Slurries are divided into two main categories: non-settling or settling. Non-settling slurries consist of very fine particles, giving the illusion of increased apparent viscosity. These slurries usually have low wear characteristics, but require very careful consideration when selecting the right pump, as they behave differently from ordinary liquids.

Submersible slurry pump pumps offer many advantages over dry and semi-dry (cantilever) mounted pumps.

Are the pump discharge components suitable for the slurry being pumped?

Fewer and thicker vanes on the impeller. This makes it easier for solids to pass through than the 5-9 vanes on a standard centrifugal pump - typically 2-5 vanes.

Scientists analyzed research that examined how titanium dioxide nanoparticles interact with the brain for a 2015 review published in Nanoscale Research Letters. The researchers wrote: “Once the TiO2 NPs are translocated into the central nervous system through [certain] pathways, they may accumulate in the brain regions. For their slow elimination rates, those NPs could remain in the brain zones for a long period, and the Ti contents would gradually increase with repeated exposure.” After reviewing dozens of studies, the scientists concluded: “Long-term or chronic exposure to TiO2 nanoparticles could potentially lead to the gradually increased Ti contents in the brain, which may eventually induce impairments on the neurons and glial cells and lead to CNS dysfunction as a consequence.”
