Centrifugal Magnetic Drive Pumps

Centrifugal Magnetic drive pumps are commonly used in situations where leakage of the pumped liquid poses a significant risk, such as with aggressive or risky liquids, exotic materials, acids, alkalis, corrosives, pollutants, and toxins. They are also used for ultra-pure liquids and liquids that are difficult to seal. Sealed pumps used for these services may leak over time or require complex, expensive double seals to prevent hazardous/challenging liquids from escaping into the atmosphere, posing safety risks, downtime, and increased maintenance requirements. Another important application for Centrifugal magnetic drive pumps is for difficult liquids; for example, certain liquids can crystallise on seal faces, causing seal failures. To prevent this, a permanent flush system should be installed to the seal. However, this can raise the cost of maintenance, seal flushing liquids, and energy consumption. A Centrifugal magnetic drive pump is a better solution for these difficult services.


Because there is no direct connection between the electric motor shaft and the impeller in centrifugal magnetic drive pumps, no seal is required. Unless the pump casing is broken, there is no risk of leakage. Seals are a common cause of pump trips and unplanned shutdowns. The removal of seals significantly improves pump performance, reliability, and availability. The risk of leakage is eliminated, allowing liquids to be pumped without spillage. By removing the seals, you eliminate the associated friction loss, wear, costs, and noise. This allows for the complete separation of liquid from the pump drive and improved motor power transfer to the pump. Because the pump chamber is completely separated from the electric motor by a large air gap, there is virtually no heat transfer from the electric motor; this acts as an effective barrier between the two. Any shocks or spike torques will be softened by the magnetic coupling. Even in extreme circumstances, it will serve as a fuse. Magnetic couplings can be temporarily broken if the pump’s load is too great. In practice, this means that the centrifugal magnetic drive pump will not overheat and become damaged.

PP Centrifugal Magnetic Drive Pumps

Centrifugal Magnetic drive pumps are available in a wide range of metals and materials, both metallic and nonmetallic. Pumps with polymer linings are also used because they are more corrosion resistant. Polypropylene (PP), Polytetrafluoroethylene (PTFE), perfluoroalkoxy alkanes (PFA), and polyvinylidene fluoride are polymer coating options (PVDF). These lined or non-metallic options are typically used for normal temperatures, typically below 90°C as a rough guideline. For even higher temperatures, metallic magnetic drive pumps have been used.
