What kind of water pump is used in pet drinking fountains?
The water pump used inside the pet water dispenser is usually a mini DC water pump, which has low voltage (such as 5V~12V) and brushless characteristics, and is suitable for use in small electrical equipment. They can work continuously and stably to provide circulating filtration and continuous water supply for the pet water dispenser.
This type of water pump is generally designed to be silent to reduce the impact of noise on pets and residents. In addition, the durability and reliability of the water pump are also very important to ensure that the pet water dispenser can operate stably for a long time and provide fresh and clean drinking water for pets.
