Dayliff's DSD series are multistage centrifugal submersible borehole pumps for domestic and small-scale water supply, with AISI 304 stainless-steel housing, shaft and coupling and sand-handling plastic impellers (max. sand content 0.25%). The sealed, liquid-cooled 2-pole asynchronous motor is IP68 rated at 2850 rpm, and each pump ships complete with 30 m of cable and a control box.

The datasheet covers 0.37–1.1 kW (0.5–1.5 HP) single-phase models with 1¼″ outlet, for boreholes of 110 mm diameter and larger and immersion to 80 m; head/flow performance is published as curves in the datasheet. Solarised as DSD KITs, the pumps are matched with Dayliff's Sunverter controllers — the combination this catalog cross-links below.
