Product Overview
Pressure boosting scenarios from 4-inch boreholes into distribution grids are effectively managed by this submersible pump, which provides high-volume water delivery for commercial systems where reliable boosting is essential. The floating impeller configuration supports continuous operation in groundwater containing suspended solids.
Connected to a 240V single-phase supply, the 2.2 kW motor draws 14.4 Amps during normal operation. Maximum flow reaches 90 L/Min with maximum head of 162 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 heavy-duty non-return valve is pre-installed at the outlet.
Constructed with a 304 Stainless Steel casing and technopolymer hydraulic components. The discharge head is precision-cast stainless steel. The complete single-phase package includes an external starting control box and watertight heatshrink kit.
