1、 Fluoroplastic Magnetic Pump CQB-F Product Features:

The leak proof design eliminates the shaft seal and uses magnetic coupling to indirectly drive, completely eliminating the trouble of dripping and not polluting the usage site. Due to the use of "fluoroplastic alloy" for the overcurrent part of the pump. It can continuously transport corrosive media such as acids, alkalis, and strong oxidants of any concentration without damage.

2、 Working principle of CQB-F fluoroplastic magnetic drive pump:

The driving device adopts an active magnetic coupling directly installed on the motor shaft, and the pump chamber is completely enclosed. The impeller with a magnet on the pump shaft is indirectly driven by magnetic coupling, which is compact, reliable and energy-saving.

The sturdy and durable pump body structure, although the liquid contact part is made of fluoroplastic, the pump housing is made of metal material, so the pump body is able to withstand the weight of the pipeline and withstand mechanical impacts.

3、 Installation and commissioning of CQB-F fluoroplastic magnetic drive pump:

（1） Magnetic pumps should be installed horizontally and not vertically. The plastic magnetic drive pump body should not bear the weight of the pipeline. For special requirements for vertical installation, the motor must be facing upwards.

（2） When the suction liquid level is higher than the pump centerline, open the suction pipeline valve before starting. If the suction liquid level is lower than the pump centerline, the pipeline needs to be equipped with a bottom valve.

（3） Before using the pump, it should be checked that the motor fan blades rotate flexibly, without jamming or abnormal noise, and all fasteners should be tightened.

（4） Check if the rotation direction of the motor is consistent with the direction mark of the magnetic pump.

（5） After the motor starts, slowly open the discharge valve and adjust it to the desired opening after the pump enters normal working condition.

（6） Before the pump stops working, the discharge valve should be closed first, and then the power should be cut off.

4、 CQB-F Fluoroplastic Magnetic Drive Pump Product Usage:

The CQB-F fluoroplastic magnetic drive pump is widely used in industries such as petrochemicals, acid and alkali production, non-ferrous metal smelting, acid washing processes in automotive manufacturing, rare earth separation, pesticides, dyes, pharmaceuticals, papermaking, electroplating, and radio.

Operating temperature: -20 ℃ to 12 ℃0 ℃.

use and maintenance

Installation and precautions of fluoroplastic magnetic pump:

1. Prepare the concrete foundation according to the basic dimensions, and provide buried foot bolts at the same time.

2. Before installation, the pump and motor should be inspected to ensure that all parts are intact and free of debris inside the pump.

3. Place a pair of wedge pads between the base plate and the foundation, and use high-speed pads to align the level of the pump.

4. The suction and discharge pipelines of the pump should have brackets and cannot be supported by the pump. The diameter of the inlet and outlet pipelines should be consistent with the diameter of the pump inlet and outlet.

5. When installing the FZB series self-priming pump, the inlet pipe should be connected first, and the outlet pipe should be connected after filling with liquid to correct the direction of rotation. The inlet pipeline of the pump must be matched with the pump and the total length cannot exceed 5 meters.

6. After installation, turn the coupling by hand and check for any scratches.

7. Magnetic pumps are strictly prohibited from extracting media containing particles.

8. To prevent debris from entering the pump, a filter should be installed at the inlet, with a filtration area greater than 3-4 times the cross-sectional area of the pipeline.

9. Pumps with high head should also be equipped with check valves on the outlet pipeline to prevent water hammer damage caused by sudden shutdown.

10. It is necessary to ensure that the installation height of the pump meets the cavitation allowance of the pump, and consider pipeline losses and medium temperature.

11. When the medium temperature is too high, cooling measures should be taken for the mechanical seal to prevent deformation and cracking of the static ring.

Fluoroplastic magnetic pump startup and operation:

1. Before driving, the pump should be filled with the liquid to be transported (if the pump is suction), the outlet gate valve should be closed, and the power supply should be connected.

2. Connect the power and check if the pump's direction of rotation is correct.

3. Test run the unit for 3-6 minutes, and if there are no abnormal phenomena, it can be put into operation.

4. When shutting down, the gate valve at the outlet should be closed first, and then the power should be cut off.

Repair and maintenance of fluoroplastic magnetic pump:

1. Regularly inspect the pump and motor, and replace vulnerable parts.

2. When the pump is not in use for a long time, the flow channel inside the pump should be cleaned and the power should be cut off

3. Air freight transfer is strictly prohibited.
