JZJA(P)LG Screw pump system

Introduction:

JZJA(P)LG series Screw vacuum pump system belongs to oil-free dry vacuum system, with roots pump(main pump & secondary pump), dry screw pump (fore pump). Roots pump is similar to screw pump in working principle and structure. The vacuum system could be assembled reasonably as per the size of pumped system, vacuum receiver and its working pressure. The available suction ratio ranges from 1:2 to 1:8 among variant pump.

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.

Application:

It can be widely applied in industry like medicine, chemical, aerospace, electrical, solar energy, metallurgy, and food industry. In chemical industry, it is necessary for process of vacuum distillation, vacuum evaporation, vacuum dehydration and crystallization. And in electric industry, for process of vacuum impregnation and vacuum drying. Beside, it’s the ideal choice for vacuum coating, vacuum melting, thermal treatment, oil filtration, vacuum freezing, space simulation test, etc.
