Which is better, pneumatic diaphragm pump or magnetic pump?

Pneumatic diaphragm pumps and magnetic pumps are often used in medical, pollution and chemical industries to treat waste, wastewater, fuel and other substances. But do you know their respective advantages? Today, I will tell you the respective advantages of pneumatic diaphragm pump and magnetic pump, which is convenient for you to choose.

Below is a list of contents

1. Advantages of pneumatic diaphragm pump

2. Advantages of magnetic pump

The advantages of pneumatic diaphragm pump are:

In the flammable and explosive environment, the pneumatic pump is reliable and low-cost, such as the transportation of fuel, gunpowder and explosives, because: first, it is impossible to produce sparks after grounding; Second, no heat is generated in the work, and the machine will not overheat; Third, the fluid will not overheat, because the diaphragm pump has the least stirring to the fluid.

In the bad places of the construction site, such as the wastewater discharge of construction site and industrial and mining, due to the large number of impurities and complex components in the sewage, the pipeline is easy to be blocked, so the load of the electric pump is too high, and the motor is vulnerable to heating.

Diaphragm pump can be used to transport fluids with unstable chemical properties, such as photosensitive materials, flocculant, etc.

Diaphragm pump in the treatment of hazardous and corrosive materials, the diaphragm pump can completely separate the materials from the outside world.

The diaphragm pump or some tests ensure that there are no impurities contaminating the raw materials. In addition, the diaphragm pump is small, easy to move, does not need foundation, covers a very small area, and is easy and economical to install.

Advantages of magnetic pump

Since the sliding bearing of the magnetic pump is lubricated with the transmitted medium, different materials should be selected to make the bearing according to different media and service conditions.

The advantages of magnetic driven centrifugal pump include no leakage at all, large intermittence between inner and outer rotors, no more than 8mm in thickness when using non-metallic isolation sleeve, no more than 5mm in thickness when using metal isolation sleeve, large wall thickness of isolation sleeve, less possibility of wear through of isolation sleeve, large gap between isolation sleeve and inner and outer magnetic rotors, and reliable operation of magnetic centrifugal pump, The possibility of wear of internal magnetic rotor and isolation sleeve caused by shaft seal wear is small. The isolation sleeve is easy to disassemble, can be replaced on site and easy to maintain. It can be applied to SiC bearing with good wear resistance and long service life. The speed of the pump is not limited by the motor. It can be different from the motor speed. In addition, the magnetic centrifugal pump also has the following advantages:

1. Because the transmission shaft of the magnetic centrifugal pump does not need to penetrate into the pump shell, but uses the magnetic field to pass through the magnetic field and the thin-walled transmission torque of the isolation sleeve to drive the internal magnetic rotor, so it fundamentally eliminates the leakage channel of the shaft seal and realizes complete sealing.

2. The magnetic drive pump has the function of overload protection when transmitting power.

3. The magnetic material and magnetic circuit design of magnetic pump have high requirements, but the technical requirements of other parts are not high.

4. The maintenance and overhaul workload of magnetic drive pump is small.

Taicang magnetic pump Co., Ltd. was born in 1979. It cooperated with Shanghai Chemical Design Institute to form a unique core research project with magnetic drive pump, and achieved great success. It has become the first company in China to comprehensively design and produce magnetic drive pump. Today, Taicang magnetic pump Co., Ltd. has become a leading manufacturer of magnetic drive pumps in China, with many patents and 12 utility model patents.
