Rural supply and industrial processes requiring significant lift heights are the primary applications for this submersible pump from 4-inch borehole sources. It handles clean liquids with sand concentrations up to 150 g/m³ and supports continuous duty for high-demand pressurised networks.
A 1.1 kW three-phase motor at 415V drives the 20-stage assembly, achieving a maximum head of 131 meters and a peak flow of 50 L/Min. The mechanical interface conforms to NEMA standards, providing a secure connection to high-performance submersible borehole motors.
High-strength LEXAN floating impellers move axially to allow sand passage, helping to protect polycarbonate diffusers from abrasive wear. This configuration maintains consistent flow rates in applications where subterranean sediment is a factor.
AISI 304 stainless steel forms the external jacket, with a delivery casing incorporating a built-in non-return valve to prevent water column drainage and motor reverse rotation during shutdown. Rated for water up to 35°C, the assembly includes a chrome-nickel steel suction lantern and a Class F insulated motor.
FEATURES
- LEXAN radial floating impellers are designed to handle sand particles while preventing internal wear and seizure
- Reinforced polycarbonate diffusers reduce turbulence and improve overall hydraulic efficiency
- Twenty-stage hydraulic configuration delivers 131 meters of head for high-lift rural water supply projects
- AISI 304 stainless steel external jacket provides resistance to borehole oxidation and chemical groundwater attack
- Built-in non-return valve protects the internal hydraulics from back-pressure and column weight stress
- NEMA-standard coupling simplifies installation and ensures compatibility with various submersible borehole motors
- Chrome-nickel steel suction lantern prevents oversized debris from entering and damaging the internal stages
- Class F insulation and IP68 protection support continuous duty in deep, fully submerged boreholes
