For the production of dimethyl ether, which type of pump is better for feeding methanol – a screw pump or a shielded pump? Please help me out
Of course, shielded pumps are good – they have no leaks and produce little noise. But requiring good operation and maintenance is not an excessive demand.
As a supplementary point: Shielded pumps come equipped with their own recirculation and cooling systems, which help to prevent cavitation to a certain extent. However, their overall cost is relatively high, and they also require specific operational skills.
If funds permit, it is recommended to use a shielded pump
Our company uses magnetic pumps, and they work well; you can consider them. Magnetic pumps available in China are of high quality!
We use shielded pumps, which perform well and basically require no maintenance
