Product Overview
Fire protection reserves require water drawn from extremely deep subterranean sources, and this submersible borehole pump delivers the pressure and flow needed for reliable emergency water supply. The floating impeller configuration maintains performance in deep well applications where critical operation is essential.
Operating on 240V single-phase power, the 1.1 kW motor draws 7.6 Amps during duty. Maximum flow reaches 22.5 L/Min, with maximum head of 204 metres. The hydraulic design provides the high head characteristics required for vertical extraction from significant depths.
Floating stack construction allows the pump to handle water containing up to 150 g/m³ of suspended sand. The front wear ring works with the floating impeller to improve abrasion resistance, while the hexagonal shaft ensures effective impeller drive. A heavy-duty non-return valve is integrated within the discharge section.
Constructed with a 304 Stainless Steel outer casing and technopolymer hydraulic components. The motor adapter and discharge head are manufactured from precision-cast stainless steel. Supplied complete with external starting control equipment and thermal shrink kit for waterproof cable connections.
