Pompe Pollard P258

  • The P258 to P56 pumps are designed to pump lubricating fluids (oil, diesel oil, etc.)
  • Their flow rate is from 1 to 500 L / min; maximum working pressure 10 bar
  • The Pollard “CMtec” technology guarantees good volumetric efficiency, good suction capacity and the ability to pump viscous fluids.
  • These robust industrial pumps are designed to provide continuous service for many years.
  • For any request, not included in the catalog, a feasibility analysis can be carried out by our design office on simple demand.
