SANDPIPER HDF1 Metallic Pump

SANDPIPER HDF1 Metallic Pump is used for sludge, slurry, grit and media containing larger or irregular solids. It is relevant for operators that need dependable liquid transfer while managing media compatibility, suction conditions, solids behaviour, pressure requirements and maintenance access. The model should be selected against the actual duty point rather than by connection size alone. The model uses flap-valve liquid path that reduces blockage risk. This gives the pump the dry-running, self-priming and deadhead-tolerant operating characteristics associated with SANDPIPER AODD technology, while allowing model-specific wetted materials and elastomers to be matched to the process. Published performance includes up to 265 l/min and up to 8.6 bar. Final wetted materials, diaphragm, valve and seal configuration must be checked against the actual fluid, temperature and duty. AxFlow supplies the model and supports selection against the actual duty point, fluid properties and installation conditions. For maintenance teams, the practical value is serviceable construction and replaceable wear components. Correct configuration and planned replacement of diaphragms, valves and air-side wear parts help reduce unplanned stoppages, support process continuity and control total lifecycle cost.
