Product Overview
The high-speed, efficient, and energy-saving water-filled electric motor solar pump is a new product independently developed by our company. This product features a water-filled shielded brushless permanent magnet motor drive and is equipped with an intelligent controller. The AC and DC conversion allows for high-speed operation, breaking through many bottlenecks of traditional deep well pumps. The motor includes a built-in electronic device that incorporates the motor controller’s features.
The shielded design eliminates the need for mechanical seals, avoiding the risk of leakage caused by wear on mechanical seals. It also prevents efficiency reduction due to friction from mechanical seals, while providing good cooling for the rotor.
Using water-lubricated bearings and water-thrust lubricated bearings as support points, the pump operates quietly even under load. The stainless steel sleeve shielded rotor protects against corrosion and oxidation of the magnetic steel, while the stainless steel sleeve shielded core effectively dissipates heat. The entire structure is made of precision-cast stainless steel 304, and the casing is crafted from welded stainless steel 304. All major components are welded using advanced laser welding equipment.
This product is widely used in villages, schools, hospitals, farms, ranches, remote areas, regions with electricity shortages, construction sites, small water plants, household water supply, water tank applications, and irrigation.
