Expected Output: Medo LA-120A

Use this chart to estimate the output (flow) from the Medo LA-120A for a given backpressure.
For example, if you know the aeration depth of your system is 1.8 m and there are no other factors causing resistance, the backpressure of the system would be around 180 mbar.
On the graph, trace up from 180 mbar to the 50Hz line, then over to the scale on the left. At a backpressure of 180 mbar, the LA-120A would produce an estimated flow rate of 120 l/min.

  • Easy Maintenance

    It is easy to maintain Medo pumps as they are designed from the ground up to be completely serviceable by the end-user.

  • Long Life Expectancy

    Medo pumps are widely known for their incredible build quality, resulting in an ultra-long lifespan.

  • Piston Driven

    The Medo range all operate using pistons rather than diaphragms. As a result, they last for a very long time before needing a service.

Pump Details

The Medo LA-120A outputs around 120 l/min at a back pressure of 180 mbar. At this backpressure, it would consume only 130 W per hour, which is very low, making less of an impact on the environment and costing less to run.
The LA-120A operates at only 48 dB(A), which is very quiet – for reference, a quite office is about 50 dB.
The LA-120A will not produce significant noise pollution, keeping the local wildlife and your neighbours happy.
