Sealless Canned Motor Pumps – We are Sealless Canned Motor Pumps manufacturer in Mumbai.
Canned motor pumps are characterised by a compact, integrated unit without mechanical shaft seal and therefore are also called Sealless pumps. The motor and pump form a single unit with the rotor and impeller mounted on a common shaft with no coupling joints in between. The rotor of single and multistage canned motor pumps are guided by two identical self-lubricated slide bearings. The stator of the drive motor is separated from the rotor by using a thin liner sheet called as can.
The rotor cavity along with the hydraulic section of the pump creates a combined cavity which must be filled with the pumping liquid before starting the pump. The heat loss from the motor is carried off by a partial flow of pumping liquid between the rotor and stator, at the same time, pumping fluid itself lubricates both the slide bearings in the rotor cavity. Both the stator and rotor can which is a hermetically sealed component and the motor housing acts as a safety containment. Due to this, canned motor pumps always ensure a higher safety levels especially while pumping dangerous, explosive, toxic and valuable fluids and maintains the safety standards of the plant.
The high reliability of these pumps makes them suitable for pumping of toxic, hazardous liquids, high temperature, and high pressure services in nuclear power plant, Lithium Bromide circulation in refrigeration plant, Ammonia transfer in fertilizer plants, refineries, chemical and pharmaceutical industries and other process industries for handling toxic, hazardous or expensive fluids.
Canned Motor Pump is a centrifugal pump with pump and hermetically sealed electric motor mounted on single shaft thus eliminating the requirement of mechanical seal or other sealing device. Entire rotating assembly is immersed in the liquid, and motor stator and rotor are isolated from the pumped liquid with corrosion resistant, non-magnetic liner and sleeve. A part of the pumped liquid is by-passed through the motor, for cooling of motor and lubricating the bearing.

2/4 pole, 3 phase, 415V/480V, 50 Hz/60 Hz, Class of insulation F, H or C. Flame-proof and explosion proof construction with built-in safety devices available.
The FLOWDYNE Sealless is a compact centrifugal canned motor pump with integrated motor that covers high-pressure and high-temperature applications.
Directly integrating the canned motor into the centrifugal pump does not only ensure environmental protection, but also safety at the plant. All parts of the pump are also designed for easy and fast maintenance. Therefore, you can minimize unproductive down times.
Compared to solenoid driven pumps, the FLOWDYNE canned motor pump features considerably better high-pressure properties. Therefore, it is ideally suited for transfer and circulation tasks with critical or hazardous fluids.
Since the fluids lubricate the sliding parts, no additional lubrication is required. This gives the pumps a high degree of serviceability.
Due to the integrated structure of the centrifugal canned motor pump, it only needs very little space and is ideal for applications in which a small footprint is required.
The pump is quiet and has low vibration. It is extremely weather-resistant and has good dust protection.
The pump has only low maintenance costs due to the relatively low number of components and the real-time monitoring of the bearing wear.
