Model Interpretation:
L: Vertical/Centrifugal.
I: Intelligent/Inbuilt or DC (Li).
Q: Submersible (Qian Shui).
D: Single-phase (Dan Xiang) or general code.
X: Small (Xiao Xing) or Portable (Xie Dai).
Core Form: Small single-stage or multi-stage DC brushless submersible pump.
Core Differences: This series is compact and lightweight, usually featuring a full stainless steel or powder-coated casing, designed specifically for shallow water submersible use.
Core Working Principle: Submersible centrifugal + DC brushless drive
The working logic of the LIQDX series is "plug and play, pump on demand":
Submersible operation: The pump body is completely immersed in water, using water pressure to assist in water intake, completely solving the "suction head limitation" problem of traditional surface pumps (as long as the water can cover the pump body).
DC brushless direct drive: Using an electronically commutated brushless motor, it eliminates traditional carbon brushes, resulting in extremely long life, very low noise, and much higher efficiency than ordinary AC motors.
MPPT intelligent control: When paired with a solar panel, it can automatically track the maximum power point. High speed and large flow under strong sunlight; low speed and small flow under weak sunlight.
Core Features: Compact and portable, all stainless steel, quiet operation
Feature Detailed Description
Compact size and light weight Core advantage. Compared with the industrial-grade LSG series, the LIQDX series is very lightweight and can be lifted with one hand. It is very suitable for scenarios requiring frequent movement.
All stainless steel material Usually uses 304 stainless steel pump body and impeller, corrosion-resistant and rust-proof, suitable for pumping clean water and slightly turbid water, ensuring water quality.
Quiet operation Due to the brushless motor and underwater operation, the noise is very low, unlike old-fashioned brushed motors that produce harsh noise and sparks.
High cost-effectiveness Simple structure, affordable price, making it the entry-level choice for the solar submersible pump field.
Typical Application Scenarios
The LIQDX series is the ideal equipment for home users, small farms, and landscaping:
Home/Yard Water Supply:
Used for drawing domestic water and washing water from shallow wells, cisterns, or ponds.
Garden/Vegetable Garden Irrigation:
Used for mobile irrigation of small vegetable gardens and orchards, drawing water from nearby ditches or ponds.
Fish Pond/Fountain Circulation:
Used for water circulation, filtration, and oxygenation of small ornamental fish ponds.
Emergency Drainage/Flood Control:
Used for draining accumulated water from basements, foundation pits, and puddles – simply drop it in wherever there's water.
Selection and Usage Recommendations
Submersion Depth Limitation:
As a small submersible pump, its submersion depth is usually limited (generally not exceeding 5-10 meters). If the well is very deep, please use a professional deep well pump (such as the LSG series).
Strictly Prohibited Dry Running:
The pump body must be completely submerged in water during operation. If the water level drops and the pump body is exposed to the surface, motor heat dissipation will be hindered, easily leading to motor burnout.
Anti-Entanglement:
Due to its small size and limited motor heat dissipation area, it is recommended not to pump sewage containing a large amount of long fibers (such as aquatic plants and hair) to avoid entanglement of the impeller and overheating.
The LIQDX series is the "portable tool" among solar water pumps. It's not as large and professional as the LSG series, nor does it pursue high flow rates like the LHF series, but it is flexible, convenient, and durable. If you simply need a solar pump that you can "throw into the water and use" to solve water problems for your home or small plot of land, the LIQDX series is the most cost-effective choice.
