The 300QJP Series is a high-performance special fountain submersible pump engineered for precision and reliability. Featuring a motor core crafted from premium cold-rolled silicon steel, this pump delivers exceptional magnetic conductivity and high operational efficiency. Designed specifically to handle frequent starting cycles without overheating, it is the ideal solution for musical fountains and large-scale water features requiring stable and powerful performance.
To ensure maximum longevity in submerged environments, the 300QJP replaces traditional ball bearings with advanced alloy copper sleeves and stainless steel components, effectively eliminating rust and burnout caused by oil wear. With a robust water-filled wet motor structure and a precision-engineered sand-blocking system, this series guarantees seamless operation in clean water applications, providing an optimal balance of flow rate and lift for professional water engineering projects.

Frequently Asked Questions
Ensure the motor cavity is completely filled with clean, non-corrosive water before deployment. The pump must be fully immersed in water during operation to facilitate cooling and lubrication.
The 300QJP series is designed for a penetration depth not exceeding 70 meters. It is also recommended to maintain a distance of at least 3 meters from the bottom of the well.
No, the 300QJP is a clean water pump. Pumping sediment or muddy water can cause premature wear on the impeller and bearings, potentially leading to pump failure.
The standard model operates on a three-phase AC 380V, 50Hz power supply. If your site requires different voltage grades, customization is available upon request.
To prevent ice damage, drain all water from the motor cavity before winter storage. Store the unit indoors in a dry environment below 40°C, away from corrosive gases.
For optimal longevity and motor protection, the water output should be controlled between 0.7 to 1.2 times the rated flow of the specific model.
