Low torque seal for water pumps



・Reduces torque by more than 90% compared to the conventional mechanical seal.
・The unitized seal design enables simple installation into customer's application.
- Less noise potential due to non-contacting surfaces.


Textured sealing technology brings two contraries together: extremely low torque and superior sealing performance.
Its non-contacting sealing under rotation provides low torque with improved wear resistance.

Similar to our conventional seal design (EH795), the rotating and stationary components are unitized with the stamped sleeve, providing ease of installation as well as high reliability by protecting sliding surfaces.
