Difference between magnetic pump and centrifugal pump

Magnetic pump is a centrifugal pump, pump, magnetic actuator, motor consists of three parts. Ordinary centrifugal pump motor directly driven pump impeller, or driven by the coupling impeller The magnetic pump is driven by the magnetic impeller. No mechanical seal, effectively prevent water leakage. But the magnetic pump can only do part of the low-power magnetic drive by the internal and external magnetic rotor components; spacer and the magnetic medium within the rotor and the isolated magnetic rotor; external magnetic rotor driven by the motor, the use of magnetic flux characteristics of the rotating magnetic rotor Rotate, complete the non-contact torque transfer, so as to achieve the purpose of driving the pump. Magnetic pump, the structure is simple and compact. Unique lubrication and cooling circuit, a part of the process of liquid self-lubricating and cooling transmission components, eliminating the need for mechanical seal pump cooling, washing, quenching and other complex systems. Design inlet pressure up to 30MPa, mechanical seal pump is difficult to do this. Compared with the use of mechanical seal or packing seal centrifugal pump, the magnetic pump has the following advantages: 1. Pump shaft seal by the dynamic seal into a static, completely avoiding the media leakage; 2. Without independent lubrication and cooling water, reducing energy consumption; 3. Driven by the coupling into a synchronous drag, there is no contact and friction. Low power consumption, high efficiency, damping and damping effect, reducing the influence of motor vibration on the pump and the pump on cavitation vibration impact on the motor; 4. Overload, the relative rotation of the rotor inside and outside, on the motor, pump protection.
