The Ejector M 300 C ( from 200 g/h up to 15000 g/h) - 36931 M 300 C

General: The Ejector is a mechanical device that generates the necessary vacuum for functioning of the dosing system. It con-sists of a drive nozzle, mixing chamber, non-return valve and an outlet connection. Ordinary ejector construction is for pipes with water pressure up to 6 bar. Reinforced ejectors are used for pipes with water pressure more than 6 bar. Ejectors with “connection cock” are used when the ejector has to be separated from the pipeline in which there is overpressure. Operation: The booster pump drives water through the ejector. This generates vacu-um, the power of which depends on the pump pressure and permeability of the dri- ve nozzle. Vacuum fills the ejector with gas chlorine which mixes with water in the mixing chamber. The mixture of chlorine and water is then injected into the water- supply system. The non-return valve pre-vents irruption of water into the vacuum line.
