Looking for pump recommendations
Thread Content
Liquid materials with a viscosity of 60,000 mPa·s and a specific gravity of 1.5+; flammable, packaged in ton barrels. It is required to pump the material in this tank into a trough within 5 minutes. A hose should be inserted through the open top of the tank to draw out the material. Please recommend a suitable pump. Thank you.
It seems that a gear pump would work, but it also depends on whether it meets the requirements dictated by the physical and chemical properties of the material. For reference.
A pneumatic diaphragm pump can be chosen, as it offers higher efficiency
A diaphragm pump might be a better choice; after all, if a centrifugal pump is selected, one also has to consider the mechanical seal. For this viscosity level, using a mechanical seal is a bit complicated and troublesome. Diaphragm pumps are better. It’s hard to say anything about their efficiency; I’m not very familiar with how diaphragm pumps work, but these pumps don’t require seal rings and use balls for sealing instead
Diaphragm pumps are recommended; they are resistant to acids and alkalis, have a self-priming function, and are not prone to damage.
