The hydro ejectors are designed to evacuate or supply water via the ventury effect.The portion of the pressurized water in the converging and diverging pipes creates a vacuum that causes the suction of the liquid to be discharged. A non-return valve, mounted at the base of the apparatus prevents priming. A filter screen of 1/4 inch prevents the suction of impurities or pebbles. A flush with a ring allows the drain at a distance of the column after use. Several holes allow the attachment of the device with a rope to ensure safety. The amount of water that is available to evacuate in a given period of time depends on: - motive water pressure at the inlet of the device - the geometric height of discharge (difference of the level between the water to be evacuated and the outlet of the discharge pipe).
