HOME / PRODUCTS / MECHANICAL SEALS / DUAL CARTRIDGE MECHANICAL SEALS / MECHANICAL SEAL STYLE 79
FEATURES:
Incorporated pumping ring improves the movement – and the cooling effect – of the barrier fluid during operation
Tandem design maintains product and barrier fluid on O.D. of both seals for increased safety and heat dissipation
A tangential connection maximizes the flow of barrier fluid
Can be operated in pressurized or non-pressurized state configurations
Springs are located out of the product
Double balanced inboard face allows for reverse pressures in upset conditions
Easy to install cartridge design
Fits ANSI standard and big bore pumps
Metric sizes are available
