Higher-capacity residential pool systems and larger swim spas can integrate the Davey DSF420 StarFlo where strong circulation performance and dependable self-priming operation are required for continuous filtration duty. The hydraulic arrangement is suited to filtration, solar heating, recirculation, and pool cleaning applications operating across larger residential installations.
Maximum hydraulic flow extends to approximately 470 L/Min while head capability reaches approximately 19 m depending on operating conditions. Powered through a single-phase 240V motor delivering 1.6 kW input power with rated current of 8.3 A, the DSF420 supports increased water turnover and stable circulation performance for demanding residential pool systems.
Pool water movement is maintained through a centrifugal self-priming hydraulic section developed for efficient flow delivery and dependable recirculation behaviour. A corrosion-resistant Noryl impeller supports long-term hydraulic performance within chemically treated pool environments, while the transparent strainer lid assists rapid inspection and basket access during routine maintenance. Integrated self-resetting thermal overload protection assists safeguarding the motor during elevated operating temperatures.
Manufactured using corrosion-resistant UV stabilised thermoplastic materials, the pump body is developed for long operating life within exposed outdoor pool equipment installations. The hydraulic assembly incorporates 40/50 mm barrel union connections for installation flexibility together with a totally enclosed motor configuration. Additional engineering details include a 316 stainless steel motor shaft, high-performance silicon carbide Viton mechanical seal arrangement, and drain plug access for simplified servicing procedures.
