What pump should be used for alkaline solutions with crystals?

What’s the temperature? Is it a continuous operating condition? For more details, please contact QQ496521249 at Shanghai Zhuohui Fluids
Temperature: 120 degrees, continuous operation; flow rate: 2.5 m3/h at 0.5 MPa, and 0.4 m3/h at 0.3 MPa. Two pumps
There are pumps specialized for the alkali industry; slurry pumps can also be used.
For low flow rates and low pressures, a regular centrifugal pump will suffice; however, crystallization can occur, which imposes requirements on the shaft seals, and the pipelines need to be cleaned after use
The solid content needs to be over 15%. I’ve seen that slurry pumps and mud pumps can handle solutions containing crystals, but these pumps have high flow rates and pressures; there are few small-sized versions of them. That’s why I’m asking whether there are any other pumps that would be suitable for this purpose
We have pneumatic double-diaphragm pumps from the AD series, imported from France, which are suitable for your application conditions; the material used is stainless steel
Slurry pumps can be used; many manufacturers offer them
