vacuum pump 440

Chemical hybrid pump is a two-stage rotary vane pump and a two-stage chemical diaphragm pump combined together to achieve the ideal corrosion resistance. Diaphragm pumps are used to maintain the vacuum in the oil chamber, keeping the partial pressure of solvent vapors below their dew point, greatly reducing the condensation of oxidizing or corrosive gases.

【 Performance performance 】

1 Reduce internal corrosion, even when extracting corrosive gases

2 Reduced oil consumption by more than 90% compared to a single rotary vane pump

3. Efficient solvent recovery system makes it an environmentally friendly product

4. Adopt "mirror barrel" type design, easy to maintain

【 Key features 】

1. The maximum pumping speed of the machine at 50Hz is more than 5.9m3 /h;

2. There are two stage rotary vane pump and two stage chemical diaphragm pump composite, the whole machine has only one motor, easy maintenance;

3. The maximum pumping speed of chemical diaphragm pump end is not less than 1.9m3 /h;

4. The maximum pumping speed ratio between the rotary vane pump end and the diaphragm pump end is less than 3:1;

5. Limit vacuum (unventilated town)≤ 2*10-3 mbar;

6. Limit vacuum (open gas town)≤ 1*10-2 mbar;

7. Water vapor tolerance >> 40 mbar;

8. Ambient temperature range (operation) 12-40 °C;

9. Rated motor power ≤ 0.37kW;

10. Rated speed ≥1500 min-1 at 50Hz;

11. Standard maintenance indicator mechanical table and air outlet oil mist filter;
