About MDP 170 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 two magnetic assemblies, hermetically seals the hydraulic section from themotor, ensuring no fluid leakage.

Ultimate Corrosion Resistance

Crafted from premium Polypropylene (PP), the MDP 170 magnetic drive pump resists attack from harsh acids, alkalis, and corrosive solutions, making it ideal for the toughest chemical processes. With stainless steel 316 shaft and carbon/ceramic bearings, it ensures longevity and consistent performance even under challenging conditions.

Leakage-Proof Safety and Efficiency

Thanks to its magnetic drive technology and seal-less design, the MDP 170 prevents fluid leakage, ensuring environmental safety and reducing maintenance needs. The closed impeller maximizes hydraulic efficiency, while IP55 enclosure protection and Class F insulation guarantee reliability in demanding industrial settings.

FAQ's of MDP 170 PP Seal-less Magnetic Drive Pumps:

Q: How does the seal-less magnetic drive design benefit chemical transfer applications?

A: The seal-less magnetic drive in the MDP 170 eliminates traditional mechanical seals, making the pump completely leak-proof. This design is especially valuable for transferring hazardous or corrosive liquids, as it ensures operational safety, reduces maintenance, and prevents environmental contamination.

Q: What types of fluids can the MDP 170 PP Magnetic Drive Pump handle effectively?

A: This pump is engineered to handle acids, alkalis, corrosive chemicals, and viscous fluids up to 200 cP. Its Polypropylene construction and high-quality shaft and bearings enable it to safely transfer a wide range of aggressive liquids common in process industries.

Q: Where can the MDP 170 pump be installed and what is the recommended mounting position?

A: The MDP 170 pump is designed for base plate mounting in a horizontal position, making it suitable for installation in industrial chemical plants, laboratories, and other process facilities. Its IP55 enclosure and robust construction support indoor and semi-outdoor locations within India.

Q: What is the typical process for starting up the MDP 170 magnetic drive pump?

A: The pump utilizes a flooded suction setup and does not require self-priming. Ensure the suction line is fully flooded with liquid, connect to a suitable power supply (220V/380V, 50/60 Hz), and start using a manual or DOL starter as per the control system provided. The pump will automatically deliver up to 170 L/min flow at a maximum head of 14 meters.

Q: When is it recommended to use a magnetic drive pump over a conventional centrifugal pump?

A: Magnetic drive pumps like the MDP 170 are recommended when there is a critical need for leak-free operation, such as handling hazardous, corrosive, or toxic chemicals. Their seal-less construction prevents product loss and enhances safety, which is essential in chemical processing and transfer.

Q: How does the motor cooling and insulation system contribute to reliable operation?

A: The Totally Enclosed Fan Cooled (TEFC) motor provides efficient cooling and dust protection, while Class F insulation ensures durability at high temperatures. Combined with the IP55 enclosure, these features extend motor life and assure reliable operation in challenging industrial settings.
