Water Circulating Vacuum Pump Complete Guide

What Is Water Circulating Vacuum Pump?


Water circulating vacuum pump also known as water ring vacuum pump, it is a kind of vacuum pump.

The water circulating vacuum pump improve the space and appearance with transparent anti-corrosion water tank, anti-corrosion shell and stainless steel shellaccording to the characteristics of the small laboratory area.

Water circulating vacuum pump feature in small size, light weight, beautiful appearance, etc.

The water circulating vacuum pump can also be used as a compressor, called a water ring compressor, it is a low pressure compressor.


How to Choose Water Circulating Vacuum Pump?


The working pressure of the water circulating vacuum pump should meet the ultimate vacuum and working pressure requirements of the vacuum equipment.

Usually, the vacuum degree of the water circulating pump is selected to be half to an order of magnitude higher than the vacuum degree of the vacuum equipment.

You should confirm the composition of the pumped gas, whether it contains condensable vapor, whether there is particle dust, and whether it is corrosive.

Correctly select the working point of the vacuum pump.

Each pump has a certain working pressure range, such as: 10-3~10-7mmHg, in such a wide pressure range, the pumping speed of the pump changes with the pressure, and its stable working pressure range is 5 × 10 -4~5×10-6mmHg.

Therefore, the working point of the pump should be selected within this range, and it cannot be allowed to work for a long time under 10-8mmHg.
