Manzel Model HP-50 High Pressure Lubricators 

For lubricating compressor and circulator cylinder walls, heavily loaded bearings and other moving parts

Σημεία πώλησηςΑίτημα πληροφοριών

Single plunger force feed design is highly efficient for injecting lubricants and/or compatible fluids into high pressure systems. Vacuum sight feeds on self-contained pumping units show output of lubricant to individual lubrication points.

  • All working parts are totally enclosed and self-lubricated
  • Individual pumping units easily removed for service
  • Feed rate infinitely variable from minimum to maximum with simple hand adjustment
