Manufactured by: Chesterton
Model: 4400
Sales Territory: Indiana

A seal for all purposes! The 4400 bridges advanced gas seal technology to the practical world of process pumps with common installation practices and no special training required. A self contained "in gland" control system makes it possible to install like a standard cartridge seal. Just pipe the gas supply to the gland inlet and start the pump.
