Water supply systems and fire protection requiring significant lift heights from 4-inch borehole installations benefit from this high-pressure submersible pump. It manages groundwater containing suspended sand up to 150 g/m³ and supports continuous duty for large civil infrastructure projects.
A 4 kW three-phase motor at 415V drives the 36-stage assembly, achieving a maximum head of 190 meters and a peak flow of 160 L/Min. The mechanical interface conforms to NEMA standards, ensuring a secure connection to high-performance 4-inch submersible borehole motors.
High-strength LEXAN floating impellers move axially within each stage to accommodate sand particles, helping to protect the polycarbonate diffusers from abrasive wear in deep boreholes.
AISI 304 stainless steel forms the external jacket, with a delivery casing incorporating a built-in non-return valve to shield the 36 stages from water column weight and backflow during shutdown. Rated for liquid temperatures up to 35°C, the unit includes a chrome-nickel steel suction lantern and a Class F insulated motor.
FEATURES
- LEXAN radial floating impellers are designed to handle sand while reducing internal mechanical seizure risk
- High-performance polycarbonate diffusers maintain a smooth hydraulic flow path for improved energy efficiency
- Thirty-six-stage configuration delivers 190 meters of head for high-lift fire fighting and supply networks
- AISI 304 stainless steel external jacket provides structural integrity and resistance to subterranean corrosion
- Integrated non-return valve in the delivery casing protects the pump from reverse water weight and hydraulic hammer
- NEMA-standard coupling ensures compatibility with a wide range of submersible motor units
- Chrome-nickel steel suction lantern with fine-mesh filter prevents debris entry into the hydraulics
- Class F insulation and IP68 protection support safe, reliable performance under continuous well immersion
