Primary Chemistry:
MSLV27 is a high-viscosity fluorinated barrier fluid engineered for higher-temperature, higher-face-velocity applications.
MSLV27 is a low-velocity mechanical seal barrier fluid formulated using Halocarbon polychlorotrifluoroethylene (PCTFE) technology and specifically engineered for low seal-face-velocity applications operating at elevated processing temperatures. Designed for rotary mixers, agitators, centrifugal pumps, and other dual- or tandem-seal systems, it delivers reliable lubrication and cooling to mechanical seals in both pressurized and non-pressurized applications. The high viscosity of MSLV27 helps minimize environmental or process-side leakage.
All Halocarbon® barrier fluids are also available with anticorrosion additives upon request at no extra charge.
