Series 40
Multispring Seal
Balance - Wedge / 'O' Ring Type
Type: 40B and 45B
Series 408 & 458 are multiple spring balance seal with O-Ring as secondary sealing member in series 408 & wedge as a sealing member in 458. Various face material & elastomers can be offer for wide service application. The compact design of seal permits their use in all types of centrifugal pump. As all parts are interchangeable, one can convert series 408 to series 458 by changing only seal ring, secondary packing and mating ring packing. This concept is ideal for stock rationalization
Type 40B
Secondary Seal Material: Viton / Buna / EPDM or Neoprene “O” Ring in order to ensures less shaft fretting due to capacity for flex and roll. “O” Ring Seals are preferred where elastomer are suitable for process fluid.
Туре 45B
Secondary Seal Material: PTFE/GFT Wedge in order to ensures seal operation on high temperature and Chemical Application
