Product Overview
Municipal water supply networks moving groundwater from 4-inch wells are the primary application for this submersible pump, serving moderate to deep extraction tasks where reliable high-flow delivery is essential. The floating impeller configuration supports continuous operation in water containing suspended solids.
Operating on a 415V three-phase supply, the 1.5 kW motor draws 4.4 Amps during normal operation. Maximum flow reaches 90 L/Min with maximum head of 114 metres. The hydraulic performance supports primary water supply network 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. An integrated check valve prevents back-siphoning into the well.
Built 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-grade heatshrink kit for waterproof electrical connections.

What lift height and volume does this municipal extraction pump provide?
The 4GS15T achieves a maximum head of 114 metres with flow capability up to 90 L/Min for municipal supply networks.
How are the impellers driven inside this multistage borehole pump?
A rigid hexagonal stainless steel shaft in the 4GS-15T provides positive impeller drive across all stages without slippage.
What electrical power rating and current draw apply to this motor?
Powered by a 1.5 kW motor on a 415 V three-phase line, the 4GS 15T draws 4.4 Amps during operation.
Does this submersible unit lock descending fluid columns on shutdown?
An integrated check valve in the 4GS_15T halts reverse water column flow and prevents drainage on motor shutdown.
How does the pump design prevent binding from sand particles?
Floating stack construction allows the 4GS15T to tolerate suspended sand concentrations up to 150 g/m3 without seizing.
