Cartex series cartridge single mechanical seal, balanced design, independent of direction of rotation. Available in no connections, with flush, with quench + lip seal and with quench + throttle ring variants. Suitable for centrifugal pumps and eccentric screw pumps.
Product Description：
Cartex Single single-end mechanical seal is a universal standard industrial cartridge seal with integrated modular design, fully pre-assembled before delivery without on-site disassembly and commissioning. It features stable structure, good wear resistance and reliable sealing performance. Mainly suitable for conventional working conditions of clean water, oil products and slightly corrosive media, compatible with most industrial centrifugal pumps, pipeline pumps, circulating pumps and general process pumps, serving as a cost-effective universal solution for industrial fluid sealing.
Cartex series offers multiple configuration options for different applications:
– Without connections, for dead-end operation
– With flush connection, for applications requiring flushing/cooling
– With quench connection + lip seal (NBR or PTFE), for unpressurized quench operation
– With quench connection + throttle ring (PTFE carbon-graphite reinforced), for quench auxiliary sealing
