Dayliff's DDPS are solar-powered peripheral surface booster pumps for small-scale water transfer where grid power is unavailable. Continuous-rated permanent-magnet brushless DC motors of 220 W (12 V) and 370 W (24 V) run at 2900 rpm, with the built-in controller providing thermal and over-voltage protection and connecting directly to the PV array via the supplied MC4 cable.

Construction is a cast-iron pump body with aluminium motor body, brass peripheral impeller and silicon-carbide mechanical seal, rated IP54 with Class B insulation, for thin, clean, non-aggressive liquids up to +40 °C. Head/flow performance is published as curves in the datasheet — the 370 W model's curve starts at roughly 31 m at zero flow.
