Common corrosion resistant pumps include fluoroplastic anti-corrosion pumps and stainless steel anti-corrosion pumps, as well as common engineering plastics and PPcorrosion resistant pumps. Reasonable selection of corrosion resistant pump can improve the service life of anti-corrosion chemical pump.
Corrosion resistant pump selection requirements:
1. Make the type and performance of the selected corrosion-resistant chemical pump meet the requirements of process parameters such as flow, head, pressure, temperature, NPSH, and suction.
2. Correctly calculate the investment cost of purchasing corrosion resistant pump.
3. Must meet the requirements of medium characteristics:
a. For pumps that transport precious media, shaft seals are reliable or leak-free pumps, such as magnetic drive pumps (no shaft seals, isolated magnetic indirect drive);
b. For pumps that transport corrosive media, the convection parts are required to use corrosion-resistant materials such as fluoroplastic corrosion resistant pump;
c. For pumps that transport solid particulate media, the convection parts should be made of wear-resistant materials, and the shaft seal should be flushed with cleaning fluid if necessary.
4. The machinery requires high reliability, low noise and low vibration.
Use and maintenance of corrosion resistant pump:
1. Check whether the connection between the pump and the pipeline is loose. Turn the pump by hand to check that the pump is flexible, then check the motor rotation.
2. Add the bearing lubricating oil to the suspension, and observe that the oil level should be between the two levels of the oil standard.
3. Unscrew the water diversion plug of the pump body and fill the water diversion.
4. Close the gate valve, outlet pressure gauge and inlet vacuum gauge.
5. Start the motor. When the corrosion resistant pump is in normal operation, the working outlet pressure gauge and inlet vacuum gauge should gradually open the gate valve after showing proper pressure, and check the motor load.
6. Try to control the flow and head of the pump within the range indicated on the pump sign, and keep the pump running for a long time near the high-efficiency point to achieve greater energy-saving effect.
7. During the operation of the corrosion resistant pump, the bearing heating shall not exceed the ambient temperature of 35 degrees, and the higher temperature shall not exceed 80 degrees.
8. If the pump finds abnormal sound, stop immediately to check the cause.
9. When the pump is stopped, first close the gate valve and pressure gauge, and then stop the motor.
10. The corrosion resistant pump should change the lubricating oil for 100 hours in the first month of operation. Change the oil every 500 hours.
11. Regularly adjust the packing gland to keep the leakage in the packing room normal.
12. When the pump is used in cold winter, after parking, the drain plug at the lower part of the pump body must be unscrewed to remove water and prevent frost cracking.
13. When the corrosion resistant pump is stopped for a long time, the pump must be disassembled, the water should be wiped dry, the rotating parts and joints should be greased and stored properly.

First, the conveying medium is different: we all know that chemical centrifugal pumps are used in the chemical industry, mainly used to convey chemical raw materials with various liquid media such as acid, alkali, corrosiveness and toxicity. The ordinary centrifugal pump can only be used to transport some non-corrosive, acid-alkaline liquid media, such as: clean water, sewage, etc.
Second, the material is different: in the material of the pump, chemical centrifugal pumps are generally made of materials that can resist corrosion, acid and alkali, and the metal is stainless steel, 304, 316, 316L, etc. Non-metal ones are lined with rubber, fluorine and so on. This is mainly to play the role of anti-corrosion. Ordinary centrifugal pumps do not have so many requirements in terms of materials. We must all know that water is not corrosive, so there are not so many requirements in terms of materials, so cast steel or cast iron are generally used. Usually it's just a rust-proof paint on the inside and a paint on the outside.
3. The production process and safety are different: This is a typical difference between chemical centrifugal pumps and ordinary centrifugal pumps. Chemical centrifugal pumps have extremely strict requirements in the production process, because a little problem may will cause serious problems. Not to mention safety, the flow, head and pressure of the pump must not only meet the basic requirements, but also ensure that the pump can achieve safety and performance first.

Because the drive shaft does not need to penetrate the pump casing, it uses the thin-walled driving torque of the magnetic field through the air gap and the isolation sleeve to drive the inner rotor, thereby eliminating the leakage channel shaft seal and realizing a complete seal.
There is overload protection when transmitting power.
In addition to the high requirements for magnetic materials and magnetic circuit design, the other technical requirements are not high.
Corrosion resistant submersible pump maintenance and repair work is very small.
Corrosion resistant submersible pump disadvantages:
Corrosion resistant submersible pump efficiency is lower than ordinary centrifugal pump.
The material and manufacturing requirements of the single-sided leakage isolation casing are very high. If the material is improperly selected or the manufacturing quality is poor, the isolation sleeve cannot withstand the friction of the inner and outer magnetic steel, and once it is disconnected, the conveyed medium will overflow.
Corrosion resistant submersible pump is limited by materials and magnetic transmission, so it is only used to transmit media below 100c and below 1.6mpa.
Since the wear resistance of spacer materials is usually poor, corrosion resistant submersible pump is usually used to transport media without solid particles.
Coupling alignment requirements are very high. If the alignment is not correct, it will cause damage to the bearing at the entrance and prevent wear of the one-sided leakage isolation sleeve.
Corrosion resistant submersible pump operation requirements:
Corrosion resistant submersible pump has no aging demagnetization phenomenon over time under normal working conditions. However, when the pump is overloaded or the operating temperature is higher than the allowable temperature of the magnet, demagnetization will occur. Therefore, the corrosion resistant submersible pump must be operated under normal operating conditions.
Corrosion resistant submersible pump is forbidden to avoid burning out the sliding bearing and isolating sleeve. The medium conveyed by corrosion resistant submersible pump is not allowed to contain ferromagnetic impurities and hard impurities. Corrosion resistant submersible pump is not allowed to run under 30% of the rated flow.
Corrosion resistant submersible pump does not require any maintenance methods, but you should always check whether the current temperature rise and outlet pressure are normal, whether the leakage operation is stable, whether the vibration and noise are normal. Under normal circumstances, it is recommended to check every 2 to 3 months. If necessary, you should check at any time and deal with the abnormal situation promptly.
