Permanent Magnet Variable Frequency Circulation Pump

Cooling/Lubrication System
Used in cooling circulation systems for machine tools, injection molding machines, compressors, and other equipment. It automatically adjusts flow rate based on load changes and dynamically regulates pump power according to the cooling/heating demands of air energy units, reducing energy consumption (30%~50% more energy-efficient compared to traditional pumps).

Permanent Magnet Variable Frequency Constant Pressure Pump

Designed to resolve low water pressure in lower floors or unstable pressure in higher floors, this pump intelligently adjusts its speed to address insufficient water pressure in old residential areas or villas, ensuring constant pressure throughout the entire building. It operates quietly with noise levels as low as **40–55 dB** (compared to 70–85 dB for traditional pumps) and delivers **30%–50% energy savings** over conventional pumps.

Solar-Powered Permanent Magnet Pump

This system operates independently of the grid, directly utilizing solar energy to address water supply challenges in off-grid areas such as remote mountains, deserts, pastures, and islands. Featuring a high-efficiency, low-consumption permanent magnet motor, it achieves 20%~30% higher efficiency than traditional induction motors, delivering greater water output at the same power level.

Typical Applications
 Desert Agriculture Irrigation (e.g., Israel's Drip Irrigation Systems): Solar-powered permanent magnet pumps extract groundwater, transforming arid land into fertile oasis with over 60% water-saving efficiency.
 High-Altitude Pasture Water Supply: Provides 24/7 drinking water for livestock in areas above 3,000 meters with no electricity, eliminating the need for long-distance water transportation.
 Aquaculture Circulation Systems: Enhances oxygen supply and water circulation for shrimp and fish ponds, increasing breeding density and survival rates.
Since its founding in 2017, Zhejiang Eiiman Zhihui has rapidly risen to become an innovation leader in the industry, a modern technology enterprise that integrates research and development, production and sales.
