PWO
Description
PWO-type 3-screw pumps
· For low viscosity lubro-refrigerant fluids, with minimum lubricating properties (minimum oil: 5%)
· Mineral and natural oils, low-viscosity fuel fluids.
· Flow rate up to 600 L/min
· Admissible delivery pressure (continuous) = 100 bar at 2900 rpm
· Standard use:
- High pressure lubrication and cooling circuits for machine tools
- To pump fluids with low lubricating properties in refining plants.
