Higher-capacity swimming pool systems operating with extended filtration cycles, solar heating loops, and automated cleaning equipment require stable water movement with controlled energy usage throughout daily operation. The Davey PM400BT is suited to larger in-ground and above-ground pool installations up to 110,000 litres where adjustable circulation management and quieter continuous-duty performance are important across varying operating conditions.
Ten variable speed settings allow circulation output to be matched against changing hydraulic demand while helping reduce unnecessary power consumption during lower-flow operation. The pump operates up to 1650W input power and delivers flow performance from 146 L/Min at 1.2 m head through to 380 L/Min at 8 m head at maximum speed setting. Progressive speed adjustment assists with maintaining balanced circulation across filtration systems, heating equipment, and high-demand pool cleaning circuits.
Controlled speed regulation supports smoother hydraulic behaviour during filtration turnover, backwash operation, and automated cleaning cycles without excessive turbulence through connected pool equipment. The integrated 4.5 litre leaf basket assists with capturing larger debris before entering the circulation system, helping maintain cleaner flow conditions and reducing interruption during longer operating periods.
A water-cooled motor configuration helps minimise operational noise and vibration transfer during continuous service operation. Bluetooth connectivity enables smartphone-based scheduling and speed adjustment directly from compatible mobile devices, while integrated loss-of-prime protection provides additional safeguarding during interrupted suction conditions. Multi-fit 40 mm and 50 mm barrel union compatibility also assists with retrofit installation into existing pool circulation systems.
