New product: We have started selling the split-type mechanical seal (smart seal housing)!
Say goodbye to the heavy labor of replacing mechanical seals! With SEEPEX's original disassemblable mechanical seal, you can replace it quickly and easily! Until now, the task of replacing mechanical seals in single-screw pumps required disassembling everything except for the drive unit (including the surrounding connection pipes, suction casing, and pulling out the stator), making it a very tedious job that could take several hours even for relatively small types. The disassemblable stator type 'SCT' pump was developed with a focus on achieving quick and easy maintenance. As part of the development philosophy of this pump, the disassemblable mechanical seal 'Smart Seal Housing' was created. With a special mounting tool available as an option, you can adjust the mechanical seal-equipped shaft to the correct position relative to the drive unit when attaching it through the casing to the drive shaft. *For more details, please refer to the catalog PDF or feel free to contact us.
