Impeller for Aquarius Universal ECO 4000

Genuine OASE spare impeller for the Aquarius Universal Eco 4000 Pond Pump.  Before purchasing a new impeller, check that limescale build-up is not the cause of the pump fault.  Calcium deposits can cause the rotor to stall and this can be dissolved easily by submersing the pump in a bucket of kettle descaler for several hours or with the use of the OASE PumpClean cleaning solution.
