Product Description
Product Overview:
The QY series oil‑immersed submersible electric pumps are integrated power‑driven irrigation and drainage units that combine a pump with a three‑phase induction motor. The motor is filled with oil, which provides excellent cooling, significantly reducing temperature rise and enhancing the pump’s overload capacity. Moreover, the pump’s bearings operate in the oil, ensuring reliable lubrication and cooling; as a result, their service life is longer than that of other submersible pumps. In addition, the pump is equipped with a dedicated overcurrent protection device that automatically activates under conditions of severe undervoltage, overload, or phase loss, thereby improving the unit’s operational reliability.
Product用途:
This series of submersible pumps is compact and lightweight, making it ideally suited for well‑bottom pumping, agricultural irrigation, landscape watering, post‑rain flood drainage, and domestic water supply; it can also be used for water supply and drainage in industrial and mining enterprises.
