Product Overview
Fire protection systems requiring reliable water from 4-inch subterranean reserves are the focus of this submersible pump, serving critical safety infrastructure where consistent high-flow delivery is essential. The floating impeller design maintains performance in groundwater containing suspended solids.
Operating on a 415V three-phase supply, the 0.55 kW motor draws 1.7 Amps during normal duty. Maximum flow reaches 90 L/Min with maximum head of 42 metres. The hydraulic performance supports fire protection system requirements effectively.
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 non-return valve locks the vertical water column on shutdown.
Built with a 304 Stainless Steel casing and technopolymer hydraulic components. The discharge head is precision-cast stainless steel. Supplied with an industrial-grade heatshrink kit for waterproof cable splices.
