The hydraulic model used by Corrosion Resistant Submerged Pump, according to the performance parameters of the IS type centrifugal pump and the unique structural combination of vertical pumps, and is designed in accordance with ISO2858, which encloses a hard alloy mechanical sealing device. The product is in line with the national standard JB / T53028-93 standard requirements, which is a new generation of energy saving, environmentally-friendly centrifugal pump. This series of pumps are excellent in performance, high reliability, long life, reasonable structure, beautiful appearance, and industry level.
Corrosion Resistant Submerged Pump Structure:
1. Motor: Directly connect to the water pump to transfer power, using an extension shaft motor.
2. Pump shaft: coaxial with the motor, eliminate the motor, ensuring concentricity of the shaft, so that the pump is operated smoothly. The noise is low, the vibration is small, and chrome-plated treatment is used to enhance the service life.
3. Water Water: Prevent the motor in water due to water leakage.
4. Mechanical seal: made of stainless steel, tungsten carbide, fluorine rubber and other materials. Balanced high temperature. High pressure mechanical sealing, long operating life, not easy to leak, no wear, no stream, and ensure the cleanliness of the work environment.
5. Repairing the plug: The pressure gauge can be installed intuitively monitor the operation of the pump.
6. Pump body: The pressurized plugs and suction room are designed to be designed, and there is a installation foot, which is easy to install and run.
7. Plug: The pump is turned into the air in the pump to ensure the normal start of the pump.
8. Impeller: Designed with reasonable hydraulic models, better reliability.
Corrosion Resistant Submerged Pump is used for other liquids for transportation and physical chemistry properties similar to water, suitable for industrial and urban water supply and drainage, high-rise building boost water, garden sprinkle irrigation, fire boost, long-distance delivery, HVAC cooling cycle , The bathroom and other cold and warm water cycles and equipment are supported, and the temperature T <80 ° C is used.

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.
