Mechanical seal barrier fluids are engineered to cool and lubricate mechanical seal faces in both unpressurized and pressurized systems. They ensure safe and lasting equipment performance and help increase the lifespan of mechanical seals. The versatile formulas of these fluids demonstrate that they can be used in a variety of applications.
Barrier fluids are created while focusing on the safety of the environment and equipment operators. All types are chemically inert, non-toxic, non-flammable, and compatible with several elastomers, plastics, and metals. A one-size-fits-all approach can’t be used when selecting mechanical seal barrier fluids.
Why You Need a Mechanical Seal Barrier Fluid
Choosing the type of mechanical seal barrier fluid depends on the system’s sealing arrangement. The fluid is used in an application that’s equipped with pressurized dual seals, and the system can pressurize the fluid being used. As the fluid gets pressurized, it creates a barrier between the pumped fluid and the atmosphere and continues to circulate to protect the integrity of the mechanical seal.
High and Low-Velocity Barrier Fluids
The hazardous processes of natural gas, petroleum, and chemical production use rotary and centrifugal pumps at increased rotational velocities. For reliable and safe operations, barrier fluids at low viscosities are formulated to prevent blisters in carbon seal faces and allow good heat dissipation.
On the other hand, low-velocity barrier fluids can seal rotational equipment that has direct contact with sensitive chemical processes. Rotary agitators and mixers are equipped with dual and tandem sealing solutions that operate at low velocities and high temperatures. The goal of the barrier fluid under these conditions is to reduce or prevent the process fluids from leaking.
Factors to Consider When Looking for a Mechanical Seal Barrier Fluid
The primary factor to consider when choosing a barrier fluid for mechanical seals is safety. Whether stored or in use, the fluid you select should comply with high safety standards. The fluid chosen must be compatible with all seal materials, non-flammable, and chemically inert. Moreover, it should offer good lubricity, low compressibility, and good heat transfer.
