I’m facing difficulties in selecting a pump; I hope experts can help me figure this out
Thread Content
Material: Petroleum ether (a mixture of pentane and hexane). Has anyone come across it? What pump is used for transportation? The material is volatile, so a pump that does not leak must be chosen. What material is good to choose?
A magnetic centrifugal pump with overflow components made of stainless steel will do. There is no problem using this type of pump to transport aqueous solutions of monomethylamine
In such cases, magnetic pumps or shielded pumps are generally chosen; the material is not an issue – S30403 will suffice
For shielded pumps or magnetic pumps, I think diaphragm pumps can also be used for small volumes.
As a supplementary point, if the net positive suction head is severely insufficient, one can consider using a cartridge-type shielded pump, which combines the features of both VS6 pumps and shielded pumps; by burying it underground, the NPSHa can be increased, and its shielding function helps to prevent leaks
