Liyuan Solar Submersible Pump Systems
Built for off-grid or hybrid-grid operations, Liyuan Solar Submersible Pumps harness solar energy for efficient water lifting in agriculture, rural supply, livestock, and irrigation. Available in impeller and screw (helical rotor) configurations, they deliver reliable water output under varying sun conditions and well depths up to 300 meters.
Solar-Ready by Design
For over a decade, Liyuan Pump Co., Ltd. has specialized in solar pump development. Our fully integrated systems pair high-efficiency submersible pumps with MPPT solar inverters or brushless DC controllers, engineered for autonomous daily performance and water-saving precision.
✅ Water-cooled BLDC & AC motors
✅ Wide voltage range: 60–430VDC / 110–380VAC
✅ MPPT auto-tracking algorithm
✅ Options: Screw / Impeller Pump heads
