From the appearance, the 4000 rpm solar water pump has a compact design and smooth lines. It is not only beautiful and generous, but also more ergonomic. There are special openings on both sides of the water outlet of the water pump, through which the rings in the gift accessories can be passed, and then the fixed rope can be passed through the rings, making installation and removal more convenient. The outer shell is made of durable stainless steel with excellent impact resistance. Whether it is under the scorching sun or in the face of adverse weather conditions, it can effectively protect the internal components and ensure long-term stable operation.

The water pump impeller is a key component, and high-quality plastic or 304 stainless steel impellers are selected. It is not easy to wear under high-speed rotation, which can ensure efficient pumping capacity and provide sufficient water for farmland.

As the core to ensure the stable operation of the water pump, the bearing adopts high-precision Japanese NSK bearings, and the bottom double shaft The bearing structure has a larger angular contact area, which can effectively reduce energy loss and operating noise, making the water pump stable and reliable at a high speed of 4000 rpm.

Let's look at its core power - permanent magnet brushless motor. The magnetic steel inside the motor is made of high-performance 40SH neodymium iron boron material, which has extremely high magnetic energy product and coercive force, ensuring that the motor generates a strong and stable magnetic field and provides efficient power output. The winding uses high-purity oxygen-free copper wire with excellent conductivity, effectively reducing resistance loss and improving motor efficiency. At the same time, the stator and rotor core of the motor are made of high-quality cold-rolled 600 silicon steel sheets made through special stamping and lamination processes, effectively reducing hysteresis and eddy current losses and improving motor performance.
