"The iglidur® X was chosen as gliding material for the guidance of the surface-hardened stainless steel piston rod due to the temperature resistance and adequate humidity resistance, and also due to the absence of glass fibers (piston rod protection). Advantages in this application compared to conventional European piston pumps:
Just one slide valve instead of two (newly developed control logic)
Oil-free (tribological pairing of PTFE/ceramic and hardened stainless steel/iglidur® X)
Extreme probability of absolutely reliable operation (compared to old versions). ”
