Can toluene and ethanol be pumped using gear pumps?
Thread Content
-Can it be discharged using a gear pump at 20°C under vacuum conditions (-0.08 MPa)? The pressure is at atmospheric level after the pump; please give some advice.

First of all, the poster mentioned that the toluene and ethanol at the outlet of the gear pump are at atmospheric pressure, meaning they are in contact with the atmosphere; the poster intends to empty these two substances, which is extremely dangerous! Strictly prohibited! ! ! . Secondly: If the poster ignores my advice and continues to use a gear pump to transfer fluid into containers or pipes, a safety valve should be installed there to prevent pressure buildup. Please have the original poster take a look at Article 3 of 5.5.1 in GB 50160-2018, the Code for Fire Protection Design of Petrochemical Enterprises

Shielded pumps and magnetic drive pumps are used for transporting hazardous materials such as those that are flammable or explosive; they have the advantage of preventing leaks. Meanwhile, the transportation equipment and pipelines must be equipped with systems for dissipating static electricity, and electrical equipment should also be of explosion-proof type

We have a vacuum discharge gear pump that can deliver material smoothly at a pressure of -0.099 MPa. If you’re interested, you can add me as a friend: 13313170275 (the same number on WeChat)
