Why Choose a Canned Motor Pump and Advantages and Benefits Explained?

When selecting a pump for industrial or commercial applications, there is an array of choices available on the market. One less-known but highly efficient type is a canned motor pump.

In this blog post, we’ll cover why choosing this type of pump is beneficial and outline its features and advantages.

What is a Canned Motor Pump?

Canned motor pumps are centrifugal pumps designed with their motor and impeller inside an outer casing, commonly referred to as a “can.”

Unlike traditional pumps, canned motor pumps don’t use shaft seals or couplings between the motor and impeller, eliminating potential leakage risks and improving overall reliability.

Advantages and Benefits of Canned Motor Pumps:

Zero Leakage:

As previously stated, canned motor pumps do not feature a shaft seal that could potentially leak, making them ideal for handling hazardous and toxic liquids which could potentially leach into the environment or damage equipment if leaked.

This feature makes canned motor pumps ideal for dealing with hazardous and toxic liquids which could pose risks if leaked into the environment or caused any environmental harm

Low Noise and Vibration:

Canned motor pumps feature an integrated motor and impeller that reduces noise and vibration levels.

This makes them perfect for applications where noise reduction is a priority, such as hospitals, laboratories, or residential buildings.

Energy Efficient:

Canned motor pumps are engineered for efficiency, which lowers operating costs and minimizes your facility’s carbon footprint.

Since they don’t require shaft seals, you won’t need cooling or lubrication systems – which in turn saves on energy consumption as well as maintenance expenses.

Low Maintenance Needed:

Canned motor pumps require little to no upkeep compared to traditional models, since they don’t need shaft seal replacement or other related maintenance.

This simplifies costs associated with repairs and downtime, improving overall reliability and productivity levels.

Compact Design:

Canned motor pumps feature a compact design, taking up less space than traditional models.

This makes them perfect for applications where space is at a premium, such as offshore oil rigs, submarines and aircraft.

Canned Motor Pumps for Enhanced Safety:

Canned motor pumps are engineered to enhance safety in hazardous environments by not having shaft seals that could leak fluid, thus reducing the risk of fires, explosions, and other accidents.


Canned motor pumps offer a high degree of customization, allowing you to tailor them according to your application needs.

You have the freedom to select materials of construction, flow rates, and head capacities so that the pump runs optimally at your facility.

Applications of Canned Motor Pumps:

Canned motor pumps can be used in a variety of applications, such as:

Chemical and Petrochemical Industries:

Canned motor pumps are ideal for handling aggressive liquids in chemical and petrochemical industries.

They can safely handle aggressive chemicals, such as acids, alkalis, and solvents without fear of leakage.

Nuclear Power Plants:

Canned motor pumps are essential in nuclear power plants to handle radioactive liquids and gases.

These units offer a high degree of safety and dependability, which is essential in such critical applications.

Oil and Gas Industry:

Canned motor pumps are utilized in the oil and gas industry to handle crude oil, natural gas, and refined petroleum products.

They can be utilized both offshore and onshore for drilling, production, and refining operations.

Pharmaceutical Industry:

Canned motor pumps are widely used in the pharmaceutical industry to handle sensitive fluids and chemicals such as vaccines, enzymes, and antibodies.

These pumps must meet stringent regulatory requirements while offering a high degree of safety and dependability.
