  • Accurate machining insures proper meshing, and reduces friction and vibration.

LONG-LASTING WEARING SURFACES
  • Bearings are special wear-resistant, high-lead bronze. Iron and carbon bearings are available.
  • Four heavy duty sleeve bearings give positive support to pumping gears and insure long, efficient service.
  • Bearing grooves allow circulation of the liquid being pumped for lubrication and control of bearing temperature.
