The JZJLG series screw vacuum pump system belongs to the oil-free dry vacuum system, comprising Roots pumps (main pump and secondary pump) and dry screw pumps (primary pump). Roots pumps share similar working principles and structures with screw pumps. The vacuum system can be assembled reasonably based on the size of the pumping system, vacuum receivers, and their operating pressures. The available suction ratio range for different pump models is from 1:2 to 1:8.

Overview:

Advantage:

1) With both advantage of roots pump and screw pump.

2) With doubled capacity and high pressure matching with large capacity roots pump

3) Energy saving for large capacity.

4) High pumping capacity in high vacuum pressure.

5) Automatic controlling system

6) Capable for corrosive gas pumping.

7)Small area request with vertical or stepped construction.

8) With self protecting function for over-load, over-fluid, water-break condition.

9) Hard to accumulate dust or particles, specially suitable for condensable medium or dust suction.
