A Constant Supply of Fresh, Flowing Water for Your Beloved Pet The Replacement Pump is a high‑quality accessory designed specifically for pet water fountains. It is perfectly compatible with most 2.2L (74 oz), 3.2L (108 oz), 4L (135 oz), and 7L (236 oz) stainless steel cat and dog fountains. Please check your original pump model before purchasing to ensure a perfect fit. Why Choose the our Replacement Pump? Extremely Quiet – Day and Night Operating noise is below 20 dB – virtually silent. Whether placed in the bedroom, living room, or study, it won’t disturb your work, rest, or your pet’s sleep. Healthy Hydration Starts with “Moving Water” Studies show that pets are naturally attracted to flowing water. The pump continuously circulates water from the bottom of the tank to the top of the fountain, creating a fresh, oxygen‑rich stream. This not only increases oxygen content but also stimulates your pet’s drinking instinct, helping them develop the healthy habit of drinking more water. Safety First – Thoughtfully Engineered With DC 5V low‑voltage power (1.5W ultra‑low power consumption), the risk of electric shock is eliminated. The IPX8 waterproof rating means the pump can be fully submerged and operate reliably for extended periods. Safe for both cats and dogs. Easy Maintenance, Long‑Lasting Durability Say goodbye to complicated disassembly! The detachable structure makes cleaning simple. We recommend a routine clean every 1‑2 weeks to remove hair and debris from inside the pump, keeping it efficient and greatly extending its lifespan. USB Power – Use It Anywhere The standard USB interface works with adapters, power banks, laptops, and more. When traveling, just bring a power bank – your pet can enjoy fresh, flowing water wherever you go. Package Contents Replacement Pump × 1 (USB power adapter not included)
