Recirculating Water Vacuum Pump

A circulating water vacuum pump uses a high-speed jet of water formed at a constricted nozzle to carry away air, creating a vacuum. It achieves continuous air extraction by circulating water through a tank, making it suitable for processes requiring a stable vacuum environment, such as vacuum filtration and rotary evaporation in laboratories.
Selection
When selecting, focus on whether the ultimate vacuum level and pumping speed match the experimental requirements, check the material's corrosion resistance, consider the water tank capacity and water change frequency, confirm the operational noise and vibration amplitude, verify the interface specifications and equipment compatibility, and compare the energy consumption and maintenance costs.
