SANDPIPER HD20F Non Metallic Pump

SANDPIPER HD20F Non Metallic Pump is used for sludge, wastewater, grit, slurry and media with larger or irregular solids. It is relevant for plants that need dependable liquid transfer while managing media compatibility, solids behaviour, suction conditions, air consumption and maintenance access. The model should be selected against the actual duty point and the full pumped-fluid profile. The model uses flap-valve liquid path that helps reduce blockage risk when solids are present. This gives the pump the dry-running and self-priming advantages associated with AODD technology, while allowing the wetted materials, diaphragms, balls, seats, flaps or seals to be matched to the process liquid. Its final configuration should be selected based on liquid chemistry, solids content, viscosity and the required duty point. AxFlow can support checks for port size, elastomer selection, material compatibility, solids tolerance, air supply and installation conditions before a final selection is made. For maintenance teams, the practical value is improved process continuity in applications where ball-valve pumps can be vulnerable to clogging. Correct model selection and timely replacement of wear parts help reduce unplanned stoppages, simplify service planning and support a lower total cost of ownership over the pump lifecycle.
