USB DC 5V Submersible Mini Pump – Pet Fountain LED Sensor

USB DC 5V Submersible Mini Pump for Pet Drinking Fountains

Keep your furry friend hydrated with this quiet, reliable USB-powered submersible mini water pump. Designed as a direct replacement for most pet drinking fountains, it features a built-in LED water-level indicator and automatic dry-run shutoff — giving you peace of mind around the clock.

Key Features

• Smart LED Water-Level Indicator: Blue light signals normal water levels; red light alerts you when water is running low, so your pet is never left without a fresh supply.
• Automatic Dry-Run Protection: The pump stops automatically when the water level drops too low, protecting the motor and extending product life.
• Detachable Filter Cotton: Removes hair and impurities from the water, keeping the impeller clear and the water clean for your pet.
• Ultra-Silent Operation: A built-in noise-reducing air duct combined with silicone suction cups absorbs vibration — virtually silent during use, so neither you nor your pet will be disturbed.
