Product details
product overview
Applying the working principle of permanent magnet couplings to new products of centrifugal pumps, with reasonable design, advanced technology, fully sealed, leak free, and corrosion-resistant characteristics, its performance has reached the advanced level of similar foreign products.
Magnetic pumps replace dynamic seals with static seals, ensuring that the overcurrent components of the pump are completely sealed, completely solving the problem of leakage, seepage, and dripping that cannot be avoided by other pump mechanical seals. Magnetic pumps use corrosion-resistant and high-strength engineering plastics, corundum ceramics, stainless steel, and other materials as manufacturing materials, so they have good corrosion resistance and can protect the transported medium from pollution.
purpose
Magnetic pump has a compact structure, beautiful appearance, small volume, low noise, reliable operation, and easy use and maintenance. It can be widely used in chemical, pharmaceutical, petroleum, electroplating, food, film photography and printing, scientific research structures. National defense industry and other units pump acid, alkali solution, oil, rare and valuable liquids, venom, volatile liquids, as well as supporting equipment for circulating water and filter machines. Especially for the pumping of liquids that are prone to leakage, flammable, and explosive, this pump is more ideal.
1. The pump is a vertical structure with the same inlet and outlet diameters and located on the same centerline. It can be installed in pipelines like a valve, with a compact and beautiful appearance, small footprint, and low construction investment. If a protective cover is added, it can be used outdoors.
2. The impeller is directly installed on the extended shaft of the motor, with a short axial dimension and compact structure. The pump and motor bearings are reasonably configured, which can effectively balance the radial and axial loads generated by the pump operation, ensuring smooth operation, low vibration, and low noise of the pump.
3. The shaft seal adopts mechanical seal or a combination of mechanical seals, using imported titanium alloy sealing rings, medium-sized high-temperature resistant mechanical seals, and hard alloy materials for wear-resistant seals, which can effectively extend the service life of mechanical seals.
4. Easy installation and maintenance, no need to disassemble the pipeline system, just remove the pump coupling nut to extract all rotor components.
5. Pumps can be operated in series or parallel according to the requirements of flow rate and head.
6. The outlet of the pump can be installed in several different directions, such as 0 °, 90 °, and 180 °, to meet different connection scenarios.
1. The suction pressure is ≤ 1.0MPa, or the maximum working pressure of the pump system is ≤ 1.6MPa, that is, the pump suction inlet pressure+pump head is ≤ 1.6MPa. Please specify the system working pressure when ordering. When the working pressure of the pump system is greater than 1.6MPa, it should be separately stated when ordering, so that more reasonable materials can be used for the overcurrent and connection parts of the pump during manufacturing.
2. The ambient temperature is less than 40 ℃ and the relative humidity is less than 95%.
3. The volume content of solid particles in the conveyed medium shall not exceed 0.1% of the unit volume, and the particle size shall be less than 0.2mm.
4. The altitude of the usage environment should not exceed 1000 meters. If it exceeds, it should be mentioned when placing an order to provide you with more reliable products.
Attention: Before selecting or installing the pump, it is necessary to ensure that the actual usage conditions of the pump comply with the above terms to ensure the correct use of the pump!

6. ISWD, IRWD, IHWD, IHWD, ISWBD, IHWBD type horizontal low-speed centrifugal pumps are suitable for occasions with low environmental noise requirements and air conditioning circulation pumps.
1. Before installation, the fastening body of the unit should be checked for looseness, and the flow channel of the pump body should be checked for foreign objects to prevent damage to the impeller and pump body during pump operation.
2. The weight of the pipeline should not be added to the water pump during installation to avoid deformation of the pump.
3. The foundation bolts must be tightened during installation to avoid the impact of vibration on pump performance during start-up.
4. For the convenience of maintenance and safety of use, install one regulating valve on each inlet and outlet pipeline of the pump
5. Install a pressure gauge near the pump outlet to ensure operation within the rated head and flow range, ensuring the normal operation of the pump and extending its service life.
6. After installation, the pump shaft should be moved, and there should be no friction sound or jamming phenomenon of the impeller. Otherwise, the pump should be disassembled to check the cause.
7. There are two types of pump installation: rigid connection installation and flexible connection installation (see connection method).
Start and Stop
Preparation before starting:
1. Rotate the motor fan blades by hand, and the impeller should have no jamming or grinding phenomenon, and rotate flexibly. 2. Open the inlet valve, open the exhaust valve to fill the entire pump chamber with liquid, and then close the exhaust valve. 3. Manually rotate the pump to allow lubricant to enter the mechanical seal end face. 4. Tap the motor to confirm if the steering is correct.
Start up and operation:
1. Fully open the inlet valve. 2. Close the valve of the discharge pipeline. 3. Connect the power supply, gradually open the valve on the discharge pipeline when the pump reaches normal speed, and adjust it to the desired working condition. 3. Pay attention to the instrument readings and check the leakage of the shaft seal. Under normal circumstances, the mechanical seal leakage is less than 3 drops per minute. Check that the temperature at the motor and bearing is ≤ 70 ℃. If any abnormal situation is found, it should be dealt with in a timely manner.
parking:
1. Gradually close the valve of the discharge pipeline and cut off the power supply. 2. Close the inlet valve. 3. If the ambient temperature is below 0 ℃, the liquid inside the pump should be drained to prevent freezing and cracking. 4. If the pump is not used for a long time, it should be disassembled, cleaned, packaged and stored.
Pump maintenance
1. Maintenance during operation:
(1) The imported pipeline must be filled with liquid, and the pump is prohibited from running for a long time in a cavitation state. (2) Regularly check the motor current value and ensure it does not exceed the rated current of the motor. (3) After long-term operation of the pump, if the noise and vibration of the unit increase due to mechanical wear, it should be stopped for inspection. If necessary, vulnerable parts and bearings can be replaced. The overhaul period of the unit is generally one year.
2. Mechanical seal maintenance
Mechanical seal lubrication should be clean and free of solid particles. (2) It is strictly prohibited for mechanical seals to work under dry grinding conditions. (3) Before starting, the pump (motor) should be turned a few times to avoid sudden starting causing damage to the graphite ring. (4) The allowable leakage rate for sealing is 3 drops per minute. Otherwise, it should be checked.
