Cadmium is a metal found naturally in the earth's crust. Pure cadmium is a soft, silver-white metal; however, its unusual to find it in its pure form. Its commonly found in combination with other elements such as oxygen (cadmium oxide) or sulphur (cadmium sulphate).Cadmium is also used in industry.The cadmium used in industry is a byproduct of zinc, lead, and copper refining. Industrial uses of cadmium include production of metal plating, rechargeable batteries, paint pigments, and plastics.admium is also used in industry.

Submersible pumps are made, as their name implies, to be submersed within a tank, well, or other container. Manufacturesâ of submersible pumps design many common types of pumps to make them suitable for immersion.ire and Rescue Services. Submersible pumps are used to pump out water to a minimum depth of 15 cms or from open water to supply an incident ground with water. Submersible pumps can be lowered into a subway or down a cliff into open water and still operate.
The submersible pump lies horizontally in the bottom of the cistern which allows all but the bottom 5â³ of water to be used in the cistern. The pipe from the pump is connected to a union or pitless accessible from the manhole. That way the pump can be replaced while the cistern is full of water. Inside the cistern, we build a unique manifold assembly that connects to the union from the pump; the electric float switches (or the float valve) is mounted to it and the water line feeding the cistern is part of the manifold.
