The Pentax 3S 3-15 is a compact, high-efficiency 3" multistage submersible borehole pump engineered for clean water applications including domestic water rising, pressure boosting, rainwater harvesting and small-scale irrigation. Designed by Pentax for reliable long-term operation, this model balances compact dimensions with strong hydraulic performance and corrosion-resistant construction.

Key performance highlights include a 0.33 kW motor rated for 230V single-phase operation, a constant nominal flow of approximately 45 L/min and a maximum head near 46 metres (model 3-15). The pump features a 1" female outlet, integrated non-return valve in the discharge head, and a 1.5 m cable fly-lead — the 230V units are supplied complete with the required overload/capacitor box for easy electrical connection. These specifications make the 3S 3-15 suitable for medium-lift domestic and light commercial installations where compact, reliable submersible performance is required.
