Roots Pumps (Vacuum Booster) is a positive displacement water pump which is used to increase the pressure of the inlet fluid by compressing it in between the two meshed lobed rotor and then transport it to the outlet discharge valve which is connected to the flow lines of the working system for their efficient functioning. The component parts and the external casing of this machine are fabricated by using premium class engineering grade materials which offers higher strength ad rigidity for longer service life.
