In the chemical process industry (CPI), industrial pumps are essential for the processing, storage and transfer of flowing materials. As a “rising star” among them, magnetic drive pumps are becoming increasingly popular. It is a seal-less centrifugal pump that uses magnetic technology to connect the motor and the pump and has been in operation for nearly seventy years.
In recent years, due to stricter requirements and new emission regulations in the chemical and petrochemical industries. It has stood out with its high efficiency, low maintenance and high safety. In this article, South Pump will give you an in-depth understanding of the definition of magnetic pumps, their advantages in chemical industry, and their applications.
What is a magnetic drive pump?
In today’s industrial society, many people use centrifugal pumps in their projects. Among them, magnetic pumps are a type of centrifugal pump. However, unlike centrifugal pumps, chemical magnetic pumps use magnets to form a seal between the motor and the impeller. Therefore, magnetic pumps do not require mechanical seals to achieve leakage and pollution-free. Within your project budget, mag-drive pumps are an ideal choice.
There are many kinds of materials for magnetic-drive (mag-drive) pumps, such as cast iron, stainless steel, alloys, etc. The motor and pump of the efficient magnetic pump are mainly connected by magnets. There is also a layer of isolation cover outside the magnet to ensure safety during use. In addition, magnetic pumps are divided into rotating shafts and fixed shafts. It is very flexible and can meet the transportation of many kinds of corrosive liquids, such as sulfuric acid, nitric acid, sodium hydroxide, sodium hypochlorite, etc.
4 Benefits of Magnetic Drive Pumps in Industrial Processes
It can be said that magnetic drive centrifugal pumps are an innovative solution. Sometimes magnetic pumps are even more economical than other types of centrifugal pumps. Magnetic drive pumps not only do not require mechanical seals, but also do not require sealed liquid tanks and cooling pipes. Magnetic pumps have the following five main advantages.
1.Leak-free without mechanical seals
The biggest innovation of magnetic pumps is that they can achieve no leakage without mechanical seals. Traditional centrifugal pumps mainly require various mechanical seals to prevent leakage. These seals are not only numerous in type, but also easy to wear. Especially when you use the pump to transfer corrosive liquids.
Therefore, magnetic drive pumps cancel the use of mechanical seals. Instead, they use magnetic force to connect the motor and the shaft. In addition, mag-drive pumps still use static containment to seal the fluid. This further ensures that the pump is leak-free and increases the safety of the operator.
2. Energy efficiency
In the “power world” of industry, magnetic drive pumps are “energy-saving heroes”! Traditional pumps are like “big energy consumers”. Mechanical seals and moving parts “pull” each other, friction generates heat, and a lot of energy is wasted.
On the other hand, lined-in magnetic driven pumps rely on the magical magnetic coupling technology to “transmit power through the air”. There is no need for direct contact drive, which keeps friction loss out. The power generated by the motor can be transmitted to the impeller in a nearly perfect state. It uses super high energy efficiency to “reduce the burden” for enterprises. So in the long run, the energy efficiency of using magnetic pumps is considerable.
3. Low maintenance cost
Magnetic drive pumps have significant advantages in equipment maintenance. Compared to traditional pumps. It’s cleverly designed. Few moving parts. The friction between them during operation is greatly reduced. Greatly reduces wear and tear.
This directly brings two major benefits: First, downtime is drastically reduced. Maintenance intervals can be extended. Companies don’t have to stop production lines frequently. Guaranteed the continuity of production.
Second, maintenance costs have plummeted. Traditional pumps often require replacement of seals and lubrication of bearings. Time consuming and expensive. Lined-in fluorine plastic self-priming magnetic driven pump save these troubles. It also reduces manpower investment. It also saves the cost of replacing parts. This allows companies to focus more energy and funds on improving productivity. Create greater benefits.
4. High durability
The magnetic drive centrifugal pump is like a reliable “industrial guard” with unique skills to protect the production line! On the one hand, it is exquisitely designed. The magnetic pump has few moving parts. Low operating wear. So it reduces downtime. Extends maintenance intervals. In addition, it also reduces maintenance costs. It eliminates the tedious operations such as frequent replacement of seals and bearing lubrication.
On the other hand, the sealless design of the magnetic drive pump eliminates common failure points. It is highly durable. Long service life. Greatly reduces the risk of unexpected downtime and expensive repairs.
Magnetic drive pump applications
1. Chemical industry
In the chemical industry, standard magnetic pumps are known as “safety guards”. In the face of corrosive, flammable and explosive chemicals, they can be safely transported by virtue of their design of corrosion-resistant materials such as stainless steel. They achieve fully sealed power transmission through magnetic coupling, eliminating the risk of leakage and damage, and are able to easily transport acids, alkalis, solvents, etc., making them the best choice.
2. Oil & Gas
In the oil and gas industry, durable magnetic pumps are the “hard core”. Faced with high pressure, high temperature, and high flow fluids. They have strong power and stable performance, and can be regarded as key equipment in all links from crude oil extraction to refining. Long-distance transportation is not a problem. And they can also prevent leakage, strictly abide by regulations, and ensure a stable supply of energy.
3.Construction and municipal industry
In the construction and municipal industries, engine magnetic pumps are the “heroes behind the scenes”. In the water supply and drainage of high-rise buildings, they deliver water to high places to ensure water supply for residents. In fire protection systems, they can quickly supply water in emergencies to protect life and property. The corrosion-resistant version can also safely handle industrial fluids and meets the latest standards.
