Transform Your Pond's Ecosystem
With its powerful 3500 LPH flow capacity and 3.1 meter head height, this system moves water more effectively than standard fountain pumps. The high-volume flow creates natural circulation patterns that:
Oxygenation & Water Quality
Breaks surface tension for optimal gas exchange
Distributes oxygen evenly through water column
Prevents thermal stratification in deep ponds
Reduces algae-friendly stagnant zones
Installation Flexibility
Side-mounted for circular current patterns
Subsurface angled placement for surface agitation
25 / 32 / 38 mm tubing ready for waterfall creations
5m cable allows optimal solar panel positioning
Precision Water Movement Engineering
The system's 70W monocrystalline solar array delivers consistent power to move 3500 liters per hour at low elevations, maintaining strong flow even at the maximum 3.1 meter head height - perfect for:
Cascade & Waterfall Creation
Utilize the included 38mm tubing to:
Build multi-tiered cascades up to 3.1m high
Create dramatic waterfall features
Design natural-looking stream flows
Pond Circulation Systems
Strategic placement achieves:
Complete water turnover every 2-3 hours
Dead zone elimination in corners
Uniform temperature distribution
Optimal conditions for aquatic life
Professional-Grade Components
This system combines commercial-grade solar technology with industrial water movement engineering. The dual 35W monocrystalline panels deliver reliable power to the high-efficiency DC brushless pump, while the included 38mm tubing connection and dry-run protection ensure professional installation results. Every component is designed for continuous outdoor operation and easy integration into existing pond ecosystems.

Pond Sizing & Flow Recommendations
Proper sizing ensures your water movement system works effectively without being overpowering. As a general principle, we recommend achieving complete water turnover every 1-2 hours for optimal oxygenation and circulation. The 3500 LPH flow capacity makes this system ideal for ponds between 1,000-3,000 liters when used for circulation, or smaller volumes when creating cascades. Consider your aquatic life, pond shape, and desired current strength when positioning the pump - our experience shows side-mounted installations create the most effective
Ornamental Ponds
500-1000L: Complete turnover every 10-20 minutes
1000-2000L: Full circulation every 30-40 minutes
2000-3000L: Effective current for medium fish stocks
Waterfall Systems
0-1m height: 2500-3500 LPH flow
1-2m height: 1500-2500 LPH flow
2-3m height: 500-1500 LPH flow

Key Observations: 1. Direct solar operation delivers significantly higher max flow rates. 2. Battery mode offers reduced flow rates at higher heights. 3. Estimates smooth out gaps for better clarity.
Our pump systems are designed for efficient, year-round operation, but perform best during spring and summer. Follow this guide for proper setup, seasonal adjustments, and maintenance to maximize performance and longevity.
Discover the operational principles and realistic performance expectations of your energy-efficient water pump system throughout the seasons. This guide helps you understand your system's capabilities and how to maximize its potential.
1. Operating Principles
Energy Collection
The panel captures sunlight and converts it to electrical energy
Energy powers the pump directly or charges the battery (in backup models)
System activation depends on light intensity and system type
Performance varies significantly with weather conditions
System Types
Direct Systems: Function only with sufficient direct sunlight
Battery-Backed Systems: Store energy for more consistent operation
Hybrid Systems: Combine immediate operation with energy storage
Each type offers different benefits based on your specific needs
2. Realistic Performance Expectations
Direct Systems Performance
Operation strictly dependent on available sunlight
Flow varies continuously with passing clouds
May start and stop multiple times on partly cloudy days
Strongest performance during midday hours with direct sun
No operation during evening or heavily overcast conditions
Battery-Backed Systems Performance
More consistent operation throughout the day
Continues running during brief cloudy periods
Provides operation after sunset (typically 1-8 hours depending on model)
Maintains steadier flow rate regardless of minor light variations
May include adjustable flow settings and timer functions
3. Seasonal Performance
Summer Performance (May to August)
Peak performance period for all system types
Direct Systems: Operation possible from early morning to evening on clear days
Battery Systems: Consistent daytime operation plus evening hours
Maximum flow rates achieved during direct midday sun
