Pump selection issue

This post was last edited by wgd101cn on 2017-9-29 at 11:20: a suspension composed of 70% methanol and 30% solid powder particles, with a pH of 7 and a temperature of 70 degrees. Powder particles settle very easily; what type of pump is suitable for transferring this material from the reactor to another device? A mechanical seal is required; there should be 2 meters of horizontal piping at the pump inlet and in the reaction vessel, to prevent blockages in the pipelines and the pump
A slurry pump with an open impeller would be more suitable, featuring a double-end seal. Additionally, the poster needs to provide flow rate and head in order to select a suitable or approximate pump model.

Is that you in the profile picture? Let me help you choose this one
Open impeller, slurry pump, with double-end face seal for mechanical sealing.
Methanol, in powder form; a peristaltic pump could be an option to try. As for a slurry pump, it’s uncertain whether proper sealing can be achieved with it. Diaphragm pumps are also another option to consider.
The output requirements play a major role in determining the pump selection; for now, just tell us about the properties of the medium and the inlet pipeline. The reaction tank should be in a state of agitation; otherwise, everything will settle at the bottom. Also, what is the required flow rate per leaf, and what are the length and height of the output pipeline?
If it can be ensured that the particles will not settle within this 2-meter-long horizontal pipe, many pumps will work; if settlement and blockage occur in the horizontal pipe, then no pump will work
