The 800L/H Centrifugal Water Heat Pump (12V) is a compact and efficient pump designed for various applications. Here are some key points about this pump: Usage and Applications: The pump is suitable for transferring water in hot water applications, such as solar geysers and camping showers. It can handle water temperatures up to 60℃. The pump is versatile and can be used in different industries and settings, including the aquarium industry, automotive industry, food industry, household appliances industry, chemical industry, and mechanical systems. Power Source: The pump operates on a DC 12V power supply. It can be powered by various sources, including batteries, solar panels, or a 12V DC power supply. Note that the power source is not provided with the pump, and you need to connect your own power supply to the red ( ) and black (-) wires. Performance: The pump is capable of displacing 800 liters of water per hour (800L/H) and has a maximum lift (head) of 4 meters. The flow channel characteristic is one side in and one side out, and it has a suction caliber of 17mm and an output caliber of 10mm. Efficiency: Despite its small size, the pump is designed to be highly efficient due to its DC motor. This efficiency allows it to deliver a significant flow of water while maintaining a compact form factor. Noise Level: The pump operates quietly, with a noise level of less than or equal to 35 dB. Material: The pump is constructed from engineering plastic, which makes it durable and suitable for various applications, including those involving liquids at different temperatures. Usage Guidelines: To achieve the maximum output and efficiency, it's recommended to power the pump with a minimum 20W 12V DC power source. However, it can still operate at lower power levels, although its performance may be reduced. Maintenance: Regular cleaning is important to ensure optimal pump function. Grit and debris should be removed to prevent clogs or reduced efficiency. Overall, this pump is designed to be versatile, efficient, and suitable for a wide range of applications where water transfer is required.
