Manufacturing, construction, agriculture, oil & gas, and other sectors all use magnetic drive pumps. They are superior to traditional pumps, but they also have some drawbacks. For instance, a magnetic drive pump can be useful for pumping water and other liquids even though it may not be the best option for handling solids with centrifugal pump.
Pumps with magnetic drives are made to transmit torque and power from a motor to a fluid. Despite their potential for success, they have a number of drawbacks.
First, when a magnetic drive's torque exceeds its capacity, it may decouple. The breakaway torque has the potential to stop the impeller from rotating. This is a bad circumstance. In fact, a pump may become permanently demagnetized if it is run at high speeds for an extended period of time.
Second, the liquid's temperature can affect magnetic drives. Frictional losses may be substantial if the liquid has a high viscosity.
Thirdly, the wear rate of the bearings may increase if the magnetic drive is used in an aggressive or corrosive medium. Other components of the pump may also sustain damage.
A patented magnetic drive system is used in self-priming magnetic drive pumps, a type of centrifugal pump that offers quick and precise priming. These pumps come in a wide range of styles and configurations. They are perfect for a variety of uses. These pumps can be used to pump water, solvents, and chemicals, depending on the particular requirements of the customer.
These pumps have the ability to self-prime with valve, which eliminates the need for a bottom valve and is one of their benefits. They are therefore simple to install and maintain. Making sure the pump is installed as near to the water's surface as possible is crucial for optimum performance. Furthermore, it is advised that the suction pipe be horizontal.
Applications for magnetic drive pumps with Crystallizer include the handling of toxic substances, corrosive liquids, and wastewater and sewage. They have a number of benefits over other kinds of pumps. They do, however, have drawbacks. The limitations of magnetic drive pumps should be understood by those who are thinking about using them.
The type of solids in the pumped liquid will determine how well the solids can be handled. The ability of the pump to handle solids increases with the percentage of solids in the pumped liquid. In general, pumps can function with up to 5% solids. To avoid particles from forming, solids over this amount may require a filter or strainer.
Consider the type of bearing materials a pump uses if you want to be sure of its ability to handle solids. In contrast to weaker bearing materials, hard bearing materials are more likely to result in issues.
In situations where it is challenging to maintain the pump's efficiency or to seal the pumped medium, magnetic drive pumps can be helpful. They can also be used to handle poisonous or incredibly pure liquids.
Magnetic drive pumps, however, are not recommended for high-solids applications. The performance of the pump can be hampered by solids, which can also result in failures. Therefore, it is crucial to properly flush the pump. Leakage is also a possibility, which could result in maintenance issues and downtime.
Thankfully, there are plenty of contemporary options that provide increased hydraulic efficiency and longer usable lifespan. For instance, MX series pumps have a corrosion-resistant design and are self-radiating. They can withstand challenging operating conditions because of this.
The SMX-F, a horizontal self-priming magnetic drive pump, is an additional choice. Fluororesin and materials resistant to corrosion are used in its production. It has a high specific gravity range.

Pumps with magnetic drives, also known as "mag drive pumps," work by magnetic attraction. Compared to mechanical seal pumps, they contain fewer moving parts. These are typically used in difficult-to-seal applications, such as those for hazardous materials. This makes maintaining these pumps less expensive, as well as enabling them to operate more effectively and with less downtime.
They do have limitations, though. For instance, they are only capable of handling 5% solids. The chemical being pumped through the plastic lining has the ability to diffuse, which allows it to accumulate in the passages. The bearings, for example, are one of the parts of the pump that are subject to wear with Separator.
This occasionally can result in failures and downtime. Many facilities are switching to seal-less pumps as a result of these factors.
