About MDP 85 PP Seal-less Magnetic Drive Pumps

Denwell seal-less magnetic drive centrifugal pump operates by connecting anexternal magnet directly to the motor shaft, which then conveys torque toan internal magnet. This setup generates a magnetic field that allows theimpeller to rotate and move the fluid without any physical contactbetween the moving parts. The rear casing, situated between the twomagnetic assemblies, hermetically seals the hydraulic section from themotor, ensuring no fluid leakage.

Outstanding Chemical Compatibility

Constructed from premium polypropylene, the MDP 85 PP pump offers excellent resistance to aggressive chemicals. This makes it ideal for transferring acids, alkalies, and corrosive liquids in various environments, ensuring durability and long service life even in demanding applications.

Maintenance-Free Seal-less Operation

With its seal-less magnetic drive mechanism, this pump eliminates the need for mechanical seals, preventing leaks and reducing maintenance requirements. The innovative design enhances operational safety and reliability, making it a preferred solution for handling hazardous fluids.

Reliable Performance and Versatility

Operating at speeds up to 2900 RPM, this pump delivers consistent flow rates and head pressure. Its adaptable motor supports both 220V and 380V, fitting varied industrial setups. Threaded and flanged connections, combined with a robust base mounting, facilitate easy installation and integration into different process streams.

FAQ's of MDP 85 PP Seal-less Magnetic Drive Pumps:

Q: How does the seal-less magnetic drive design improve safety and maintenance of the MDP 85 PP pump?

A: The seal-less magnetic drive eliminates the need for mechanical seals, which are prone to wear and leakage. This design ensures a leak-proof operation and significantly reduces routine maintenance, making the pump a safer and more economical choice for transferring hazardous chemicals.

Q: What types of fluids can be handled by the MDP 85 PP pump?

A: This pump is ideal for transferring a wide variety of chemicals such as acids, alkalies, and corrosive liquids, thanks to its polypropylene construction and corrosion-resistant features. Its design also supports particle transfer up to a maximum size of 2 mm.

Q: When is it appropriate to use this pump for chemical processing applications?

A: The MDP 85 PP pump should be used whenever there is a need to move corrosive or hazardous fluids safely and reliably. Its robust construction and magnetic drive make it suitable for challenging environments in chemical processing, laboratories, and water treatment facilities.

Q: Where can the MDP 85 PP pump be installed?

A: The pump is suited for indoor or moderately protected environments, owing to its IP55 rating and TEFC cooling method. It can be base mounted with threaded or flanged connections, allowing for flexible installation in diverse industrial setups throughout India.

Q: What process benefits does the MDP 85 PP pump offer in laboratory and industrial operations?

A: Its maintenance-free, leak-proof design and corrosion resistance reduce downtime and hazard risks, while its reliable performance ensures efficient chemical transfer. The pump's manual or optional automatic controls help streamline operations for varied industrial and laboratory needs.

Q: How can users optimize the usage of this pump for acidic and alkaline fluid transfer?

A: To optimize pump performance, ensure that the ambient temperature does not exceed 40C, and the working temperature of the fluid stays within -20C to +85C. Regularly monitor connection integrity and ensure the system uses flooded suction to facilitate maximum flow and reliability.
