This is a still representation
and possibly also a low-resolution image of a fully animated pump.

|
By having only two vanes, the risk of clogging from foreign matter in the
fluid being pumped is reduced over a pump with more vanes. (For even messier
fluids a single vane can be used.) |
|
This type of pump might be used for pumping sludge or other contaminated
liquids. It is also common for moving liquid paper stock. |
|
All of the head in an impeller type pump is created by the impeller itself.
The rest of the parts induce losses to the maximum head. |
|
Losses are induced by friction of the fluid against the sides of the parts,
by mechanical friction of the pump shaft, and from hydraulic efficiency
losses such as fluid eddies and changes in direction (which takes energy). |
