The 135QJP Series Fountain Submersible Pump represents a pinnacle of engineering efficiency, specifically developed for high-performance water lifting and fountain applications. Featuring a motor core crafted from premium cold-rolled silicon steel, this series ensures exceptional magnetic conductivity and seamless, heat-free starts. By replacing traditional ball bearings with unique water-lubricated alloy copper sleeves at the rotor ends, the QJP series effectively eliminates rust and wear caused by lubrication failure, significantly extending the operational lifespan of the motor.
Engineered for reliability in demanding environments, these pumps utilize a water-filled wet submersible three-phase asynchronous motor. The integration of a pressure-regulating film manages internal expansion and contraction caused by temperature changes, while a sophisticated sand-prevention structure—featuring double oil seals and a dedicated sand ring—protects the motor from contaminants. Whether for deep well water intake or large-scale agricultural irrigation, the 135QJP series delivers a stable, high-efficiency solution with a professional CAD-optimized structure.

Management Platforms
Installation Readiness
Pre-installation checks include wellbore diameter measurement and clean water verification to prevent damage.
Electrical Safety
Requires distribution boxes with short-circuit, phase loss, and overload protection for total motor safety.
Waterproofing Control
Strict multi-layer high-pressure insulation taping for cable joints to ensure 100% water-tightness.
Operational Monitoring
Regular monitoring of voltage and current to ensure stability within 10% of rated parameters.
Winter Maintenance
Mandatory draining of the motor cavity during freezing temperatures to prevent structural cracking.
Periodic Overhaul
Recommended dismantling and wear-part replacement every operating year to maintain peak efficiency.

Frequently Asked Questions
It is ideal for deep well water intake, high-rise building water supply, agricultural and garden irrigation, river water intake, and domestic water systems.
Ensure the pump is completely immersed in water before operation, use an external overload protection device, and avoid running the pump in no-load conditions.
No, it is strictly a clean water pump. Extracting mud or silt is prohibited as it can cause premature damage to the bearings and impellers.
Unlike standard ball bearings, these sleeves eliminate the need for oil and prevent rust and wear, which is critical for longevity in submerged environments.
You must drain all water from the motor cavity to prevent freezing, which could otherwise expand and damage the motor casing.
The maximum diving depth is 70 meters, and it should be installed vertically with at least 3 meters of clearance from the bottom of the well.
