Product Overview
Pressure boosting from 4-inch wells into holding tanks and distribution systems is the purpose of this submersible pump, serving demanding fluid transfer applications where consistent high-volume delivery is essential. The floating impeller design maintains stable hydraulic performance in groundwater containing suspended particulates.
Powered by a 415V three-phase motor rated at 1.1 kW, drawing 3.1 Amps during normal operation. Maximum flow reaches 90 L/Min with maximum head of 84 metres. The hydraulic characteristics support pressure boosting requirements effectively.
Floating stack construction handles sand concentrations up to 150 g/m³ without mechanical binding. The front wear ring works in conjunction with the floating impeller to improve abrasion resistance, while the hexagonal shaft provides effective impeller drive. An integrated metallic check valve prevents back-siphoning into the well.
Manufactured 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.
