Overview
The CWB vortex magnetic pump (referred to as the magnetic vortex pump) is a new product that applies the working principle of permanent magnet couplings to centrifugal pumps. It has a reasonable design, advanced technology, full sealing, no leakage, low flow rate, high head, and corrosion resistance. 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 in a completely sealed state, completely solving the problems of running, emitting, and dripping that cannot be avoided by other pump mechanical seals. The CWB vortex magnetic pump uses corrosion-resistant and high-strength engineering plastics, corundum ceramics, stainless steel and other materials as manufacturing materials, so it has good corrosion resistance and can protect the transported medium from pollution.

Product Introduction
The CWB vortex magnetic pump (referred to as the magnetic vortex pump) is a new product that applies the working principle of permanent magnet couplings to centrifugal pumps. It has a reasonable design, advanced technology, full sealing, no leakage, low flow rate, high head, and corrosion resistance. 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 in a completely sealed state, completely solving the problems of running, emitting, and dripping that cannot be avoided by other pump mechanical seals. The CWB vortex magnetic pump uses corrosion-resistant and high-strength engineering plastics, corundum ceramics, stainless steel and other materials as manufacturing materials, so it has good corrosion resistance and can protect the transported medium from pollution.
Product Features
The CWB vortex magnetic pump adopts a magnetic transmission structure to ensure that the pump can be sealed and achieve leak free transportation of corrosive, flammable, explosive, toxic and other chemical media.
1. High head, low flow rate, with a specific speed generally less than 40;
2. Simple structure, small size, and light weight;
3. The CWB vortex magnetic pump has a self-lubricating circuit, which improves the service life of sliding bearings;
4. Add a cooling circuit to promptly remove magnetic eddy current heat;
5. The CWB vortex magnetic pump adopts cantilever blades to reduce the radial force on the impeller;
6. As the viscosity of the conveying medium increases, the efficiency of the CWB vortex magnetic pump decreases sharply. Therefore, the viscosity of the medium should not exceed 5 × 10-6 M3/S.
Product Usage
Magnetic pump has a compact structure, beautiful appearance, small volume, low noise, reliable operation, and easy use and maintenance. Can be widely used in chemical, pharmaceutical, petroleum, reliable, and easy to use and maintain. It can be widely used in chemical, pharmaceutical, petroleum, acid and alkali pumping, oil, rare and valuable liquids, venom, volatile liquids, as well as supporting circulating water equipment and filter machines. Especially for the pumping of liquids that are prone to leakage, flammable, and explosive, this pump is more ideal.

Fault causes and troubleshooting methods
Fault form |
root cause |
exclusion method |
The pump is not producing water |
1. Reverse rotation of water pump 2. Air leakage in the inlet pipeline 3. Insufficient water storage in the pump chamber 4. The voltage is too high, causing the coupling to slip during startup 5. The suction distance is too high |
1. Change the motor wiring 2. Eliminate air leakage 3. Increase water storage capacity 4. Adjust the voltage 5. Lower the installation position of the pump |
Insufficient traffic |
1. The suction pipe diameter is too small 2. Channel blockage 3. High head 4. The speed is too low |
1. Replace the inlet pipe 2. Clean the flow channel 3. Turn up the outlet valve 4. Restore the rated speed |
Head too low |
1. Excessive traffic 2. The speed is too low |
1. Turn down the outlet valve 2. Restore the rated speed |
The noise is too loud. |
1. Severe wear of the shaft 2. Severe wear of the shaft sleeve 3. Drive the magnetic steel cup to contact the isolation sleeve |
1. Replace the pump shaft 2. Replace the shaft sleeve 3. Dismantle the pump head and reassemble it |
