  • Description

    The J self-priming centrifugal pumps are used in applications requiring a fast priming capacity from demanding suction heights combined with the ability to transfer and manage polluted, waste and abrasive fluids with suspended solids.

    The system features an inspectable pump casing, which also acts as a water tank allowing for early quick priming without auxiliary systems, simplifying system management and reducing maintenance times.
