Cast aluminum pump body with an electrostatic spray finish for durable, rustresistant performance. The finish provides longlasting protection in damp environments while keeping the pump body lightweight. Water inlet and priming Allcopper water inlet construction ensures reliable material compatibility and durability. Before first use, fill the pump with clean water to prime the system and ensure smooth operation. Cooling and noise control Cooling fan delivers efficient heat dissipation to help maintain steady performance. The design supports stable running conditions and contributes to lower operating noise during use. Impeller and suction Allcopper doubleface impeller delivers strong suction, supporting effective water transfer and circulation for typical smalltomedium flow applications. Key benefits Durable, rustresistant pump body with a corrosionresistant finish Reliable copper components for longevity and dependable water handling Efficient cooling and reduced noise for smoother operation Strong suction from a copper doubleface impeller for effective pumping Recommended uses Aquarium or terrarium water circulation and transfer to prevent stagnation Hydroponics or small garden irrigation systems requiring reliable water flow Small fountains, ponds, or decorative water features that need steady suction and quiet operation Notes Use only with clean water; prime the pump with water before operating Ensure appropriate matching of the pump to your system's flow and head requirements based on your setup This description preserves the original pump's material composition, function, and key components (cast aluminum body, copper water inlet, cooling fan, and allcopper doubleface impeller) while presenting clear, customerfocused benefits and practical use scenarios.
