Temperature: 50 degrees. Pump flow rate: 60 m3/h. Inlet pressure: 0.11 MPa (absolute pressure). Outlet pressure: 0.611 MPa (absolute pressure). Pressure difference: 0.6 MPa. NPSHr: 5 m. Selection requirements: Gear pump that complies with the AIP676 standard, along with an explosion-proof motor. Response requirements: 1. The type of pump; manufacturers can be recommended. 2. Materials used for various components of the pump. 3. Pump speed and shaft power. 4. Power of the motor required. 5. Other suggestions

Take a look from above; what kind of selection is it?
Dalian Pump Industry – the ones we use now work fine

Why not choose a centrifugal pump – efficiency issues? Take a look. . .
I have had experience choosing pumps before, but I’m still confused and don’t know where to start. I hope to learn more from this activity.
Sorry, I’ll move it to the bottom; let’s take a look at other people’s answers
This post, well, you can’t read it without replying. Replies without any actual experience are just nonsense; such replies result in points being deducted from your account. How am I supposed to learn then?
