CQF engineering plastic magnetic pump  is a new type of pump that uses the working principle of permanent magnet coupling to transmit torque without contact. When the prime mover drives the outer magnet to rotate, the inner magnet rotor is driven to rotate synchronously through the action of the magnetic field, and the inner magnet The steel rotor and impeller are integrated to achieve the purpose of driving the impeller to rotate without contact. Since the liquid is enclosed in a static isolation sleeve, the magnetic pump is a fully enclosed, leak-free product, thus completely eliminating the inevitable problems of running, popping, dripping and leaking of mechanically sealed centrifugal pumps.

CQF engineering plastic magnetic pump Product use:

The CQF engineering plastic magnetic pump has compact structure, beautiful appearance, small size, low noise, reliable operation, and easy use and maintenance. It can be widely used in chemical industry, pharmaceutical, petroleum, electroplating, food, film photography and printing, scientific research institutions, national defense industry and other units to pump acid, alkali, oil, rare and precious liquid, venom, volatile liquid, and supporting circulating water equipment. Filter package. Especially for pumping leaking, flammable and explosive liquids, this pump is more ideal.

Working conditions of CQF series magnetic engineering plastic centrifugal pump

The density of the medium transported by the magnetic pump is not more than 1300kg/m3, and the viscosity is not more than 30×10-6m3/S. It does not contain ferromagnetic and fiber-free liquids. The rated temperature of conventional magnetic pumps: if the pump body is made of metal or F46 lining, the maximum working temperature is 80°C, and the rated pressure is 1.6MPa; the operating temperature of the high-temperature magnetic pump is ≤350°C; if the pump body is made of non-metallic material, the highest The temperature does not exceed 60℃, and the rated pressure is 0.6MPa. For liquids with a medium density greater than 1600kg/m3, the magnetic coupling needs to be designed separately. The bearings of the magnetic pump are lubricated and cooled by the transported medium. The drum magnetic pump is strictly prohibited from running without load.

The engineering plastic magnetic pump adopts magnetic coupling transmission without mechanical seal, which completely solves the problem of dripping. Designed according to ISO2858 standard. The plastic magnetic pump has a compact structure, reliable performance, and is extremely convenient to use and maintain. Magnetic pump products are widely used in petrochemical industry, automobile manufacturing, acid production, alkali production, non-ferrous metals, military scientific research, metallurgy and papermaking, pesticides, electroplating and other industries.

Installation and use of engineering plastic magnetic pump:

1. The magnetic pump should be installed horizontally and not vertically. The plastic pump must not bear the weight of the pipeline. For special vertical installation 

occasions, the motor must be facing upward.

2. When the suction liquid level is higher than the pump axis, just open the suction pipe valve before starting. If the suction liquid level is lower than the pump axis, 

the pipeline needs to be equipped with a bottom valve.

3. The pump should be inspected before use. The motor blades must rotate flexibly without jamming or abnormal noise, and all fasteners must be tightened.

4. Check whether the rotation direction of the motor is consistent with the steering mark of the magnetic pump.

5. After the motor starts, slowly open the discharge valve. After the pump enters normal working condition, adjust the discharge valve to the required opening.

6. Before the pump stops working, the discharge valve should be closed first, and then the suction pipe valve should be closed.
