Fundamentals Of Pumps

Pumps of this type are called double volute pumps (they may also be referred to a split volute pumps). In some applications the double volute minimizes radial forces imparted to the shaft and bearings due to imbalances in the pressure around the impeller. A comparison of single and double volute centrifugal pumps is shown on Figure 2.

Honda Pumps How Pumps Work

All pumps use basic forces of nature to move a liquid. As the moving pump part (impeller, vane, piston diaphragm,etc.) begins to move, air is pushed out of the way. The movement of air creates a partial vacuum (low pressure) which can be filled up by more air, or in the case of water pumps, water.

The heart is a double pump (article) Khan Academy

As a result, the left ventricle (pump #2) forcefully pushes the blood through the arteries and capillaries of the body to get to the trillions of cells in need of oxygen. For the return trip, blood travels through the veins of the body to get back to the right side of the heart and repeat the process. So there you have it – one heart – two ...
