The QY oil-filled submersible electric pump is an engineered, high-efficiency submersible electric pump designed for demanding water transfer, deep well pumping, and fluid circulation applications. Built with a robust, specialized oil-filled motor architecture, this premium oil-filled submersible pump provides exceptional self-cooling performance, superior internal mechanical lubrication, and reliable overload protection—even under continuous, heavy-duty operation in challenging environments.
Manufactured with high-strength, corrosion-resistant materials and precision centrifugal impellers, the QY oil-filled submersible electric pump delivers an optimized combination of strong water flow, high-head vertical lift, and low energy consumption. Its compact, streamlined vertical profile allows for quick, trouble-free installation in deep wells, open reservoirs, natural rivers, and complex agricultural irrigation channels.
Unlike standard water-filled pumps that risk internal scale buildup and premature bearing wear, our advanced oil-filled submersible pump utilizes food-grade or industrial-grade mechanical cooling oil.



Main Advantages & Value Proposition
Choosing the QY oil-filled submersible electric pump introduces distinct competitive advantages to your machinery inventory or fluid engineering setups:
Excellent Thermal Cooling Performance: The internal lubricating oil constantly transfers heat away from the motor windings directly to the pump shell. This design ensures that the submersible electric pump runs exceptionally cool during continuous duty cycles.
Extended Bearing & Shaft Lifespan: Because the entire motor cavity is immersed in protective mechanical oil, the bearings and mechanical seals are continuously lubricated, eliminating friction wear and extending service life.
High-Head Centrifugal Efficiency: Equipped with balanced centrifugal impellers, this oil-filled submersible pump creates stable water pressure and robust volumetric flow to handle long-distance water delivery.
Low Vibration & Quiet Operation: The oil medium acts as a natural acoustic dampener inside the motor shell, lowering operational noise and structural vibrations to a bare minimum.
Adaptable Vertical Configuration: Its space-saving design permits easy vertical immersion into narrow sumps, rivers, and standard borehole casings without requiring elaborate concrete foundations.
Advanced Manufacturing Craftsmanship & Structural Features
At our 2,891 square meter modern manufacturing facility, the QY oil-filled submersible electric pump is produced using automated machining centers and strict engineering tolerances:
Premium Oil-Filled Motor Engineering
The motor core is housed in an oil-filled chamber that acts as an insulation barrier against moisture and scale. We utilize high-grade, non-toxic dielectric oil, ensuring that even in the unlikely event of a seal breach, surrounding agricultural water remains safe and unpolluted.
100% Pure Copper Wire Windings
Every submersible electric pump is built with 100% pure copper motor wire. This configuration ensures superior electrical conductivity, optimal torque curves, and high thermal resistance, preventing coil melt or motor burnouts during peak usage.
Strict Quality Standards & B2B Custom Services
As a leading international manufacturer and exporter of specialized oil-filled submersible pumps, our operations are governed by world-class quality control protocols.
[Rigorous 4-Step Factory Testing]
Motor Insulation -> Oil Chamber Pressure -> Centrifugal Flow Rate -> 100% IP68 Submersion Check
Every single QY oil-filled submersible electric pump is subjected to a mandatory 100% comprehensive testing process before being packed into export-grade crating. We test electrical leakage under load, sealing vacuum thresholds, and hydrostatic pressure performance.
Strategic B2B OEM & ODM Customization:
Electrical Modifications: Custom voltages, targeted single/three-phase wiring setups, and extended heavy-duty submersible rubber cables.
Metallurgical Adjustments: Upgrading structural parts to premium stainless steel for specialized, mildly corrosive water environments.
Commercial Branding: Precise laser logo etching, tailored product nameplates, and custom graphic box designs for distribution networks.

Q1: What are the main benefits of an oil-filled submersible pump compared to a water-filled model?
A: Water-filled pumps can suffer from internal rust, limescale deposits on the rotor, and dry bearing friction over time. The QY oil-filled submersible electric pump keeps its motor completely immersed in oil, providing continuous lubrication, rust prevention, and superior cooling, which leads to a longer product lifespan.
Q2: Does the cooling oil inside the QY electric water pump require frequent changing?
A: No. The motor chamber is completely sealed at our factory. Under normal operating conditions, the internal oil does not require replacement or top-ups. It is designed to last for the entire operational lifespan of the pump's mechanical seals.
Q3: Can this pump handle water with heavy mud or debris?
A: The QY series features centrifugal impellers optimized for clean or slightly turbid water. While the built-in inlet strainer blocks large particles, pumping thick mud, slurry, or heavy weeds will increase wear and potentially clog the fluid channels. For heavy mud, a dedicated sewage cutting pump is recommended.
Q4: Do you offer regional voltage configurations for global distribution?
A: Yes! We offer comprehensive OEM electrical customization. We can configure the submersible electric pump to support 110V/220V for residential grids or 380V/415V (50Hz or 60Hz) for industrial and agricultural three-phase grids.
