Water reticulation systems and agricultural supply requiring high-volume delivery from deep 4-inch borehole installations benefit from this submersible pump. It processes clean water containing sand up to 300 g/m³ and supports continuous duty for high-demand irrigation networks.
A 5.5 kW three-phase motor at 415V drives the 20-stage assembly, achieving a peak head of 99 meters and a maximum flow of 400 L/Min. Mechanical synchronisation is ensured by a NEMA-standard motor coupling, providing a secure connection to high-performance 4-inch submersible borehole motors.
Durable LEXAN floating impellers move axially within the stage casing, helping to prevent motor seizure when sand particles are present. The high-flow system preserves its hydraulic characteristics while moving large volumes of water from depth.
AISI 304 stainless steel forms the external jacket, with a delivery casing incorporating a built-in non-return valve to protect the hydraulics and motor from reverse rotation and water column weight during shutdown. Rated for liquid temperatures up to 35°C, the assembly includes a chrome-nickel steel suction lantern and a Class F insulated motor.
FEATURES
- Special radial floating impellers facilitate sand passage while reducing internal mechanical binding risk
- High-performance polycarbonate diffusers maintain a smooth hydraulic flow path for improved energy efficiency
- Twenty-stage radial configuration delivers 99 meters of head for high-flow agricultural and civil supply
- AISI 304 stainless steel external jacket provides resistance to mineral corrosion and borehole stress
