The 150QJP Series Special Fountain Submersible Pump is a high-efficiency engineering solution specifically designed for professional landscape architecture. Featuring a motor core constructed from premium cold-rolled silicon steel, this series ensures exceptional magnetic permeability and maintains stable thermal performance even during frequent start-stop cycles. By replacing traditional ball bearings with water-lubricated alloy copper sleeves, we have effectively eliminated the risks of rust and motor burnout caused by oil deficiency, ensuring long-term reliability in demanding environments.

Engineered for versatility and safety, the QJP series integrates advanced intelligent protections, including over-temperature and anti-dry burning systems. Whether deployed in municipal squares, botanical gardens, or luxury landscape engineering, these pumps provide a seamless blend of high flow rates and energy efficiency. Designed using computer CAD technology, the pump delivers a robust structure that minimizes vibration and noise, making it the ideal choice for aesthetic water features and industrial water intake.

Frequently Asked Questions

Q: What are the ideal application scenarios for the 150QJP pump?

The 150QJP is ideal for landscape fountain decoration in squares and gardens, high-rise water supply, agricultural and garden irrigation, as well as river and deep well water intake.

Q: How does the water-lubricated alloy copper sleeve benefit the pump?

Unlike traditional ball bearings, these sleeves avoid rust and the risk of motor burnout caused by oil lack, significantly increasing the pump's lifespan in submerged conditions.

Q: What safety precautions must be taken during installation?

The motor cavity must be completely filled with clean water before use, the pump must be installed vertically, and a reliable grounding system must be established to prevent electric shock.

Q: Can this pump be used for muddy or sandy water?

No, this is a clean water pump. Pumping sediment or muddy water is strictly prohibited as it may cause premature wear to the impellers and bearings.

Q: What should I do if the pump vibrates violently during operation?

Shut down the machine immediately. Check for jamming, ensure the pump is centered in the well pipe, and verify that the current is within the rated range.

Q: How often should the 150QJP series be maintained?

The unit should be disassembled and inspected every year, or every two years if it has been immersed but not operated continuously, to replace wearing parts like the impeller and sealing rings.
