Air Pump Aquarium

Aquarium air pumps, also called diaphragm pumps, supply air to air stones, sponge filters, airlift filters and other air-driven equipment. The required output depends on the number of outlets, water depth, tubing length and the resistance created by air stones, valves and connected devices.

Compare airflow, number of outlets, adjustment options, power consumption and stated noise level. A deeper aquarium or several connected devices require more pressure and performance. If one pump supplies multiple lines, an air distributor allows the individual outlets to be balanced.

Airline tubing, non-return valves, air stones and manifolds may need to be ordered separately. Position the pump above the water level where possible, or install a suitable non-return valve to reduce the risk of water flowing back into the pump. Vibration can be reduced by placing the unit on a stable surface according to the manufacturer’s instructions.
