PWO are three-spindle screw pumps designed to convey cooling lubricants (emulsions and cutting oils) for high pressures in high machine tools/filtration system applications.
Typical configurations for vertical mounting on tank with pump submerged and delivery port above the tank.

PWO pump is typically used also for lube oil systems and fuel oil supply systems at high pressure in the Oil&Gas industry.
It is a versatile pump and can be installed in horizontal or vertical position, both pedestal or submerged in the tank.

Main features & benefits:
✅ Pump housing and screw set specially hardened ensure optimal service life
✅ Hydrostatic thrust compensation to minimize frictional effects and thus wear and tear
✅ Low pulsation and noise
✅ Long operational life and minimal maintenance
✅ Shaft sealing with lip seal or mechanical seal with leakage identification
✅ Version available with pressure relief valve with direct discharge into the tank
✅ Motor-pumps available with integrated or remote drive control to save energy based on the need of each specific working condition
✅ Component mechanical seal
✅ Self lubricated ball bearing
