What type of pump should be used to transport toluene?
Thread Content
When there is an electrostatic ground, the flow speed of benzene and liquids with similar properties in pipelines should not exceed 1 m/s. In such cases, how should a transfer pump be selected – a centrifugal pump? Gear pump? Or something else? Please share your opinions and reasons regarding which type of pump should be chosen, and which ones should not be used! This post was last edited by cowboy_ar on 2008-7-1 at 16:23.]
Avoid using gear pumps; centrifugal pumps can be considered. For flammable and explosive materials, shielded pumps are a better choice
It’s mainly the toxicity issue; consider using a shielded pump: lol
What about from the perspective of electrostatic protection? I think centrifugal pumps are not suitable, as the flow velocity inside the pump chamber is high; if the impeller has a diameter of 160 and the rotation speed is 1450, the flow velocity at the outer edge can still reach 12 m/s
We use shielded pumps, or chemical pumps here.
We use centrifugal pumps, and there are no problems. Considering the toxicity of toluene, it is best to use a shielded pump
Canned pump Canned pump Canned pump Canned pump
Choose a magnetic pump – there are a wide range of models available, they have a high degree of domestic production, and their quality is also quite good! The price is also reasonable!
Could you tell me what kind of pump is suitable for pumping toluene in underground tanks?
It should be a canned pump or a magnetic pump + explosion-proof motor; the specific selection is determined based on flow rate, pressure, and cost.
We use shielded pumps; the entire pump and motor are combined into one unit. It’s a canned motor pump, and the brand is Hermetic
