The material pump is installed at too high a height
Thread Content
The installed height of the material pump, as calculated, is 2.5 meters; the distance from the bottom of the tank to the pump head is 0.5 meters, with the pump itself being at approximately 1 meter above the ground level. If digging below ground level, it becomes difficult to carry out operations related to heating the pump and discharging material. It’s not easy either to raise the tank by 2 meters; in addition to the heating systems, there are also instrument wires involved, and the issue is that right above is the steel beam from the second floor. I need a solution where there is no movement or only minimal movement.

Is it convenient to drain liquid when servicing a vertical pump underground?
Lift the pump out during repairs； If only the rolling bearings are replaced, the mechanical seal does not need to be taken out; it can be replaced right on the ground.

A larger platform below ground level can be built near the pump to facilitate operator access ； 2. If the space on site does not allow it, a liftable workbench for the pump and instruments can be constructed; pipeline connections can be made using flexible hoses, union fittings, or clamps. In short, there are many ways
Previously, these two pumps often had problems and would shut down due to insufficient power; it was suspected that the filters were clogged, so the filters were regularly cleaned by draining contents, and this should reduce such issues in the future
Add another pump, and one buffer tank each
