Its self-priming centrifugal arrangement is developed for stable recirculation performance across pools up to 125,000 litres.\u003c\/p\u003e\n\n\u003cp\u003eFlow handling capability reaches 580 L\/Min while discharge head extends to 18.5 m depending on hydraulic conditions. The pump operates through a single-phase 240V motor delivering 2.05 kW input power with rated operating current of 9 A. The hydraulic section is engineered to provide increased circulation capacity together with efficient head performance across larger pool systems.\u003c\/p\u003e\n\n\u003cp\u003eWater movement is maintained through an efficient impeller and diffuser arrangement developed to improve hydraulic flow behaviour and reduce pressure loss. The self-priming configuration assists restoration of circulation after temporary interruption of suction conditions, while the integrated 2.05 litre leaf basket supports debris capture before entry into the hydraulic chamber.\u003c\/p\u003e\n\n\u003cp\u003eHigh-grade engineering plastic construction contributes durability within exposed pool equipment installations and chemically treated water environments. The pump incorporates supplied 40 mm and 50 mm barrel unions to simplify installation together with drain plugs that assist easier casing drainage during maintenance procedures.
