Seek solid-liquid corrosion-resistant transfer pumps
Thread Content
I have a medium consisting of ethyl acetate, with 25% solids and a temperature of 30°C; it also contains 15% hydrogen chloride. I am looking for a transfer pump that is resistant to solvents and acids and does not leak. Which type of pump would be suitable?
15m3/h, 12m. Do you have any suitable pumps to recommend?
Consult a manufacturer specialized in diaphragm pumps. The diaphragm pump should be suitable
Okay, thank you. I’m currently looking at slurry pumps, diaphragm pumps, and hose pumps. Slurry pumps come with mechanical seals, but I’m worried about leaks; diaphragm pumps can handle high solid contents, and I’m not sure whether the diaphragm might wear out and cause leaks
For this pump, a pneumatic diaphragm pump with a 40-inch diameter is the preferred choice; it should be made of PP material, with a diaphragm made of SP or PTFE. PP material balances the solubility of ethyl acetate and the corrosiveness of HCL; it may not last forever, but it’s fine for short periods of time. The price is relatively low as well. If a hose pump is chosen, the material for the pipes should also be EPDM; using perfluoroelastomer is certainly not practical.
It depends on what the solid is specifically. Diaphragm pumps can transport materials containing solids; PTFE and similar materials work well for this purpose.
EPDM is not as good as FKM for handling hydrochloric acid, right?
If using a pneumatic diaphragm pump, consider the particle size of the solid particles in the material
Of course, pneumatic diaphragm pumps made of pure PTFE or lined with PTFE are better, but they are expensive. The basic requirements of PP can be met.
Slurry pumps are the most cost-effective; it is best to choose slurry pumps with mechanical seals and flushing functionality
