The Aquaforce sets high performance and efficiency benchmarks in flow rates and head heights. The range of Aquaforce filter and waterfall pumps have been developed to be tough, trouble free and efficient. Self Cooling System – the motors feature a water-cooling system, which ensures that the pumps are kept at a constant temperature and reduce the risk of overheating. Ceramic Bearings – maximise pump life and along with thrust washers ensure the motors are ultra reliable. Fish Protection System – all Aquaforce pumps include a removable Fish Protection System that allows you to reduce the inlet from 6mm/10mm to 2mm, to prevent fish getting into the cage. Conical Impeller – maximises performance. Carry Handle – integral carrying handle for easy lifting in and out of the pond.
