Fnengg Manufacturer Provides a Comprehensive Guide Canned Motor Pump

Canned Motor Pump

Canned motor pumps are a type of centrifugal pump that uses a hermetically sealed motor as the pump’s driving mechanism. They are commonly used in the chemical, petrochemical, and oil and gas industries due to their ability to handle hazardous and corrosive fluids. In this guide, we will provide a comprehensive overview of canned motor pumps and their key features and benefits.

Design and Construction

Canned motor pumps are designed with the motor and pump impeller housed within a single, sealed can. This design eliminates the need for a traditional shaft and mechanical seal, which reduces the potential for leaks and increases the pump’s overall reliability. The motor and pump are also cooled by the liquid being pumped, eliminating the need for an external cooling system.

Materials of Construction

Canned motor pumps are typically constructed of materials that can withstand corrosive and abrasive fluids, such as stainless steel, Hastelloy, and titanium. These materials also provide excellent thermal conductivity, ensuring that the pump’s internal temperature remains stable.


Canned motor pumps offer a number of advantages over traditional centrifugal pumps, including:

  • Increased reliability: The hermetic seal between the motor and the pumped liquid eliminates the potential for leaks and reduces maintenance requirements.
  • Improved safety: The absence of a traditional shaft and mechanical seal reduces the potential for leaks and explosions.
  • Enhanced efficiency: The liquid being pumped cools the motor and pump, eliminating the need for an external cooling system and reducing energy consumption.
  • Greater versatility: Canned motor pumps can handle a wide range of liquids, including hazardous and corrosive fluids, and can be customized to meet specific application requirements.


Canned motor pumps are commonly used in a variety of industries, including:

  • Chemical and petrochemical: Canned motor pumps are ideal for handling corrosive and abrasive fluids in these industries.
  • Oil and gas: They are used in oil production and refining operations.
  • Pharmaceutical: Canned motor pumps are used to transfer clean and sterile fluids in pharmaceutical manufacturing and research.

Conclusion: Canned motor pumps manufacturers are a reliable and efficient option for handling hazardous and corrosive fluids. With their hermetic seal, improved safety, and enhanced efficiency, they have become an increasingly popular choice in a variety of industries.
