THE DIFFERENCE BETWEEN CARTRIDGE AND NON
CARTRIDGE MECHANICAL SEAL

• What should be considered while choosing
  a mechanical seal type?
• There are several aspects- the cost of
  installation, characteristics of the pump,
  long-term running cost, and the anticipated cost
  of operation.
• As far as seal types are concerned, there are two
  types of seals- cartridge type and non-cartridge
  type.

THIS BLOG EXPLAINS TO YOU THEIR DIFFERENCE,
BENEFITS, AND DISADVANTAGES.
CARTRIDGE MECHANICAL SEAL NON-CARTRIDGE MECHANICAL SEAL
A cartridge seal is typically an enclosed type of seal system that has preassembled components. In a pre-assembly, you have a gland, sleeve, and other hardware components. This seal system is easy to install. You do not need a specialist or technically skilled person for that. Non-cartridge seal has two separate stationary and dynamic parts. Here, component seals are not preassembled. You need skilled technicians to install it.

CARTRIDGE MECHANICAL SEAL

• Since the seal is pre-assembled with fix axial
  settings, there are no measuring errors.
• The functional security is also high. Experts
  praise it for less possibility of axial
  displacement.
• There are hardly any performance issues in a
  cartridge seal.
• The design prevents the entry of dirt inside the
  seal faces.  Hence, you need not worry about seal
  damage due to dirt.

• Reduced installation time results in reduced
  installation cost and reduced downtime for
  maintenance.
• The repair time of the cartridge seal is also
  less.
• Customer shaft and shaft sleeve are
  well-protected. You do not need custom-made shaft
  to operate it because there is an internal shaft
  sleeve.
• The disadvantages of a cartridge seal are high
  initial cost and additional space requirement.

NON-CARTRIDGE MECHANICAL SEAL

• If the installation of any of the components,
  i.e., seal face, O-ring, or seal axial setting on
  the shaft is there, then the seal life reduces.
• Even it causes an immediate seal failure
  sometimes.
• Still, these seals have several benefits.
• Non-cartridge-type mechanical seals are less
  expensive.
• Hence, the initial cost of purchase is less.
  Since there are individual parts, you can stock
  them independently and not the entire seal. It
  results in reduced spare part cost.

• It is adaptable to small pumps easily.
• As far as disadvantages are concerned, the
  non-cartridge seal is more susceptible to damage.
  The entire seal is not encased within secure
  housings here.
• There are exposed parts that can get damaged
  easily during installation or transportation.
• Also, non-cartridge type seals need precise
  measurement while installation. Else, there is a
  risk of seal failure.
• Installation of a non-cartridge seal is
  time-consuming. It needs more operator time.
