Travaini is one of the leading global manufacturers of liquid ring vacuum pumps. Travaini TRH liquid ring vacuum pumps are two stage rotating pumps with externally located bearings that are grease lubricated. These pumps are suitable for high vacuum. Liquid ring vacuum pumps are capable of handling non-condensable gas with high volumes of vapours, condensables and liquids. Pump service liquid can be water or other liquids such as oils or solvents to satisfy almost any process requirement. When TRH liquid ring pumps are mated with devices such as atmospheric air ejectors and or vacuum boosters, operating pressures lower than 1 torr are possible.
