Please help me choose a pump! Thank you all!

The specific process parameters for pump selection are as follows; 1. Flow rate: 6–10 m³ per hour. Head: 32-50 meters. Suction lift: 2-4 meters. Motor explosion protection. 2. Material information ; Density ; 1. The usual temperature is 105°C, with a maximum temperature of ; 110°C. The sulfuric acid content is 30%, so a pump resistant to corrosion is required. The presence of methanol inside will cause severe cavitation. 3. The key requirement is self-priming, and the diameter of the container’s opening is DN150 (this cannot be changed). 4. Please help and choose one! Thank you

As long as it’s a centrifugal pump, it’s impossible to achieve self-priming under these operating conditions; don’t waste your effort

Hello, I chose a pump; it wasn’t specified that it had to be a centrifugal pump Any pump will do, as long as it can meet my current usage requirements!

I’m not entirely sure about your specific situation. As far as I know, centrifugal pumps are generally used in such cases. If you really need self-priming, positive-displacement pumps might work, but the cost would be very high and there would be significant wear and tear. With methanol present and an operating temperature of 105°C, it’s impossible to achieve successful self-priming under these conditions. If there’s even a slight chance, consider lowering the installation position of the pump

For this application, a sliding vane pump is the best choice – it has strong self-priming capability and can handle the transport of both liquid and vapor. Please leave me your contact information so I can get in touch with you

I know too, but reality is cruel.

It seems that a perfluorinated pneumatic diaphragm pump should be chosen for this pump. I’ll have my colleague get in touch with the poster.
