Style 777 SW
Designed to “double” seal all double sealing requiring applications. Three FAIL-SAFE features guarantee maximum performance:
SAFETY SEAL: Through the incorporation of a low specific gravity barrier fluid at a higher (to the pumped fluid) pressure, guarantees a NO LEAKAGE SEALING concept. Ideal for low lubricity and high abrasion fluids in MIXERS and AGITATORS.
TANDEM SEAL: Through the incorporation of a barrier fluid at a higher pressure to the system pressure offers good sealing in higher pressures and improved PV factor for extended maintenance free seal life.
STAND-BY SEAL: Barrier Fluid at Atmospheric Pressure used on the back-up secondary (safety) outside seal, ensures unexpected seal failures, resulting to costly shutdowns.
