Product Overview

Fluoroplastic magnetic pumps utilize a magnetic coupler to transmit power, offering a fully sealed and leak-free operation. When the motor drives the outer magnetic steel of the magnetic coupler to rotate, the magnetic lines of force pass through the gap and isolation sleeve, acting on the inner magnetic steel, causing the pump rotor to synchronize with the motor's rotation and transmit torque without mechanical contact. Since the liquid is enclosed within the isolation sleeve, it prevents material leakage, reduces pollution, saves energy, purifies the environment, and protects the physical and mental health of personnel on the production line.

1. The pump body lining, inner rotor of the impeller, and isolation sleeve are all made of pure F46 material through one-time molding, ensuring no impurity precipitation, making it suitable for conveying high-purity, highly corrosive chemical liquids;

2. The pump casing is made of ductile iron, designed with standard flanges, offering good mechanical strength and the ability to withstand heavy pipeline loads;

3. The flow-passing components are lined with F46 material, featuring six smooth and unobstructed channels, excellent hydraulic performance, low hydraulic friction loss, and high efficiency;

4. The pump shaft, bearing sleeve, and dynamic/static rings are made of pressureless sintered silicon carbide, characterized by high hardness, high wear resistance, and high corrosion resistance;

5. The unique spiral groove design in the inner hole of the bearing sleeve facilitates lubrication of the sliding bearing pair and dissipates heat generated by friction during pump operation;

6. An additional reinforcement cover made of imported PPS material is added outside the isolation sleeve, enabling the pump unit to withstand higher system pressure and eliminating heat generated by magnetic eddy currents in metal sleeves;

7. The inner and outer magnets are made of neodymium iron boron material, with a magnetic steel surface strength of up to 3600 Gauss, ensuring smooth transmission of the prime mover's torque to the impeller without slipping even under high-flow conditions. It also prevents contact between the inner rotor of the impeller and the rear thrust ring, avoiding melting of fluoroplastic components due to frictional heat and ensuring the magnetic pump operates reliably in highly corrosive environments;

8. The entire pump unit adopts a rear-pull structure, allowing one person to perform internal maintenance and part replacement without the need to dismantle the pipeline.
