1、 Fluoroplastic self-priming magnetic pump product usage：
ZMD fluoroplastic self-priming magnetic pump has launched a new generation of corrosion-resistant self-priming magnetic pump for the company. It not only combines the advantages of fluoroplastic magnetic pump, but also has the biggest function of self-priming and no leakage, which cannot be achieved by all previous fluoroplastic magnetic pumps. Therefore, this series of pumps has been welcomed by a large number of users since its launch. This series of pumps can be widely used in industries or workflows such as chemical industry, non-ferrous metal smelting, pesticides, acid and alkali production, papermaking, acid washing process, rare earth separation, electroplating, electronics, chemical foil, acid and alkali unloading, etc. It is currently one of the most innovative products in magnetic pump varieties, with high efficiency, energy saving, safety and practicality.
The applicable temperature of ZMD fluoroplastic self-priming magnetic pump is -20 ° C-100 ° C.
2、 Design characteristics of fluoroplastic self-priming magnetic pump：
The ZMD fluoroplastic self-priming magnetic pump combines all the excellent features of a magnetic pump, and its biggest advantage is the ability to self-priming, with a self-priming height of 2-4 meters. It fully combines all the advantages of fluoroplastic self-priming pumps and fluoroplastic magnetic pumps, with both self-priming function and elimination of shaft seals. It uses magnetic coupling for indirect transmission, completely eliminating the phenomenon of dripping.
The ZMD fluoroplastic self-priming magnetic pump adopts the latest synthetic material to make the isolation sleeve, which has high-strength mechanical properties and completely eliminates the magnetic eddy current phenomenon commonly found in magnetic pumps. By adopting a unique rear pull structure, one person can easily carry out internal maintenance and parts replacement without dismantling pipelines, greatly facilitating daily maintenance and upkeep work.

Precautions for using fluoroplastic self-priming magnetic pump:
(1) Installation method and connection requirements:
1. Prepare the concrete foundation according to the basic dimensions and embed the anchor bolts. Place the unit on the foundation, align the pump horizontally, and tighten the foundation bolts. The pump should be located as close as possible to the water tank.
2. The diameter of the inlet pipe of the pump shall not exceed the specified requirements, and the total length of the inlet pipe shall not exceed 5m. The shorter the pipe, the better, provided that the requirements are met. A filter screen must be installed at the bottom of the inlet pipe to prevent excessive particles or debris from entering the pump body and damaging the impeller or affecting the pump's operation. The filtration area should be greater than 3-4 times the cross-sectional area of the pipeline.
3. Valves must be installed in the outlet pipeline of the pump to regulate the flow rate, so that the pump can operate at the specified flow rate and prevent the pump from being unable to operate after exceeding the limit. The outlet pipe diameter shall not be less than the specified requirements, and the larger the outlet pipe diameter, the better if possible. The total length of the outlet pipe must be greater than 1.5 times the total length of the inlet pipe, and it is better to be longer if possible.
4. The weight of the inlet and outlet pipelines should not be supported on the inlet and outlet flanges of the pump, but should be fixed on their respective brackets. The various parts connected to the inlet and outlet pipelines must be tight and leak free, otherwise it will affect the self-priming function and the normal operation of the pump.
(2) Usage and maintenance instructions:
1. Self suction magnetic pumps are strictly prohibited from conveying media containing solid particles or easily crystallized materials. Continuous operation is not allowed with the discharge outlet closed, and the minimum flow rate must be maintained.
2. When installing pipelines, connect the inlet pipe first, fill it with liquid, and then connect the outlet pipe.
3. After installation, connect the power supply and check whether the pump rotates flexibly by jogging, and whether the motor direction is consistent with the direction mark.
4. Open the outlet valve by about one-third to start the self-priming pump (i.e. open the valve to start), and then slowly adjust the outlet valve to prevent the pump from working properly.
5. During infusion, the flow rate, head, and self-priming height must be controlled within the specified range and cannot differ too much, otherwise it may cause suction and prevent the pump from working properly.
6. The self-priming pump is not allowed to produce suction phenomenon during operation. Once suction occurs, it must be drained and refilled with fluid before self-priming. Therefore, users must have a device to control the lowest liquid level or assign a dedicated person to supervise to prevent the medium in the pool from being sucked out.
7. Self priming pumps cannot transport media that generate large amounts of bubbles, nor can they transport gas-liquid mixtures.
8. When transporting media that are prone to crystallization, if the pump is stopped for a period of time and not in use, the pump chamber must be flushed to prevent residual crystallization media and prevent damage when the pump is restarted after crystallization; When reusing, add the required liquid before self suction.
9. When transporting non crystalline media, if the pump is stopped for a long time before use, check whether the liquid in the pump body is sufficient before starting, and make up for it before self suction.
10. When the pump is used in an environment below the liquid level or as a substitute for a pipeline pump, air valves and buffer valves cannot be used. In this case, please remove the air valve and buffer valve.
11. Check valves shall not be installed in the pump outlet pipeline. If any, a vent hole shall be provided at the lower end of the check valve.
