Product Overview
This submersible pump is designed to handle sprinkler irrigation duties from deep underground cisterns and narrow boreholes. It extracts groundwater where reliable flow delivery is essential for agricultural and domestic water systems. The floating impeller design helps maintain performance even when handling water containing suspended solids.
Powered by a 240V single-phase motor rated at 0.55 kW, the unit draws 4.3 Amps during operation. Maximum flow is 22.5 L/Min, while maximum head reaches 105 metres. The Hydraulic performance provides consistent pressure delivery across the operating duty range for irrigation networks.
Floating stack construction permits the passage of sand concentrations up to 150 g/m³ without binding. The front wear ring works with the floating impeller to improve abrasion resistance, while the hexagonal shaft transmits motor torque directly to the impeller stages. A built-in check valve secures the system against backflow.
Built with a 304 Stainless Steel outer casing and technopolymer hydraulic components for corrosion resistance. The motor adapter and discharge head are precision-cast stainless steel. Supplied complete with external starting control equipment and thermal shrink kit for waterproof cable connections.
