Design Features of Canned Retro Pumps [FISB-000T2]
Our Canned Retro Pumps [FISB-000T2] replace your existing mechanical seal and air cooled motor. It couples directly to your existing pump case, allowing you to keep your existing pump and eliminate the problematic mechanical seal.
Key Benefits:
- Keep your existing pump installation
- No mechanical seal means no leakage
- Inherently safe
- Double layer pressure boundary containment
- Self-lubricated bearings – no external lubrication system needed
- Eliminates pump and motor alignment – common shaft
- Thrust bearing provides reliability during upset pump conditions
- Low noise

Canned Motor Pump FAQs
What is a canned motor pump?
A canned motor pump is a type of centrifugal pump where the pump and motor are integrated into a single, sealed unit. The pump and motor combination are leak-free, making them suitable for pumping hazardous liquids as they will not leak into the atmosphere.
What is a canned motor pump used for?
Our canned motor pumps are ideal for applications that require the highest reliability, safety, and performance, as our pumps are leak-free and low maintenance. They are used in a variety of industries—such as petrochemical, chemical refinement and processing, hydrogen and clean energy, refrigeration, renewables, and nuclear—to move large amounts of fluid.
Why choose a canned motor pump over other options?
Canned motor pumps are preferred over mechanically sealed pumps and magnetic drive pumps for a number of reasons. Lack of seals eliminates failures and safety issues that seals can cause. They are are also low maintenance and reduce noise levels. They also weigh less than other pumps, eliminating the need for a foundation, and eliminate problematic emissions inspections and reporting associated with other pump types.
How is the seal eliminated in these pumps?
Due to the laws of physics, higher-pressure fluids want to move to lower-pressure areas. Because traditional pumps must couple to a driver (motor or turbine), the shaft needs to exit the pump pressure boundary (pump case). This means the high-pressure fluid created by the rotating pump wants to leak into the atmosphere along the shaft penetration. This is stopped in traditional pumps by using gland packing or a mechanical seal. CMPs and BCPs use a different approach by using a common shaft for the pump and motor and containing it all in a pressure boundary. This eliminates the pressure differential across the rotating seal and the driving force for the fluid to leak.
What type of material(s) are canned motors pumps made from?
Canned motor pumps are typically made from type 304 stainless steel for wetted components, with the stator and rotor cans constructed from Hastelloy C276 for its high corrosion resistance and efficiency. Gaskets are usually made of PTFE or spiral-wound stainless steel, depending on temperature and pressure conditions. Bearings are typically made from carbon graphite or silicon carbide, chosen based on application requirements.
Are these pumps environmentally friendly?
Our CMPs and BCPs are inherently safe and environmentally friendly. Because they are sealless, the danger of a fluid leak is eliminated, preventing contamination to the environment.
How long do these pumps lasts?
Our CMPs and BCPs can last up to 30 years, but typically last 10 to 15 years. The lifespan is dependent upon fluid properties and operating conditions.
