
depends on the capacity of adhesion for sealants and the compression power in
case of gaskets. Mechanical seals come in various forms and nomenclatures.
Single Spring
Mechanical Seals
These seals are the basic kind of seals for the rotating face
of your pump. They can solve most of your sealing requirements and can
withstand shaft velocities up to 3600 rpm and high temperatures up to 500
degrees Fahrenheit.
Single and Double
Cartridge Seals
The Single and Double Cartridge Seals come in complete sets
that include seal faces, set screws, o – rings, gaskets, flush ports and a
gland. These seals provide additional safety for your pump if it is already
troubling you.
Metal Bellows Seals
Metal Bellows Seals can tolerate very high temperatures going
up to 800 degrees Fahrenheit. Packings are provided with Static Grafoil and not
with heat sensitive o – rings. Each and every part of these mechanical
seals is specially designed to adjust to such high temperatures without
any hassles. The seals allow a lot of pressure as they are hydraulically
balanced. They come with the added advantage of self cleaning by using the
centrifugal force.
Multi – Spring Seals
This seal makes use of the latest technology and uses a
static o – ring, which provides it with extra durability. They work quite
effectively in almost all types of rotating shaft equipments. A set screw provided
with the seal makes sure of a connection between the shaft and the seal. The
seals come in highly durable stainless steel bodies.
Split Cartridge Seals
The Split Cartridge Seals for pumps facilitate the
installation of a new seal into a vertical or a large – sized pump.
Mixer Seals for Pumps
These seals work within a range of -40 degrees F to 550
degrees F, depending on the selection of the elastomer. The seal allows easy
installation mechanism with isolated springs to prevent clogging.
Advantages of Mechanical Seals
The mechanical seals come with the unique features of a
greater longevity, much lesser power loss and friction, minimized wearing of
the shafts and sleeves, sufficient flexibility for accommodating shaft
deflections and no hassles of maintenance whatsoever.
