HuaPin Power Technology (Jiangsu) Co., Ltd., part of the HuaPin Holding Group, leverages the group’s global inverter industry ecosystem incubation base. With its unique advantage as the inventor of the "core" technology behind variable-frequency drives—technology developed without compromise or compromise in perception—the company integrates industry structure strengths along with its expertise in drive systems, complete machine applications, hydraulic components, and fluid power integration technologies. Together, these capabilities enable the creation of a low-carbon fluid power ecosystem, providing comprehensive support to industrial clusters such as deep-well pump manufacturing.
HuaPin Power's high-speed permanent magnet deep-well pump features a uniquely designed integrated installation structure that combines a permanent magnet motor with a variable-frequency control system. Weighing just one-quarter of conventional pumps at the same power level and standing only one-third as tall, this innovative design also boasts a control system that occupies merely one-third the space of typical controllers in the pump industry. The pump operates across a wide speed range—from 6,000 to 10,700 RPM—effectively overcoming technical barriers for 2-inch, 3-inch, and 4-inch high-speed deep-well pumps in the 0.37- to 3-kW power class. Equipped with Hall-less technology and featuring a busbar system devoid of large capacitors, the pump incorporates a single-tube IGBT along with a proprietary, patented drive-control algorithm. This advanced design not only minimizes voltage drop caused by cables ranging from 50 to 150 meters but also ensures superior product performance while enhancing safety and quality assurance.
