Product overview

It is more advantageous for the vacuum unit to select the water ring pump as the front stage pump than other vacuum pumps. It overcomes the shortcomings of the limit pressure difference of a single water ring pump (the limit pressure of the unit is much higher than that of the water ring pump) and the low extraction rate under a certain pressure. At the same time, it retains the advantages that the water pump can work quickly and has a large extraction rate.

Product features

1. Simple structure, low manufacturing accuracy requirements, easy processing, simple operation and convenient maintenance;

2. The structure is compact, the pump is generally directly connected with the motor, and the number of revolutions is high. With a smaller structure size, a larger exhaust volume can be obtained;

3. There is no metal friction surface in the pump cavity, so there is no need to lubricate the pump. The seal between rotating parts and fixed parts can be directly completed by water seal;

4. The temperature change of compressed gas in the pump chamber is very small, which can be considered as isothermal compression, so flammable and explosive gases can be pumped out;

5. Since there is no exhaust valve and friction surface, dusty gas, condensable gas and gas-water mixture can be pumped out.
