An aquarium water pump is a device that provides power to an aquarium by transferring water from one location to another to maintain the circulation and filtration of water flow. Here are some introductions about aquarium pumps:

Types: There are various types of aquarium water pumps, including submersible pumps, vertical pumps, centrifugal pumps, etc. Different types of pumps have different application scenarios and advantages and disadvantages, which need to be selected based on specific needs.

Flow and head: Flow is the hourly displacement of the water pump, expressed in liters per hour (L/h), while head is the height at which the water pump can lift water, expressed in meters (m). According to actual needs, it is necessary to choose a water pump with appropriate flow rate and head.

Power and size: Power is the electrical energy consumed by the water pump, in watts (W), while size is the overall size of the water pump, in millimeters (mm). The appropriate power and size need to be selected based on installation space and energy consumption requirements.

Filtering effect: Some aquarium pumps are also equipped with filters, which can filter out impurities and harmful substances in the water and keep the water clean.

In general, when selecting an aquarium water pump, it is necessary to consider various factors such as flow rate, head, power, size, and filtration effect, combined with actual needs, to ensure its normal operation and maintain the ecological balance of the aquarium.
