Product Overview
Large-scale water supply operations retrieving fluid from exceptionally deep 4-inch boreholes are the domain of this submersible pump. It serves municipal and industrial water extraction duties where consistent flow and high head are essential, with a floating impeller configuration that supports reliable long-term operation.
Wired for 415V three-phase power, the 1.1 kW motor draws 3.1 Amps during normal operation. Maximum flow reaches 22.5 L/Min with maximum head of 204 metres. The hydraulic performance characteristics support deep well installations requiring significant lift.
Floating internal design permits the pump to handle water 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 ensures effective impeller drive. A precisely engineered non-return valve locks the vertical water column on shutdown.
Constructed with a 304 Stainless Steel casing and technopolymer hydraulic components. The motor adapter and discharge head are precision-cast stainless steel. This complete three-phase model includes a heavy-duty heatshrink kit for waterproof deep-water connections.
