Series 30 – Multispring Seal Overview
Unbalance Wedge / 'O' Ring Type
Type: 30U and 35U
Series 300 and 35U are multiple spring-unbalance seal with Wedge as secondary sealing member in series 300 and ‘O’ Ring as a sealing member in 35U. 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 300 to series 35U by changing only seal ring, secondary packing and mating ring packing. This concept is ideal for stock rationalization.
These Seals can be easily assemble or dismantled through circlip provided & can be change to Balance version by merely changing the carbon face only & can be provided with single, double or tandem arrangement with external seal support systems & devices
Type 35U
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 30U
Secondary Seal Material: PTFE/ GFT Wedge in order to ensures seal operation on high temperature and Chemical Application
