Energy saving comparison between water ring pump and oil screw vacuum pump used in CNC machining center
Hanbell PA1300 vacuum pump with 22KW motor
When the vacuum demand is reduced, the speed can be reduced automatically thanks to frequency converter, and the minimum load can be reduced to 5 kW.
If the water ring vacuum pump with similar pumping speed is selected. It totally needs 5 sets with pumping speed 1600, and the power consumption is 45kw.
Energy saving comparison: variable frequency screw vacuum pump PA1300 VS water ring pump
Electric charge for one year（RMB 0.8/kWh 6000h）
PA oil-less screw vacuum pump
Water ring pump
Compared to Water ring pump, PA energy saving 51.1%
