Axial flow pump or mixed-flow pump...............
I’d like to ask – why are axial flow pumps and mixed-flow pumps recommended? Both types of pumps have a high flow rate but a low head pressure. The original poster did not provide parameters such as traffic pressure; it is recommended that the poster provide feedback promptly.
After passing through the centrifugal pump, the calcium hydrogen phosphate crystals change from 30–40 microns in size to 18–20 microns, which affects the quality of the product. I would appreciate any advice on what type of pump would be best to use I’m not very clear about the physical properties of calcium bicarbonate. First, it is necessary to figure out why the value changes from 30–40 millimeters to 18–20 millimeters after passing through the pump. If it is caused by pump shear, a pump with lower shear force, such as a pulsating pump, may be required.
A diaphragm pump can be an option when the flow rate is not high.
It is recommended to use a single-screw pump. This type of pump enables continuous transportation without any shear forces, and it does not damage the crystals during transport, making it very suitable for this application
I agree with what Hengsheng Pump Industry mentioned above – a single-screw pump should be used
Since the original poster didn’t provide detailed parameters, I was referring to one of the possibilities
A cam rotor pump can be chosen, as it causes no shear
If the head is not high, choose a spiral centrifugal pump.
Flow rate: 200 m3/h Head: 80 m
