Expected Output: JDK-100AL

Use this chart to estimate the output (flow) expected from the JDK-S-100AL (AKA JDK-100AL) for a given backpressure.
For example, if you know the aeration depth of your system is 2m and there are no other factors causing resistance, the backpressure of the system would be around 200 mbar. On the graph, trace up from 200 mbar to the JDK-100 line, then over to the scale on the right. At a backpressure of 200 mbar, the JDK-100AL would produce an estimated flow rate of 95l/min.

  • Use Less Energy

    The JDK models feature less energy consumption (up to 30% depending on the application) and fewer overall dimensions (also by about 30%) compared to the SLL and EL series. This makes the class not only more compact but also lighter.

  • Long Life Expectancy

    Motor and pump parts are combined in one single construction. The compact and light construction form and the simple mechanism guarantee a long and reliable period of operation.

  • Energy Efficient

    The principle of electromagnetic oscillation, which practically has no mechanical friction, minimises power consumption and provides a high degree of efficiency.

Pump Details

The JDK-S-100AL (JDK-100AL) outputs around 100l/min at a back pressure of 200 mbar. At this backpressure, it would consume only 75W per hour, which is very low, making less of an impact on the environment and costing less to run.
The JDK-100AL operates at only 42 dB(A), which is very quiet – for reference, a refrigerator is about 40 dB. The JDK-100AL will not produce significant noise pollution, keeping the local wildlife and your neighbours happy.

  • Low Noise Level

    The soundproof casing and the muffler integrated into the tank base reduce operating noise.

  • Low Vibration

    Motor and pump parts are separated by a vibration-isolating rubber, so only low vibration consists.

  • Completely oil-free

    The oil-free operation guarantees a dry and unadulterated airflow.

Spares Guide

All the spares you will ever need for your JDK-100AL are typically immediately available and will be for a long time to come. For reference, the spare parts for the JDK-100's predecessor (EL-100) are still widely available even though it has been many years since the EL range became discontinued.

  • Weatherproof

    The SLL, EL, and JDK series are rainproof and weatherproof. However, they should not be exposed to direct sunlight, rain, or snow.

  • Pulsation-free airflow

    Specially formed pump chambers and the muffler integrated into the tank base provide an airflow, which is practically pulsation-free.

  • Universal service kits

    For each model series, service kits are available. They are vacuum-packed in aluminium foil for better and longer life/ storage.
