Multi Spring Balanced Seal MSOB 230 Series & MSWB 240 Series

 

Quba’s Multi Spring Balanced Seal MSOB 230 Series & MSWB 240 Series are multiple spring units developed for universal high pressure application. Their compact design makes them suitable for use in all types of Centrifugal pumps. Torque transmission from retainer shell to seal ring is done through drive lugs. All components are held together by a snap ring which makes installation and removal easy. As all parts are interchangeable, so Series MSOB 230 can be converted to Series MSWB 240 by changing only the seal ring & the elastomer and is ideal for stock rationalisation.
