Product Overview
Heavy sprinkler irrigation duties from deep underground cisterns and boreholes are the focus of this submersible pump, serving agricultural applications where reliable high-flow, high-head delivery is essential. The floating impeller design maintains performance in groundwater containing suspended solids.
Powered by a 415V three-phase motor rated at 2.2 kW, drawing 6.1 Amps during normal operation. Maximum flow reaches 90 L/Min with maximum head of 162 metres. The hydraulic performance supports demanding sprinkler irrigation requirements effectively.
Floating stack construction processes liquids containing up to 150 g/m³ of suspended sand. The front wear ring works in conjunction with the floating impeller to improve abrasion resistance, while the hexagonal shaft provides effective impeller drive. A heavy-duty non-return valve prevents reverse flow of the pressurised column.
Constructed with a 304 Stainless Steel casing and technopolymer hydraulic components. The discharge head is precision-cast stainless steel. Supplied with an industrial heatshrink kit for waterproof electrical splices.
