Hydraulic piston pumps
BALINIT C (WC/C) - and BALINIT DLC coating of plungers, valve plates or shoes reduce stick- slip of large radial piston pumps and improve service life of axial piston pumps.
Advantages: Friction reduction and therefore less energy consumption by large radial piston pumps, replacement of bronze shoes and valve plates by coated steel parts for higher performance and material cost savings.
