Spare OASE Impeller for the following pond pumps:OASE AquaMax Eco Premium 12000OASE AquaMax Eco Premium 16000We highly recommend checking for limescale build-up on the impeller shaft before replacing for a new one. Limescale can accumulate over time and this can slow or stall the rotor over time, particularly if the pump is switched off for prolonged periods. Use PumpClean or a limescale remover and soak the pump motor for 24 hours and retest.
