Motor & Power Source: It uses a brushless DC motor (≈ 500 W) that can run directly from solar panels or a suitably rated DC battery setup.
Lift Capacity (Head): Can lift water up to 55 meters — meaning if your borehole/well is deep, or if you need to pump water high to an elevated tank, such a pump can handle the vertical distance (within its limits).
Flow Rate / Output: For many 55 m DC pumps the flow rate is moderate — for example ~ 3.5 m3/hour (≈ 3,500 litres per hour) for the Shiyuan pump at reasonable head.
Construction & Durability: Many are built with stainless steel or corrosion‐resistant materials, suitable for borehole/well water (provided the water is relatively clean, not heavily silted or abrasive).
Controller / Electronics: Because it’s DC and often solar‐compatible, such pumps include a controller that regulates.
