Canned Motor Pump
The stator is canned is canned in the air gap, confining the liquid in the rotor chamber. The pump liquid circulates through the rotor chamber, cooling the motor, and lubricating the slide bearing that support the rotor. The casting of the chamber forms a seal less enclosure that confines the liquid without any precision sealing.
Features:
- Sealless Design: The most distinctive feature of CMPs is their sealless design. The motor and pump impeller are enclosed within a single, hermetically sealed casing, eliminating the need for traditional shaft seals. This prevents leakage and ensures containment of hazardous fluids.
- High Reliability: The absence of mechanical seals significantly reduces the risk of failure and downtime. CMPs are known for their long service life and minimal maintenance requirements.
- Energy Efficiency: CMPs are designed to operate efficiently, reducing energy consumption and operating costs.
- Compact Design: Their compact footprint makes them suitable for installation in confined spaces.
- Quiet Operation: CMPs are relatively quiet compared to traditional pumps, reducing noise pollution in the workplace.
- Wide Range of Applications: CMPs can handle a wide range of fluids, including those that are toxic, corrosive, flammable, or radioactive.
Advantages:
- Zero Leakage: Eliminates the risk of fluid leaks, protecting the environment and personnel.
- Reduced Maintenance: Fewer maintenance requirements due to the absence of mechanical seals.
- Increased Reliability: Longer service life and fewer breakdowns.
- Increased Reliability: Longer service life and fewer breakdowns.
- Energy Efficiency: Lower energy consumption.
How CMPs Work ::
- Fluid Entry: The fluid enters the pump casing through an inlet port.
- Impeller Rotation: The motor drives the impeller, which imparts kinetic energy to the fluid.
- Motor Cooling: The fluid flowing through the pump casing also serves to cool the motor, ensuring efficient operation.
- Fluid Discharge: The fluid is accelerated by the impeller and discharged through the outlet port.
