MTM733

Limiti d'impiego

Product description

Stationary double cartridge mechanical seal for installations on single screw pumps.
Sturdy and compact, it has been specially designed to be easily disassembled without having to remove the pump support. The replacement cartridge, in fact, guarantees an important reduction in pump maintenance times. Balanced and with springs protected by the process fluid, it is the most innovative product intended for this application.
