PWE 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.

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
