Limestone Slurry Feed Pump

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3).

Limestone has numerous uses: as a building material, an essential component of concrete (Portland cement), as aggregate for the base of roads, as white pigment or filler in products such as toothpaste or paints, as a chemical feedstock for the production of lime, as a soil conditioner, or as a popular decorative addition to rock gardens.

So there are huge demand of pumps can pump the limestone mixed with water, which is limestone slurry. And this is also why the pump called limestone slurry feed pump.

We can offer kinds of pumps to match your working Limestone conditions.
