Product Overview

The 3DSP series is a high-head DC permanent magnet variable frequency pump designed to solve water supply challenges in elevated, remote, or high-demand settings. Developed by Yimai Zhihui, it combines exceptional max head (up to 180 m) with DC voltage compatibility (48V–160V), making it perfect for high-rise buildings, deep wells, and remote areas where water needs to be pumped over long distances or to great heights.

Key Product Features

Exceptional High Head: With max heads up to 180 m, the 3DSP series outperforms most DC pumps, easily handling high-rise buildings (20+ floors) and deep well extraction (up to 80m depth with proper setup).

Wide DC Voltage Range: Operates on 48V–160V DC, compatible with various power sources (solar panels, batteries, DC generators) for on-grid and off-grid use.

Durable for Harsh Conditions: Reinforced housing resists corrosion and impact, making it suitable for remote areas with extreme temperatures (–10℃ to 40℃) and dust.

Intelligent Pressure Control: Automatically adjusts speed to maintain stable pressure, even when pumping to high floors—no more weak showers on upper levels.

Scenario-Based Solutions

High-Rise Building Water Supply

Mid-Rise Buildings (10–15 Floors): Models like 3DSP5.5/100-72/1100 (max head 100 m) provide consistent water pressure to all floors, eliminating pressure drops on upper levels.

High-Rise Buildings (15+ Floors): The 3DSP3.8/180-110/1500 (max head 180 m) ensures reliable water supply to penthouses and top-floor apartments, even in tall residential towers.

Remote Area Deep Well Extraction

For rural or mountainous areas with deep wells (50m–80m):

The 3DSP series (e.g., 3DSP5.5/140-110/1500) extracts water from deep wells and pressurizes it for domestic use, replacing inefficient manual or low-head pumps.

Paired with solar panels, it operates off-grid, ensuring water access in areas without AC power.

Large Villa & Luxury Home Water Supply

Multi-Level Villas with Elevated Tanks: The 3DSP pump boosts water from ground-level wells to rooftop tanks (even 10+ meters high) and maintains pressure for multiple bathrooms, pools, and gardens.

Outdoor Water Features: Powers large fountains or waterfalls in luxury villas, using high head to circulate water to elevated feature components.

Industrial Circulation with Elevated Requirements

Small-Scale Mining or Construction: Circulates cooling water to elevated machinery (e.g., construction cranes, small mining equipment) in remote job sites, preventing overheating.

Water Tower Refilling: Refills elevated water towers in rural communities, ensuring consistent water supply to nearby homes and businesses.
