3-inch DC Solar Centrifugal Pump ARL-4SPN4-3P 600W

3-inch DC Solar Centrifugal Pump ARL-4SPN4-3P 600W

The 3-inch DC Solar Centrifugal Pump ARL-4SPN4-3P 600W is a high-performance 3-inch DC solar centrifugal pump engineered for efficient water transfer. It features a 600W BLDC motor with an integrated internal controller, capable of delivering a maximum head of 43 meters and a maximum flow rate of 8.1 cubic meters per hour. Constructed with a durable stainless steel 304 pump body and an encapsulated water-filled motor, this system ensures longevity and prevents water contamination. The pump package includes essential accessories and advanced protective functions for reliable and extended operation.

Key Features:

• High-Efficiency BLDC Motor: Equipped with a 600W Permanent Magnet Synchronous Motor (PMSM) made of AISI 304, offering a motor efficiency of up to 85% and a system efficiency of Max. 98%.
• Integrated Internal Controller: Features an internal controller with an impressive MPPT efficiency of Max. 98%, rated IP65 for robust performance.
• Durable Stainless Steel Construction: The pump body is crafted from Stainless Steel 304, and the motor material is AISI 304, ensuring high resistance to corrosion and wear. AISI 316 is available as an optional material.
• Comprehensive Protection System: Includes advanced safeguards against dry-run (eliminating the need for an external float sensor), reverse polarity, phase loss, over-voltage, low-voltage, over-current, over-load, over-power, over-temperature, and motor stall.
• Encapsulated Water-Filled Motor: Designed to prevent any potential water pollution, making it suitable for potable water applications.
• Soft Start Functionality: Gradually increases pump speed upon startup, extending the lifespan of the motor and system components.
• Thrust Bearing System: Enhances the motor’s stability and durability during operation.
• Real-time Performance Display: Provides immediate feedback on voltage, current, power, and speed.
• DC Power Only: Optimized for direct current power sources, making it ideal for solar power integration.
• Inclusive Accessories: Comes complete with a 1.5m cable, the MPPT-enabled pump controller, an electric float switch for water tank level control, and various tapes (waterproof adhesive, PVC electrical adhesive, PTFE) for convenient installation.
