Product Overview
This submersible pump is developed for continuous primary water supply networks from 4-inch wells, serving high-efficiency, shallow-depth fluid management duties. The floating impeller configuration supports reliable operation in groundwater containing suspended particulates.
Powered by a 415V three-phase motor rated at 0.37 kW, drawing 1.2 Amps during normal operation. Maximum flow reaches 90 L/Min with maximum head of 24 metres. The hydraulic performance supports consistent water delivery for supply networks.
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 embedded stainless steel check valve arrests the falling water column when power is cut.
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.
