Water ring vacuum pump can attain an ultimate pressure of approximate 25Torr, but here the pumping speed is 0. In order to increase the pumping speed when the pressure range is 1Torr to 30Torr. Water ring vacuum pump can be combined with air ejector pump. Except possessing of the water ring vacuum pump’s performance, the ultimate pressure of approximate is increased 5Torr and fifty percent of the water ring vacuum pump’s nominal pumping speed can be attained in a pressure range between.
