The piston rod of today’s high-pressure injection pumps
moves with a frequency of more than 200 Hertz.
This calls for an extremely wear- and heat- resistant seal.
The Duo Forseal stands up to these stresses-
even after more than a billion strokes.
As a result, high-pressure pumps can function
efficiently and remain trouble-free during
the long service life of a commercial vehicle.
