- 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.
