Copper Wire Oil Filled Submersible Pump

This QY 3HP cast iron oil-filled pump was developed over a decade ago to resolve three core pain points of overseas agricultural bulk procurement: fragile thin plastic pump shell easy to crack during transportation, frequent motor burnout due to insufficient heat dissipation, and unstable water flow output under rural voltage fluctuation. The technical team adopted thickened integral cast iron casting to upgrade structural strength, designed fully enclosed independent oil cooling chamber to optimize thermal control efficiency, and added dual overload protection modules to stabilize hydraulic output. After simplifying assembly workflows for mass production and unifying spare part specifications, the standardized wholesale 3HP version was finalized, supporting OEM cable length and outlet pipe size customization for international bulk importers.

1.Robust Cast Iron Integrated Structure.The whole pump body adopts thick high-density cast iron one-piece casting, with outstanding impact resistance to prevent shell cracking during cross-border transportation and field moving.
2.Efficient Oil Cooling Thermal Control System.As an Energy Efficient Oil-Cooled Pump, it suppresses excessive temperature rise under 24h heavy-load operation, drastically cutting motor burnout failure rates on farms.
3.Consistent & Reliable Running Stability.Matched 3HP mixing flow impeller plus dual electrical protection modules keep steady flow and lift output. It works as a Stable Performance Pump even when local rural power grids have obvious voltage swings, avoiding unexpected shutdowns during peak irrigation seasons.
4.Intelligent Automatic Safety Protection.Dual over-temperature and over-current protection devices cut power supply once the pump is blocked or overloaded, providing reliable safety guarantee for unattended farm water pumping work.
