Min'an QY Oil-Filled Pump—A High-Efficiency, Durable, and Reliable Solution for Deep-Well Water Lifting
I. Product Overview
The Min'an QY oil-filled pump is a high-efficiency submersible pump integrating the pump unit, sealing system, and a three-phase asynchronous motor. It is specifically designed for deep-well water lifting, agricultural irrigation, and industrial drainage. Its core feature is an oil-filled motor structure that utilizes mechanical oil for both cooling and sealing, ensuring stable operation under conditions involving high temperatures and high discharge heads.
II. Key Features and Benefits
1. High Efficiency, Energy Saving, and Superior Performance
Wide Flow and Head Range: Flow rates range from 15 to 260 m³/h, with heads reaching 6 to 50 meters, making it suitable for demanding applications such as agricultural sprinkler irrigation and water tower supply.
Optimized Hydraulic Design: A multi-stage impeller structure enhances pressure stability, while guide vanes minimize energy loss, resulting in an efficiency improvement of 15%–20% compared to standard pumps.
2. Oil-Filled Motor Technology: Safe and Reliable
Dual-Seal Protection: The motor employs double-end mechanical seals (carbide and ceramic materials) and utilizes fluororubber O-rings for static sealing, effectively eliminating the risk of water ingress.
Oil Cooling System: The motor chamber is filled with No. 5 mechanical oil to facilitate rapid heat dissipation and bearing lubrication; the continuous operating temperature remains ≤40°C, preventing shutdowns due to overheating.
3. Rugged Durability and Corrosion-Resistant Materials
Stainless Steel/Cast Iron Options: The pump body is available in 304 stainless steel or high-strength cast iron, offering resistance to acid and alkali corrosion (pH 6.5–8.5) and suitability for media such as seawater and chemical wastewater.
Sand and Wear Resistance: Impellers and pump casings are constructed from wear-resistant alloys, allowing for a sand content of ≤0.1% (particle size ≤0.2 mm), making the pump ideal for water sources containing impurities.
4. Convenient Installation and Low Maintenance
Compact and Lightweight: Featuring a compact size and light weight, the pump requires no dedicated pump house or priming; it can operate directly while submerged at depths of 0.5 to 5 meters. Modular Structure: The motor and pump body can be quickly disassembled; maintenance requires only periodic inspection of seals and oil changes (every 500 hours).
5. Adaptability
Environmental Compatibility: Suitable for water temperatures ranging from -20°C to +40°C; compatible with three-phase 380V power supply (voltage fluctuation ±10%).
III. Typical Application Scenarios
Agricultural Irrigation: Deep-well water extraction, orchard sprinkler irrigation, and fish pond aeration; meets high-flow rate requirements.
Industrial Drainage: Dewatering in mines and tunnels, and transport of chemical wastewater.
Municipal Engineering: Flood control and drainage, water tower supply, and landscape fountain circulation.
With its oil-immersed sealing technology, high-head capability, and low maintenance costs, the Min'an QY oil-immersed pump stands as a benchmark product in the field of deep-well water extraction. Its versatility and reliable material selection make it particularly well-suited for continuous operation in demanding environments. Users should select the appropriate model based on flow rate, fluid characteristics, and power supply conditions to ensure optimal performance.
