Advantages of HYPROSTATIK® hydrostatics with PM flow controllers

General advantages of PM flow controllers

  • 4-5 times the stiffness with comparable data,
  • considerably less oil is required,
  • lower pump pressure required as the pump pressure is fully utilised,
  • considerably smaller pump and motor power required
  • stiffness can be adjusted by varying the pre-loading in holding-strip solutions.

Advantages of using PM flow controllers on guides

  • In many cases, holding strips are not needed if the load directions permit this – with PM flow controllers, there is often no need for holding strips for simply increasing the stiffness.
  • In the case of guides with no holding strips, the stiffness can also be increased significantly by means of negative pressure pockets.
  • On guides with holding strips, the stiffness of the guide can be adjusted largely independent of the load by varying the pre-loading.

Advantages of using PM flow controllers on fast-running bearings

  • significantly less power loss,
  • considerably higher maximum rotational speed,
  • greater stiffness and damping,
  • even fast-spinning spindle bearings can be highly loaded,
  • greater functional safety.

Advantages of using PM flow controllers on lead screws 

  • By using our PM flow controllers instead of capillary tubes, the same or better stiffness as ball screws can be achieved, even though the size of the pocket area is restricted. This is why PM flow controllers are a must when it comes to the manufacture of fully-functional hydrostatic lead screws. 
  • High axial loads are possible because, with PM flow controllers, up to 80% of the pump pressure acts as differential pressure on holding-strip solutions. 

Advantages of using PM flow controllers on fast-running bearings

  • significantly less power loss,
  • reduced displacement,
  • greater functional safety,
  • considerably higher maximum rotational speed,
  • even fast-spinning spindle bearings can be highly loaded.
