Product Overview
Intensive sprinkler systems from significantly deep subterranean reserves require the high-pressure, low-volume delivery of this submersible pump. It serves agricultural water management where reliable delivery is essential, with a floating impeller design that maintains performance in groundwater containing suspended solids.
Wired for a 415V three-phase connection, the 1.5 kW motor draws 4.4 Amps during normal operation. Maximum flow reaches 22.5 L/Min with maximum head of 284 metres at shut-off. The hydraulic performance supports sprinkler system requirements where pressure is prioritized over flow.
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. An integrated check valve in the upper casing secures the massive water column.
Constructed with a 304 Stainless Steel casing and technopolymer hydraulic components. The discharge head is precision-cast stainless steel. The complete three-phase model includes a professional heatshrink kit for waterproof deep-water electrical splices.
