Solar PumpThe working principle
The brushless DC magnetic drive pump consists of a magnet and impeller molded together to form the motor's rotor. The rotor features a sleeve molded directly in the center, which is fixed in the housing with a high-performance ceramic shaft. The motor's stator and circuit board section are encapsulated in the pump body with epoxy resin, separated from the rotor by a thin-wall isolation, eliminating the need for traditional mechanical shaft seals, thus ensuring complete sealing. The motor's torque is generated by the coil on the silicon steel sheet (stator) producing a magnetic field that drives the permanent magnet (rotor) to operate.n (nFor even numbers) Partial magnets are coupled into a complete magnetic system through magnetic charging. When the magnetic poles generated by the stator coil are opposite to the poles of the magnet, i.e., the displacement angle Φ between the two poles.=0At this moment, the magnetic system's magnetic energyZWhen the poles rotate to opposite poles facing each other, that is, the displacement angle Φ between the two poles.=2π/nAt this moment, the magnetic system's magnetic energyZAfter removing external forces, the magnetic system's poles repel each other, causing the magnet to return to its magnetic energy state.ZLow state. Therefore, the magnet generates movement, driving the magnetic rotor to rotate.
Brushless Direct-Drive Water PumpThrough electronic commutation, without the need for carbon brushes, both the magnet rotor and stator silicon steel sheets feature multi-level magnetic fields. As the magnet rotor rotates relative to the stator by an angle, it automatically changes the magnetic pole direction, ensuring that the rotor maintains a same-level repulsion, thereby allowing the brushless DC magnetic isolation pump to achieve high speed and efficiency.
The stator and rotor of the magnetic isolation pump are completely isolated, completely avoiding the traditional brushless motor design.Direct-Flow PumpLiquid leakage issues have been addressed. Moreover, it is fully submersible and waterproof, effectively enhancing the pump's lifespan and performance.
Combine Folding Principles
Foldable Communication Solar Water Pump
On sunny days, solar panels generate direct current (DC) electricity, which is then converted into alternating current (AC) electricity for use by AC motors via an inverter. At the same time, the inverter is responsible for...ControllerEffectiveness.
FoldedDirect Current Solar Pump
Directly utilize DC electricity generated by solar panels. Since the pump itself is an inductive load, it requires a slightly higher starting current. To ensure operation even when sunlight is weak, a solar controller must be added, which can provide a large instantaneous starting current during slightly reduced sunlight. The direct water pump is highly efficient, with high speed, high head, compact size, and enhanced safety.
Folded Editing Section Composition and Features
The Brushless Direct-Flow Pump (Magnetic Isolation Pump) is composed of several parts: the pump body (isolation piece), motor stator, shaft, bearings, and the impeller blade (magnet and impeller).

Neodymium-Iron-Boron Permanent Magnet
Permanent magnets made from rare earth permanent magnetic materials feature a wide operating temperature range.(-45－400℃)High矫顽力, with excellent anisotropy in magnetic field direction, it does not exhibit demagnetization when poles are close to each other, making it an excellent magnetic field source.
Cautionary Notes
Prevent Particle Entry with Folding Design
(1)No ferromagnetic impurities or particles are allowed to enter the magnetic drive and bearing friction pair.
(2)Ensure timely flushing after transporting media that is prone to crystallization or precipitation.(After shutting down the pump, pour clean water into the pump chamber and operate.1minRear compartment cleared out)To ensure the service life of sliding bearings.
(3)When conveying media containing solid particles, filtration should be performed at the pump inlet pipe.
Anti-Relaxation Folding Prevention
Direct-Flow Pump
The equipment should operate under specified temperature conditions, and it is strictly prohibited for the medium temperature to exceed the limit. A platinum resistance temperature sensor can be installed on the outer surface of the magnetic pump's isolation sleeve to detect the temperature rise in the gap area, allowing for alarms or shutdowns to occur when the temperature exceeds the limit.
Fold Prevention against Dry Friction
Minimize idle time.
