Product Overview

The 4DSP series is a DC-powered permanent magnet variable frequency pump engineered for clean water applications, with a focus on remote areas, renewable energy integration, and eco-friendly scenarios. Developed by Yimai Zhihui, it operates on DC voltage (72V–160V), making it compatible with solar panels, batteries, and off-grid power systems—ideal for locations where AC power is unstable or unavailable.

Key Product Features

DC Voltage Compatibility: Operates on 72V–160V DC, pairing seamlessly with solar panels (common 72V/110V solar setups) and batteries for off-grid use—no AC-to-DC converters needed.

Eco-Friendly Applications: Designed for ecological governance and agricultural irrigation, minimizing carbon footprint while delivering reliable performance.

Remote Area Suitability: Durable construction resists dust and mild moisture, making it suitable for grasslands, deserts, and rural areas with harsh environmental conditions.

Energy Efficiency: Saves 30%–50% energy vs. traditional DC pumps, extending battery life in off-grid systems and reducing solar panel capacity requirements.

Scenario-Based Solutions

Ecological Governance & Reservoir Management

Small Reservoir Water Circulation: The 4DSP pump circulates water in small reservoirs or ponds, preventing stagnation, improving oxygen levels, and supporting aquatic ecosystems.

Wetland Restoration: Transports clean water to restored wetlands, ensuring consistent moisture for native plants and wildlife.

Farmland & Orchard Irrigation

Drip & Sprinkler Irrigation: The 4DSP series (e.g., 4DSP13/60-110/1500 with 13 m³/h flow) supplies water to drip or sprinkler systems in orchards and vegetable farms, ensuring uniform irrigation and reducing water waste.

Solar-Powered Irrigation: Paired with solar panels, it operates independently of the grid, ideal for remote farms without AC power access.

Grassland & Desert Water Supply

Livestock Watering: Delivers water from wells or storage tanks to grassland livestock (e.g., sheep, cattle), ensuring access to clean water in arid regions.

Desert Greening Projects: Supplies water to desert afforestation areas, supporting the growth of drought-resistant plants and combating desertification.
