Tobee®D3147BFA05 Back full Impeller is used for 4/3C-AH Slurry Pumps, it also installed on 4/3D-AH Slurry Pump.
An impeller is a part of a pump or compressor that rotates at a high speed and acts as a propeller to increase a fluid's pressure and flow rate. Impellers are made from various metals such as steel, iron or bronze, as well as plastics. The impeller transfers energy to the fluid as it passes through the pump, which increases the fluid's velocity at the pump's discharge outlet.
There are three types of impellers: Open impeller, Closed impeller, Semi-open impeller
An impeller's speed of rotation is typically measured in revolutions per minute (rpm). An impeller increases the velocity of a fluid (a liquid or a gas) that is forced through a tube at an increased pressure. Pumps and compressors that use impellers are commonly used to transport fluids and gases in pipelines over long distances.
