What Is a Canned Motor Pump and What Are Its Uses?

A canned motor pump is a type of pump that uses an electrically powered motor to drive a pump mechanism. The motor and pump are enclosed in a sealed canister, or "can," which help to protect the pump from the environment and vice versa.

This type of pump is often used in hazardous or difficult-to-reach environments, such as in chemical plants or oil refineries because it minimizes the risk of leaks. Canned motor pumps can also be used in food and beverage processing, as well as in medical and pharmaceutical applications.

While canned motor pumps offer many advantages, they can also be more expensive than other types of pumps. Additionally, because they are sealed units, they may be more difficult to repair or replace if they break down.

How does a canned motor pump work?

A canned motor pump is a type of hermetically sealed pump that uses an electric motor to drive the pumping action. The pump and motor are housed within a canister, or can, which is filled with a dielectric fluid. This fluid provides both cooling and insulation for the electric components, allowing the pump to run continuously without overheating.

Canned motor pumps are used in a variety of applications where it is important to maintain a sealed environment, such as in chemical processing or food and beverage production. These pumps are also often used in hazardous environments where flammable liquids need to be transferred, as there is no risk of sparks from the electric motor igniting the surrounding atmosphere.

Canned motor pumps are typically centrifugal pumps, meaning they use an impeller to push fluid through the pump. The electric motor turns the impeller, which draws fluid in from the pump’s inlet and then pushes it out through the outlet. The canister surrounding the pump and motor is filled with a dielectric fluid, which helps to cool the electric components and keep them from overheating. This type of hermetic seal is necessary to prevent any of the flammable or hazardous liquids being pumped from leaking out and potentially causing harm.

Canned motor pumps are a reliable and efficient way to move liquids in a variety of applications. Their hermetic design makes them ideal for use in hazardous or flammable environments, and their centrifugal design means they can handle a wide range of liquid viscosities. With proper maintenance, canned motor pumps can provide years of trouble-free operation.

Advantages of using a canned motor pump

Canned motor pumps have numerous advantages over other pumps. Here are a few important points to be aware of:

1. Canned motor pumps are hermetically sealed, meaning that there is no need for seals or packing. This results in a much more reliable pump that is less likely to leak.
2. Canned motor pumps are self-lubricating, which reduces maintenance costs and downtime.
3. Canned motor pumps are often smaller and lighter than other types of pumps, making them easier to install and operate.
4. Canned motor pumps typically have a longer life span than other types of pumps, due to their simplified design and lack of moving parts.
5. Canned motor pumps are often more energy efficient than other types of pumps, due to their higher efficiency motors.
6. Canned motor pumps can be used in a wide variety of applications, including high-pressure and high-temperature applications
7. Canned motor pumps are available in a variety of materials, such as stainless steel, Hastelloy, and titanium, making them suitable for use in aggressive environments.
8. Canned motor pumps are often used in hazardous or flammable liquids applications due to their hermetic seal and lack of external seals or packing. This makes them much safer to use than other types of pumps.
9. Canned motor pumps can be customized to meet the specific needs of your application.
10. Canned motor pumps are backed by a wide variety of Canned motor pump manufacturers, making it easy to find a pump that meets your specific needs.
