The Submersible DC Solar Well Pump SS304 Impeller-4inch BLSS, manufactured by Zhejiang Baile Pump Line Co. Ltd, is an exceptional product designed to meet the needs of B2B buyers in the agro and agriculture industry. This high-quality pump offers reliable performance and efficient water transfer for various farming applications.

With a maximum flow range of 3.7 m³/h to 42 m³/h and a max head range of 20m to 154m, this submersible pump ensures a steady supply of water even in remote areas. It operates on DC voltage options of 48V, 72V, and 96V, providing flexibility and compatibility with solar power systems.

The pump features a durable 4" outer diameter, making it suitable for installation in standard-sized well casings. It offers multiple outlet diameter options of 1.25", 1.5", 2", and 3", allowing for easy connection to various plumbing systems.

One of the key advantages of this submersible pump is its MPPT (Maximum Power Point Tracking) function, which makes it 5%-10% more efficient than normal pumps. The MPPT function automatically adjusts the motor speed based on the light intensity, maximizing power utilization and ensuring optimal performance in varying solar conditions.

Moreover, the pump is equipped with an automatic on/off feature that activates when the water level reaches the lowest or highest position in the container. This ensures efficient water management and protects the pump from damage due to dry running or overflows.

The control box operates the pump automatically, responding to changes in sunlight intensity. It adjusts the motor speed, enters dormant mode when not required, and wakes up when necessary. The reliable and robust construction of the pump includes a stainless steel motor housing, outlet, and impeller, ensuring durability and resistance to corrosion.

The motor is a permanent magnet synchronous brushless motor (PMSM) with high efficiency and long-lasting performance. The pump also incorporates NSK bearings for smooth operation and extended service life.
