Function

This product is a new type vacuum suction pump design based on recycled water as the working fluid, the principle of negative pressure produced by jet. It is provide vacuum for chemical experiments and also can provide circulating cooling water to the reaction set.

The pumps are widely used in evaporation, distillation, crystallization, filtration, decompression, sublimation and so on. It is the ideal equipment in universities pharmaceutical, chemical, food processing and other areas in laboratory.

Technical data

Features

1. Water-saving effect is remarkable. The water in the water tank of the machine can be recycling, which is overcome the phenomenon of large amount of waste water when direct blow down tap water for vacuum. After testing, in one working day, continuous use may save water more than 8 tons, and the water can be use for a long time at a time. It is particularly suitable for tall building laboratory which is lack of water or insufficient water pressure.

2. Multi-function versatility application. This machine can provide vacuum conditions, besides, it also can provide circulating cooling water to the reaction device. This machine is connected to water, through appropriate supplement water, can continuous cycle operation for long time and keeping the inside temperature does not rise, the vacuum does not drop. Different models have different vacuum taps device, ranging from 2-5, the operator can work alone or in parallel operation.

3. Corrosion-resistant,no pollution.The machine shaft made of stainless steel material: the pump head, impeller, jet device and other key components.Using acid, alkali resistance A.B.C engineering plastics, copper, plastic Wang and other materials, plastic materials for the water tank.According to user needs can be freely chosen, is not from the effects of corrosive substances such as acid, alkali solvents and so on and also does not contaminate the laboratory.

4. Novel appearance, easy to operate. The pump head directly immersed in water, minus the complicated water diversion devices.Bottom with brake caster, easy to move, the upper part with detachable table cover, easy to add water, ice or overhaul.

5. The machine running low noise, stable performance. Also have the advantage of a small size, small footprint, light weight and so on.

Instructions
1. Add enough circulating water. Put the machine on the worktable steadily, first use, please open the mouth which is add water, ice. Then, pour into cool tap water, observe the water level float, stop adding water when the water level reaches the best level scale.

2. Power on. Please correctly connected the power cord between the machine and power supply.

3. Vacuum operation. Please let the suction cannula tightly attached to the suction mouth, checking circulating water switch to make it closed, then read out the indicated vacuum degree.

4. Provide circulating cooling water. When you need to provide recycled water to the reaction device, please contact the circulating water device with cannula, and then start the water cycle switch, you can realize the supply of circulating cooling water.

5. Outside the natural cycle. When the machine needs long time operation , in order to prevent the circulating water temperature rising and affect the vacuum effect, we can use a hose connected to water, control the tap water flow properly and let it formed natural circulation state. We also must continuous supplement and replace the cool water to keep circulating water temperature does not rise, it will not affect the vacuum effect.
