Selection of sodium chloride slurry transfer pumps
Thread Content
The solid-liquid ratio of the sodium chloride slurry is 7:3; the liquid phase is a saturated solution of formic acid, and the temperature ranges from 80 to 100 degrees. The material is discharged directly from the bottom of the reactor. Each batch of sodium chloride slurry, amounting to 1.5 tons, is removed intermittently and then pumped to another reactor. The transfer pipeline is kept at a temperature of 70 degrees, with a horizontal transmission distance of 40 meters and a lifting height of 6 meters. I previously found that both diaphragm pumps and screw pumps don’t seem suitable for this application; guys, could you give some suggestions?
A hose pump can be considered, but the poster still needs to provide additional data; details can be found in the message box.
Have you used a pump for transportation before? Also, there should be an agitator inside the tank
It’s a new project; I haven’t tried it before. The reaction vessel has an agitator, but the feeding process must be stopped while the agitator is running, as there is still an oil layer on top that needs to be separated into different phases
Stop stirring; the solid phase will then be entirely at the bottom. Is the solid phase in a paste form or in granular form?

The solid phase is granular, with particle sizes ranging from 0.2 to 0.5 mm
If the solid-liquid ratio is not mixed evenly, it is difficult to transport; this is equivalent to transporting the solid phase first and then the liquid phase
This pump must meet the following requirements: 1: It should be suitable for transporting media containing particles, allowing the simultaneous transport of solids and liquids; 2: It must be able to operate without fluid/under dry conditions. A gas-powered slurry pump can be used, with a cyclonic impeller being the appropriate choice for the impeller type
I also need to take into account the issue of chloride corrosion here; the concentration is very high. If the flow-through parts of the pump are made of metal, then it should be titanium
Yes, screw pumps are not very suitable, and chloride ions also pose strict requirements regarding the material used for the screws
