LIS/LICPM All-Iron Solar High-Lift Low-Flow Pump

Model Interpretation:
L: Vertical/Centrifugal.
I: Intelligent/Inbuilt or DC (Li).
S: Stainless Steel or Surface.
CPM: Usually represents "Cast Iron/Stainless Steel Pump" or "Cubic Meter per hour" (high flow rate).

Core Configuration: Horizontal single-stage or double-stage centrifugal pump (some models may involve screw pump structure).
Core Differences: This series typically uses all-stainless steel or cast iron pump bodies, equipped with high-power DC brushless motors, with power usually ranging from 1HP to 5HP or even higher, making them truly "heavy-duty" pumps.
Core Working Principle: Industrial-grade centrifugal + DC brushless drive
The working logic of the LIS/LICPM series is "powerful output, stable and reliable":
Large Diameter Design: The inlet and outlet are usually 2 inches, 3 inches, or even larger, with wide flow channels, allowing water containing trace impurities to pass through without easily clogging.
DC Brushless Direct Drive (High Torque): Uses a high-performance DC brushless motor, combined with an MPPT controller, which can automatically adjust the speed according to the light intensity. At noon with sufficient sunlight, it can deliver astonishing flow rates and pressure.
Wide Voltage Operation: This series usually supports a wide voltage input range (such as DC 48V-380V), which can adapt to fluctuations in solar panel voltage and is less likely to be damaged due to unstable voltage.
Core Features: High power, corrosion resistance, wear resistance

Feature Detailed Description
Ultra-high Flow Rate & High Head  Core advantage. The flow rate of this series can usually reach tens of cubic meters per hour (e.g., 10-50 tons/hour), and the head can reach tens of meters. It can easily meet the irrigation needs of large areas of farmland.
All-metal Material The pump body is usually made of 304 stainless steel or cast iron, which is corrosion-resistant and wear-resistant, with a service life of more than 10 years. Compared with plastic pumps, it is more suitable for complex outdoor working conditions.
Low Noise & High Efficiency Due to the brushless motor, the operating noise is much lower than traditional brushed motors or diesel engines. At the same time, the brushless motor is highly efficient, maximizing the utilization of solar energy.
Multifunctional Design: It can be used as both a clean water pump and a sewage pump (some models), offering strong adaptability.

Typical Application Scenarios
The LIS/LICPM series is the preferred equipment for large farms, water conservancy projects, and industrial applications:
Large-scale agricultural irrigation:
Suitable for farms with flat terrain and high water demand. It can quickly transport water from rivers or ponds to the fields.
Drought relief and flood control/drainage:
During the rainy season, it can quickly drain accumulated water from low-lying areas; during the dry season, it can quickly draw water from deep water sources.
Large fish pond/shrimp pond circulation:
Used for water exchange and oxygenation circulation in large aquaculture ponds.
Industrial/construction site drainage:
Suitable for industrial scenarios or construction sites that require rapid transfer of large amounts of liquid.

Selection and Usage Recommendations:
Power Matching:
The LIS/LICPM series has high power and requires a sufficiently large solar panel array and an industrial-grade MPPT controller. When selecting a model, please ensure that the peak voltage and power of the solar panels meet the pump's starting requirements.
Anti-clogging:
Although the flow channel is large, to protect the impeller, it is recommended to install a filter screen at the inlet to prevent large debris from being sucked in.
Installation Environment:
This series is usually large and heavy, requiring a stable installation foundation. If used outdoors, it is recommended to take rain and sun protection measures.

The LIS/LICPM series is the "heavy-duty equipment" among solar ground pumps. If you need to "move a massive amount of water in a short time," or "cope with harsh outdoor working conditions," then the LIS/LICPM series is the irreplaceable best choice. It is a powerful assistant for large-scale agricultural production and industrial applications.
