SICAL3D with DTS10 bearings

General Applications
Hydraulic external gear pump and motor applications with performance in mechanical and volumetric efficiency above 90%.

High Performance Applications
Hydraulic external gear pump and motor applications with performance in mechanical and volumetric efficiency above 93%. 
Also, for demanding applications including fan drives and automotive steering systems.

Specialty Applications
Hydraulic external gear pump and motor applications with performance in mechanical and volumetric efficiency above 95%. 

In particular, for demanding applications which require:

  • Tight tolerance control on diametric oil clearance and gear teeth meshing for silent pump running for fork lift trucks and for bi-rotational motors
  • Reduction in pump vibrations and improved pump alignment for flow dividers
  • Lower friction for improved running for motors during the start phase
  • A complete bushing block assembly incorporating the pressure relief valve and compensation seals

Besides world class products, unmatched technical support and the latest process innovations, GGB is committed to partnerships which enhance hydraulic solutions in gear pumps and motors.
