What Is a Centrifugal Canned Pump?

Canned motor pump

A centrifugal canned pump is a type of pump that uses centrifugal force to move fluid through a closed impeller, which is sealed in a can-shaped casing. These pumps are typically used in applications where the fluid being pumped is relatively clean and free of particulates or other solids, and where the pressure and flow rate requirements are relatively low.

One of the main advantages of centrifugal canned pumps is that they are relatively simple in design and easy to maintain. The closed impeller is protected within the can-shaped casing, which helps to prevent damage or wear from exposure to the fluid being pumped. Additionally, the simple design of these pumps makes them relatively inexpensive to manufacture, which makes them a cost-effective option for many industrial and commercial applications.

Advantages of centrifugal canned pumps

Another advantage of centrifugal canned pumps is that they are relatively energy efficient. The closed impeller helps to minimize fluid loss, which reduces energy consumption and increases the overall efficiency of the pump. Additionally, the design of these pumps allows for relatively low NPSH (Net Positive Suction Head) requirements, which means that they can be used in applications where the suction conditions are less than ideal.

There are several types of centrifugal canned pumps available, including single-stage and multi-stage pumps. Single-stage pumps have only one impeller, while multi-stage pumps have multiple impellers that work together to increase the pressure of the fluid being pumped. These pumps can be made of a variety of materials including cast iron, bronze, and stainless steel.

Centrifugal canned pumps are used in a wide range of applications including, water supply, irrigation, boilers, washing and cleaning, air conditioning and refrigeration systems, industrial processes, and many more. These pumps are available in a variety of sizes, designs, and configurations to meet the specific requirements of different applications.

In Conclusion

Centrifugal canned pump manufacturers are a simple and reliable option for many industrial and commercial applications. Their closed impeller design protects the pump from damage and wear, and their relatively low cost, low NPSH requirements, and energy efficiency make them a cost-effective choice for many applications.
