Product Overview
Heavy-duty pressure boosting networks extracting water from extreme depths within 4-inch boreholes are the primary application for this submersible pump, serving demanding industrial applications where reliable high-volume delivery is essential. The floating impeller configuration supports continuous operation in water containing suspended solids.
Powered by a 415V three-phase motor rated at 4 kW, drawing 9.8 Amps during normal operation. Maximum flow reaches 90 L/Min with maximum head of 288 metres. The hydraulic performance supports demanding pressure boosting 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 robust metallic check valve locks the descending water column.
Manufactured with a 304 Stainless Steel casing and technopolymer hydraulic components. The discharge head is precision-cast stainless steel. Supplied with an industrial thermal shrink kit for waterproof underwater electrical splices.
