Performance Standard

DYNAVIS®

Hydraulic Fluid Performance

Have a look at the most important performance requirements for three hydraulic fluids formulated to the DYNAVIS® standard!


Though ISO viscosity grades differ, they share the extremely high viscosity index of at least 160. The guaranteed minimum energy savings range from 3.5 to 5 percent in a Denison T6C vane pump.
The longevity of ISO 32, 46 and 68 DYNAVIS® formulations is secured by minimum KV100 viscosities after shear of 5.9, 7.5 and 10.0 cSt, respectively.
