40L / Min Water Circulating Vacuum Pump Liquid Recycled Suction For Rotary Evaporator

Water Circulating Vacuum Pump Liquid Recycled Suction For Rotary Evaporator

Water Circulating Vacuum Pump Advantage

The circulating water vacuum pump uses the rotation of the motor to drive the circulating water and extract the gas in the connecting system, which has achieved the purpose of gradually reducing the pressure in the system. At present, the circulating water pump is often used in the laboratory for decompression filtration and other operations.

1. The water saving effect is obvious. Due to the water circulation operation, the water added to the water tank can be cycled back and forth, which overcomes the phenomenon of wasting a lot of water when the tap water method is directly vacuuming.
2. Multifunctional comprehensive application. In addition to providing vacuum conditions, this machine can also automatically circulate water externally to provide circulating cooling water for the reaction device.
3. Fashionable and easy to use.
4. The machine is equipped with five suction nozzles, which can be used to pump air separately or observe the vacuum degree at the same time.
5. Corrosion resistance, no pollution. The pump parts of this machine are made of stainless steel, and the water tank is made of ABS plastic. It is formed in one time and is not affected by corrosive substances such as acid and alkali.

Water Circulating Vacuum Pump Description

This product is a multi-purpose vacuum pump designed with circulating water as the working fluid and the principle of negative pressure generated by jet flow. It provides vacuum conditions for chemical laboratories. This equipment cannot provide circulating cooling water to the reaction device.
It is widely used in evaporation, distillation, crystallization, filtration, decompression, sublimation and other operations. It is an ideal equipment for laboratories in colleges and universities, medical chemical industry, food processing and other fields.

Operation Instructions

1. Add water before starting the machine. Do not run the machine empty. It is strictly forbidden to open the cover with electricity.

2ˎ Preparation, when using the pump for the first time, open the top cover of the pump box and pour in clean cold water. Stop adding water when the water surface is about to rise to the height of the overflow port. Repeat the boot to stop adding water. However, the longest time is to replace the water once a week. If the water quality is seriously polluted and the usage rate is high, the time for replacing the water can be shortened. The ultimate goal is to keep the water quality in the water tank clean.

3. For vacuuming operation, the suction sleeve of the equipment that needs to be vacuumed is closely connected to the suction nozzle of the machine. Check that the circulating water switch should be turned off, turn on the power supply, and turn on the power switch to start the vacuuming operation. The vacuum gauge corresponding to the suction nozzle can observe the vacuum degree.

4. When the machine needs to work continuously for a long time, the water temperature in the water tank will rise, which will affect the vacuum degree. At this time, the water hose can be connected to the water source (tap water) to keep the water temperature in the water tank from rising. Stabilize the vacuum.
