Two Stage Vacuum Pump

We offer highly efficient Two Stage water ring vacuum pumps. These pumps are better design than single stage vacuum pumps, having advantages of higher capacity at high vacuum and also require low quantity of water which saves lot energy.

Two-stage vacuum pumps develop maximum vacuum of 720 mm of Hg, when sealing water temperature is 30ºC (755 mm of hg baro-metric pressure and suction temperature of 30ºC) and achieves vacuum up to 735 mm of Hg, when sealing water temperature is 15ºC to 18ºC.  Due to the latest technology and design, it so happens that a smaller model may require as compared to a single-stage vacuum pump.

 
In the conventional Single stage vacuum pump the performance after 70% vacuum falls down drastically, whereas the Two stage vacuum pump gives better performance after 70% vacuum. Normally the vacuum pump requires to run consistently between 70 to 90% vacuum.

In first stage, after creating vacuum up to 70% the compressed air / vapour mist with sealing media is led to the Second stage working chamber via crossover manifold. Second stage enhances the vacuum generated by the First stage. This way, two stage water ring vacuum pump gives nearly 50% more volumetric efficiency after 70% vacuum with the same electric motor rating. This results saving of nearly 50% energy.
