The electric pumping unit is unable to extract the remaining residue at the bottom
Thread Content
I use an electric oil pump to draw the amine solution out of the tank, but there’s always about 5 centimeters of liquid that cannot be drawn out and remains behind. We thought of adding a section of pipe below the gear to connect to that area, but even after doing that, we’re still unable to draw out the liquid. I don’t know why Does anyone know the reason? Extra points.
This pump can only lift water to such a height; using pipes is useless in this case
I can’t draw it in; the self-priming capacity is just that limited
Try a pneumatic diaphragm pump; it has excellent self-priming capability
Use a pneumatic diaphragm pump for pumping it. When we were still installing sulfur and had not yet started the acidic water treatment process, we used a pneumatic diaphragm pump to pump the acidic water into buckets, so that basically none of it remained in the buckets
The ordinary gear pump we use works quite well for pumping; basically no fluid remains at the bottom of the tank
