In some instances, vertical turbine pump are installed into individual cans or suction barrels. When this is done, the pumps are called “canned vertical turbine pumps”, “barrel pumps”, or “can pumps”. Canned turbine pumps are commonly used when pumping hydrocarbons. By doing so pump engineers and system designers can use gravity to increase the amount of suction pressure available to the pumps (NPSHa) to allow them to operate more effectively.
Canned pumps are also common in municipal water applications since the use of cans provides the designer with greater flexibility when designing a pump station.
