Benzene recovery (solvent recovery) screw vacuum pump oil-free screw screw pump Features: 1. No oil and water, energy and environmental protection; 2. The world's first low-speed screw vacuum pumps, bearings extend seal life and reduce vibration and noise; 3 Good solid discharge capacity, can compress the condensate discharge, dust, small particles; 4. pumping gas without secondary pollution, gas-free oil and water into the pump chamber, pumping gas is not secondary pollution, protect the environment; 5. engage in a very strong resistance, screw and flow components can be pumped through the coating corrosive gases, particularly suitable for chemical applications, our company can customize all stainless steel screw vacuum pump to apply to more complex conditions ; 6. sealing material is PTFE, durable; 7. Using the closed water-cooled motor is really screw pump motor is currently the highest level; 8. Set the inlet nitrogen purge to deal with complex conditions. Applications: solar energy, chemical, pharmaceutical processes, solvent recovery, molding, dry etching, sputtering, vapor recovery.
