Image video of canned motor pump transporting liquid
This video shows how liquid flows inside a canned motor pump.
The difference between a standard pump and a canned motor pump
Standard pumps are produced with the pump and motor located separately and, because they must be coupled for use, the liquid they handle can leak outside the pump from the gaps in the casing through which the rotating axis passes. However, because our canned motor pumps employ a structure in which the pump and motor are integrated and the liquid they transport is sealed inside, it is characterized by being completely leak-free.

The excellent features of a canned motor pump
Since there is no possibility of the pumped liquid leaking out, these pumps are suitable for handling liquid that is harmful to humans, explosive or flammable liquid, expensive liquid, corrosive liquid, etc.
Since no outside air enters the pump, they are suitable for operation in a vacuum, or for handling liquids whose quality changes when exposed to the outside air.
No shaft seal means it is easy to manufacture pumps that can handle systems with high pressure, high-temperature liquids, low-temperature liquids, high melting point liquids, and more.
Because these pumps do not require lubrication oil, there is no contamination of the transported fluid, and the hassles of adding oil is unnecessary.
Since the motor shaft also serves as the pump shaft, the design is compact, lightweight, requires minimal installation space, and is easy to overhaul.
Operation noise is minimized because there is no fan to cool the motor.
