What Is Magnetic Drive Pump? A magnetic drive pump contains two magnets: the internal magnet and the drive magnet, which are both located inside the pump chamber. For short, these pumps are also known as mag drive pumps. They are widely used in the chemical sector due to their sturdy design, which makes them perfect for handling highly corrosive chemicals. A magnetic drive pump features a hermetically sealed chamber and a seal less design, making it airtight and less prone to leak liquid or vapor, in contrast to a pump shaft that runs through the outer casing. This will be extremely advantageous to businesses that pump pricey chemical goods into manufacturing environments that they cannot afford to risk leaking. Additionally, there are numerous variants of magnetic drive pumps, such as centrifugal, regenerative turbine, horizontal pumps, vane, and OEM that combine the advantages of a mag drive pump with their operating principles.
How Operate Magnetic Drive Pumps? Two magnets work together in tandem to push liquid through magnetic drive pumps; The first magnet, also known as the “external” or “drive” magnet, is fastened to the motor shaft either with grub screws or special adhesive. The pump houses the second magnet, which is encased in either metal or high-grade thermoplastic. As power is provided to the engine, the engine shaft revolution makes the joined outer magnet turn. The internal magnet rotates in tandem with the external driving magnet because of the different polarities of the magnets. The pump’s impeller is connected to this internal magnet, which then pumps the liquid.
Attractive Drive Pump Correlation As there is no actual association between the engine shaft and impeller gathering, the cycle liquid is held inside the pump head, in this way ensuring release-free activity. In contrast, unlike a conventional centrifugal pump, the industrial centrifugal pump has an impeller that is directly coupled to the motor shaft, which is sealed mechanically to prevent process fluid from entering the motor. While the horizontal pumps are very similar in many ways, there are some important differences to keep in mind when selecting one. The method by which the motors of Magnetically Driven Centrifugal Pump and Industrial Centrifugal Pump transmit power and speed to the impeller is the primary distinction between the two models. The CTM is driven by magnetism, which means that the impeller is attached to a magnetic coupling and the motor shaft is connected to it. Because the impeller/magnet and drive magnet assemblies’ magnets have different polarities, the pump volute’s impeller magnet assembly is compelled to rotate when the motor shaft turns.
Differences In Design Both the CTI Pump and the Mag Drive Pump are Close-Coupled Centrifugal Pumps that can be provided with either closed or semi-open impellers. On the other hand, the Industrial Centrifugal Pump is also offered with an open impeller that can handle solids as small as 6 mm. Both of these reduced pumps are great for applications requiring high mechanical and consumption opposition, as the CTM is made from Glass Fiber supported Polypropylene or PVDF, and the CTI is produced from Glass impacted Hardened Steel. The magnetically driven centrifugal pumps additionally have the additional advantage of all wetted parts being made from non-metallic infusion-formed thermoplastics, which reinforces the incredible consumption obstruction of the pump. The CTI and CTM, as well as other Centrifugal or Horizontal Pumps, are made with dependable technology. Because they have fewer parts, they require less maintenance and have shorter downtimes.
The Mag Drive also offers the benefit of being a seal less pump, in contrast to the CTI, which can be supplied with a choice of mechanical seals. Additional alternatives include flushed seals, which are advised for applications involving fluids that are sticky or abrasive, and lubricated seals, which are appropriate for applications where there is a risk of dry running or the fluids hardening within the pump. The advantage of the CTM being seal less implies that it tends to be utilized inside enterprises that need to lessen the gamble of unsafe liquids spilling out of the pump, like atomic and compound businesses. This also means that the pump’s design doesn’t need to use glues or resins, making the Mag Drive Pump work better and safer at higher temperatures.
Magnetic Drive Pump Advantages/Benefits • Increased Productivity A pump without a mechanical seal eliminates a potential leak point, allowing for the pumping of hazardous fluids without fear of spillage. The absence of mechanical seals has financial benefits as well, including reduced maintenance costs and downtime as well as increased productivity. • Safety First And Avoiding Fugitive Emissions The fluids being pumped frequently pose a risk to employees working on or near pumps and pumping systems, in addition to posing a threat to the environment. Numerous of these fluids need to be governed by rules for contingency plans. Magnetic drive pumps stop leaks, and since there is no leak, employees are safe from chemicals that could harm them (employees). Mag-drive pumps also stop fugitive emissions such as volatile organic compounds (VOCs) and volatile hazardous air pollutants (VHAPs), enabling companies to stay in compliance with local, state, and federal health and safety requirements while avoiding exorbitant fines.
Magnetic Drive Pump Disadvantages • Solids In applications including even a little level of solids, a mag-drive siphon is not a reasonable arrangement. Mag-drive pumps should only operate with clear liquids devoid of suspended solids. • Cost Mechanically sealed pumps typically cost less than mag-drive pumps. However, taking into account the aforementioned advantages and lower costs of maintenance, the additional cost may be offset. The drawn-out monetary benefits and all-out cost of possession ought to be thought about while picking this pump plan. Keep in mind that a magnetic drive pump is the best choice because it does not have a seal, so there is no risk of leaks in applications where the liquid is toxic, expensive, or highly corrosive. The majority of metallurgies and materials, both metallic and non-metallic, are suitable for magnetic drive pumps. These pumps are entirely dependable, require extremely low support thanks to their interesting plan, and are intended to offer difficulty-free execution over numerous long stretches of administration life.
