This pump features a high-precision, wear-resistant, and corrosion-resistant brown ceramic shaft that has a significantly longer service life and produces quieter operation compared to regular ceramic shafts. This pump features three modes: 20-speed constant current speed regulation mode, wave making mode, and feeding mode. It utilizes sine wave technology for ultra-quiet operation and a low-voltage DC power supply for safety and leak-proofing. Additionally, the pump includes a screwless design, making it more environmentally friendly. Suitable for use in both freshwater and saltwater.
