What Is a Canned Motor Pump?
A canned motor pump is a type of pump that uses a sealed, self-contained motor to drive the pump mechanism. This makes it an ideal choice for applications where leakage could be problematic, such as in chemical processing or nuclear power plants. Canned motor pumps are also very efficient since there is no need for a coupling or other mechanical device to transfer power from the motor to the pump.Canned motor pumps come in various designs, but they all have one thing in common: the motor and pump are contained within a single housing (or "canned"). This housing is typically metal, although some plastic accommodations are also available. The housing is usually filled with lubricating oil, which helps to cool the motor and pump as well as protect them from the environment.
