Larger residential pools and swim spa circulation systems can integrate the Davey DEF430 where higher-volume water movement and dependable self-priming operation are required. The pump is suited to filtration, heating systems, spa jet operation, and in-floor cleaning duties across installations servicing pools up to 104,000 litres.
Hydraulic performance extends to 520 L/Min maximum flow with discharge head capability reaching 20.5 m under operating conditions. Operation is supplied through a single-phase 240V motor utilizing 1.61 kW input power while drawing rated current of 6.9 A. The hydraulic arrangement is configured to deliver strong recirculation performance while reducing pressure loss during pool operation.
Circulation efficiency is supported through a custom-shaped impeller and diffuser combination engineered to improve water flow and hydraulic behaviour. The self-priming centrifugal layout assists recovery of circulation after interrupted suction conditions, while the integrated 2.05 litre leaf basket supports collection of suspended debris before entering the hydraulic chamber.
Manufactured using high-grade engineering plastics, the pump body is developed for long operational life within outdoor pool equipment environments. Installation flexibility is supported through supplied 40 mm and 50 mm barrel unions, while integrated drain plugs assist simplified servicing and casing drainage. Smart Motor Protection and thermal overload protection are incorporated into the motor assembly to support reliable operating protection.
