    Compact design
    Compact design created by the combination of the motor with the factory matched direct drive wrap around impeller hub.

    Corrosion resistance
    Mounting plate, motor support and finger proof guard protected by cataforesis primer and black polyester paint finish.
    Stainless steel screws.

    Terminal box
    Wiring terminal box with cable gland PG-11.

    Impeller dynamically balanced
    Impellers are dynamically balanced, according to ISO 1940 standard, giving vibration free operation.

    Manufacturing variations
    Multiple manufacturing variations, depending on the type of installation and use conditions.

    Configuration for models � 800 to 1000
    Special design of motor over impeller, which provides compactness and tightness
