    Tips: How to Use Water Ring Vacuum Pump?

    • Set up the pump. Place the water ring vacuum pump in a suitable location that is well-ventilated and has enough space for the pump to operate safely. Ensure that the pump is properly connected to a power source and that the water supply is connected and flowing to the pump.
    • Fill the pump with water. The water ring vacuum pump requires water to create the vacuum, so it needs to be filled with water before operation. Fill the pump with clean water up to the specified level indicated on the pump's sight glass or level indicator.
    • Start the pump. Turn on the power supply to the pump and switch on the motor. The pump should start operating, and the water inside the pump will begin to circulate, creating the water ring necessary for the vacuum generation.
    • Adjust the vacuum level. Most water ring vacuum pumps have controls or valves that allow you to adjust the vacuum level.
