1. Low noise, low vibration, long service life Magnet fixing method, safe and convenient

2. It can be equipped with a stainless steel oil mist filter, with an independent oil tank design and oil mist catcher to prevent the oil mist from dispersing in the air, thereby reducing air pollution in the laboratory

3. It can be used in experiments with high flow rate and medium to high vacuum degree in the laboratory, such as vacuum drying oven, vacuum filtration, vacuum oven, centrifugal concentrator, etc.

1. Keep the pump clean and prevent debris from entering the pump.

2. Maintain oil level.

3. After storage, when water or other volatile substances enter the pump and affect the ultimate vacuum, open the gas ballast valve to purify it, and observe the rise of the ultimate vacuum. If it is invalid for several hours, the pump oil should be replaced, and it can be replaced again if necessary. Oil change method: run the pump for about half an hour to make the oil thinner, stop the pump and drain the oil from the oil drain hole, then open the air inlet and run for 10-20 seconds, during which time a small amount of clean pump oil can be slowly added from the suction port, To replace the oil in the pump chamber.

4. When disassembling and washing the internal parts of the pump, generally wipe it with gauze. When metal debris, sand and mud or other harmful substances must be cleaned, they can be scrubbed with gasoline, etc., and can be assembled after drying. Do not soak in gasoline.

5. If the pump needs to be disassembled for cleaning or maintenance, attention must be paid to the disassembly and assembly steps to avoid damage to the parts.
