MDFY Magnetic Submerged Pump: Types and Characteristics

MDFY magnetic submerged pumps are widely used in chemical, pharmaceutical, and other industries that require the safe and efficient handling of corrosive and hazardous fluids. In this article, we will discuss the different types of MDFY pumps available and highlight some of their key characteristics.

Classification Of MDFY Magnetic Submerged Pump

There are several types of MDFY pumps available in the market, including:

Horizontal type

This type of pump is designed with a horizontal shaft and is suitable for handling fluids with large volumes.

Vertical type

This type of pump is designed with a vertical shaft and is suitable for handling fluids with smaller volumes.

Single-stage type

This type of pump has only one impeller and is suitable for handling fluids with low head requirements.

Multistage type

This type of pump has multiple impellers and is suitable for handling fluids with high head requirements.

Immersion type

This type of pump is designed to be fully submerged in the fluid being pumped.

Characteristics Of MDFY Magnetic Submerged Pump

Some of the key characteristics of MDFY pumps include:

Magnetic drive

The MDFY pump uses a magnetic coupling to transmit power to the impeller, eliminating the need for a mechanical seal.

Corrosion resistance

MDFY pumps are made of materials such as fluoroplastics and stainless steel, which provide excellent resistance to corrosion and other forms of chemical attack.

Submerged design

The MDFY pump is designed to be fully submerged in the fluid being pumped, providing increased safety and reducing the risk of leaks.

High efficiency

MDFY pumps are designed to operate at high efficiency, resulting in lower energy consumption and reduced operating costs.

Low noise

The design of the MDFY pump results in low noise levels during operation, making it suitable for use in noise-sensitive environments.

Easy maintenance

The MDFY pump is designed with easy-to-replace components, making maintenance quick and easy.

Conclusion

The MDFY magnetic submerged pump is an essential component in industries that require the safe and efficient handling of corrosive and hazardous fluids. By understanding the different types of pumps available and the key characteristics of each type, operators can select the right pump for their specific needs. The magnetic drive, corrosion resistance, submerged design, high efficiency, low noise, and easy maintenance of the MDFY pump make it an excellent choice for a wide range of applications.

Application Of Magnetic Submerged Pump

It is widely used in the transportation of volatile, flammable, explosive, toxic, harmful and other high-risk media in the production process of petroleum, chemical industry, coal chemical, alkali making, smelting, rare earth, pesticide, dye, medicine, scientific research institutions, and national defense industry.

Performance range	design pressure 1.6-5.0Mpa
Flow rate	1.8-400m3/h
Head	15-125m
Power	1.5-280kw
Applicable temperature	-20～350℃

Attention: Transporting media with a specific gravity greater than 1.3mg/cm3 should be stated when ordering; dry running is prohibited; transporting media containing particles or crystals is prohibited.

MDFY non-leakage magnetic drive submerged pump is a new type of high-efficiency and energy-saving non-leakage submerged centrifugal pump designed in accordance with national standards;
The material of the pump body, inner rotor, pump cover, impeller, isolating sleeve and pump shaft and other wetted parts can be made of 304, 316, 316L, 904, TA2, HC276 and other materials;
The pump body and pump cover adopt CFD computer fluid mechanics design hydraulic components for modular design and precision casting. They should be able to withstand the erosion of high-speed and high-pressure liquid, and be able to withstand the effects of instantaneous thermal shock, have high cavitation resistance, and have precise dimensions. The flow channel is smooth and clean to ensure the corrosion resistance and pressure resistance of the pump;
The impeller also uses CFD computer fluid mechanics to design hydraulic components for modular design and precision casting to ensure reliable torque transmission. Its closed structure, optimized flow channel design, high efficiency and low NPSHR value ensure the stability of pump flow and head. Sex
The isolation sleeve is made of 316L, TA2, HC276 and other materials and low-vortex spacer design. The isolation sleeve is in a sinusoidal alternating magnetic field and induces eddy currents in the cross section perpendicular to the direction of the magnetic force and converts them into heat. The isolation sleeve can be made of high-resistivity, high-strength non-metallic materials, which has a very obvious effect in reducing eddy currents, eliminating all excess heat and reducing energy consumption; it has high rupture pressure and high safety factor, and the pump The cavity is completely isolated from the outside, so that the pump chamber is completely sealed, and there is no leakage during the conveying process.
The moving ring, bushing and sliding bearing adopt high wear-resistant and temperature-resistant crystalline silicon carbide, tungsten carbide and other materials.
