The magnetic pump housing consists of the pump body and pump cover, which are responsible for withstanding all the operational pressure of the pump. The hydraulic design of the impeller in the pump body adheres to the API685 standard, making it a critical component that defines the hydraulic performance of the magnetic pump. Its primary function is to induce rotation in the liquid, converting mechanical energy from the prime mover into fluid energy.
The rotor assembly of the magnetic pump includes two main sections: one mounted on the pump shaft and another on the driving shaft. The pump shaft plays a vital role in supporting the impeller and inner rotor while transmitting torque. Components such as the impeller, bearing, thrust ring, and inner magnetic rotor are attached to the pump shaft, forming a rotor section that comes into direct contact with the pumped medium. On the other side, the rotating parts on the drive shaft consist of the outer magnetic rotor, rolling bearings, drive shaft bushing, and the drive shaft itself, creating a separate rotor section that remains in an air environment.
The connecting components of the magnetic pump include the frame, bearing housing, and other static elements that provide structural support and alignment. Sliding bearings, bushings, and thrust plates serve as key support and positioning components for the rotor assembly.
The transmission system of the magnetic pump utilizes a diaphragm coupling that connects the pump to the prime mover. This diaphragm-type coupling allows for easy maintenance, as the magnetic diaphragm can be accessed and repaired by simply removing the intermediate diaphragm of the coupling.
The inner and outer rotors work in conjunction to form the magnetic transmission mechanism of the pump. This magnetic coupling enables power transfer without direct mechanical contact, ensuring a sealed and leak-free operation.
One of the most important components of the magnetic pump is the isolation sleeve, which is the only part that guarantees complete leakage prevention. It acts as a barrier between the moving and stationary parts of the pump, maintaining the integrity of the system.
Since the pump shaft is exposed to the process medium, it must be made from materials that offer high corrosion resistance, precise machining, and sufficient strength. In some cases, heat treatment may be applied to enhance its mechanical properties.
