马拉维采购需求：充电宝水泵

I'm looking for a surface solar pump with a DC power capability of around 1500 watts. The pump should be able to handle a head range between 15 to 25 meters, ensuring it can efficiently deliver water across various elevations. In terms of flow rate, I'm expecting it to operate between 20 to 25 cubic meters per hour, making it suitable for my specific requirements. Additionally, please provide details on the overall design, durability, and any available options for customization. I'd also like to know about the efficiency of the solar panel setup, as well as any warranties or after-sales support you offer. Don't hesitate to include information about pricing and lead times for delivery. Looking forward to your prompt response!
