P750VK Standard Cartridge

Description

Our Double P750VK Standard Cartridge is designed according to API 682 / ISO 21049 regulations. It has multi-spring rotation and is suitable for pressure inversion. There is the possibility of adding an integrated pumping device and designing it bi-directionally.

Its field of operation is extended in terms of temperature and pressure. It adapts to any sealing chamber and as for its metal parts, they are also available in special materials. The torque transmission of this type of mechanical seal is optimized. In addition, the operation of the seal is completely safe thanks to said transmission of metallic torque in the rotating stationary part.
