Hua Marine Service Co.,Ltd provides ejectors by materials of Bronze & Stainless steel & Titanium alloy . An ejector is a vacuum pump that does not have any mechanical drive parts. Instead, it is driven by injected steam or similar mediums. It has a simple construction for virtually trouble-free operation. And it is easy to be manufactured for large volume rate. Standalone ejectors can compress up to atmospheric pressure, and can be used in series to attain even higher vacuum pressure. They can be used with other vacuum pumps to build a vacuum system. We can develop new product by samples or drawing.
